Motor Oil | Fine Print and Misconceptions

After years of hearing the same questions and problems about motor oils, we look at the fundamentals that are often overlooked from enthusiasts and normal car people. Are owners using the correct oil for their application?
Whether you drive a Mazda3, Porsche, BMW or Toyota hopefully there is some information here that will spark some thought. This video is not about promoting a specific oil or brand. Whether you use Mobil1, Royal Purple, Amsoil, Redline or Walmart oil, it means nothing if you don't understand the basics of why and when to use certain oils.

Well I use WD-40 for all my cars and I've never had a rusty engine :)

[@yourhandlehere1]

I've been running Castrol GTX 20/50 in my 68 Corolla for 29 years, all seasons, 800,000 miles so far.

[@savagegeese]

+IcantSignIn Thats kick ass, older motors more clearances so that thick stuff is good.

[@yourhandlehere1]

It's been a great car, most of the original Toyota parts lasted 40 years. The aftermarket stuff, water pumps, fuel pump, starters etc., seem to go out every year or two now.

[@pliedtka]

+IcantSignIn True, aftermarket cheap parts don't last - Reliance alternators, starters are example, but even current production parts often don't last as some in cars made 20-30 ago.

[@TheRebuilt1]

Chapeau to you sire. Yeah the delfi and other like parts manufacturers leave a lot to be desired. My 88 Civic DX alternator just stopped charging at 315k and just rebuilt than risk putting a Denso made in Taiwan part as replacement.

Out of all the oil videos I have observed, including the ones from the mfg's by far, by far this one makes the most sense to me. Thank you for your video

[@VintageSewingMachineGarage]

This is one of the most useful posts on motor oil I have seen in a long time given how much discussion there has been on the topic over the years. The most helpful point here for me was Mark's comments on oil pressure, which is seldom addressed as a factor in oil performance. I have noticed pressure as an issue in everything from my Acura Integra 5 speed to my Buick 3800 V6 (yes, I hear the laughter! ). Each of these cars are obviously polar opposites for the driving style they invite and yet each one was impacted by a change in oil viscosity specs. My mechanic once changed the Acura's oil with 5/w20 and it did not perform as well in summer as with the 5w30 it was spec'd for. (Engine temps averaged much higher). On the other side, the Buick, with its butter smooth (albeit ancient) pushrod design that heralded from the early 60's did not tolerate 5w30 in winter temp even though GM had 'updated' the engine's oil spec to include 5w30 use in winter for MPG reasons. I believe my experience with the poor performance with 5w30 was due to much wider tolerances for things like bearings which resulted in 'rattling' on startup and over consumption of oil between OCI's. With the change back to 10w30 year round, the 3800 was and is a very happy engine with no oil loss between changes. Both cars have full service histories of which I'm very familiar. My point here is that the way an engine is designed and the way its driven can have remarkable impact on oil pressure/oil viscosity performance and needs. The fact that pressure, temperature, driving demands, and viscosities are variables in such dramatically different cars as those I drive supports Mark's contention about viscosity and pressure. Thank you for the insightful video!

[@MiniMorris97]

Loved the vid, great info

[@Slash18622]

This is a really great video and I can underline everything say! Thanks for that! I personally (living in Germany) use 0W40 in winter and 5W40 in summer. I don't own a sports car that a xW60 would be needed. But also, I wouldn't go below xW40 - at least with turbo motors. I rather have a "thicker" oil that is more protective than a super-thin oil that might save me 0,0000001 liters per tank.

[@abcdsz]

Ich bins i am livin in the netherlands. But what you are doin is not that important because germany never gets that coolld or warm. Just stick with a good brand oil on 0w30 or 5w30. I dont know which car you have but see manufacturer recommendations for the right oil the coding is like vw. 504 & 507 and 502 & 505. Be careful what you use and als have in mind if youre using mobil 1 0w40 its not a fully synthetich oil.

[@andrewwmacfadyen6958]

Yes fully synthetic oils even the expensive ester based ones generally have some mineral oil content, and top grade mineral oils will have some synthetic in the blend. Even the cheapest supermarket own brand "synthetic" oils which are based on the cheaper group 3 feed stock are 10 times better than old style mineral oils. Where you have to be very careful is with modern VW, BMW and Mercedes with greatly extended service intervals or any GDi or VW Diesel with Pumpe Duse.

[@corporalpunishment1133]

If their was no wear material in the 0w20 I would say it's ok. The only way to truly know what the oil pressure is doing it to put an oil pressure gauge on the car. No point guessing.

[@pliedtka]

+Corporal Punishment not the pressure by itself- a flow meter would do proper job

[@pliedtka]

+Andrew W MacFadyen I do not follow the extended oil change intervals, nor the computer calculation of oil life left. I seen a couple very expensive engines that are finished and just to sleep at night I rather change it more often and spend a couple bucks more a year than to deal with blue smoke from the tail pipe - simply I do not believe in 20,000 km oil change intervals.

[@Xmvw2X]

[@aasastephenson1538]

[@tiberiusclaudiusnerogermanicis]

good information, well researched and well presented. nice job man. appreciate you putting this out there

[@zaitcev0]

In addition to squeezing through tight gaps, another hazard of thick oil is intake cavitation in the front side of the pump. You can sometimes see the wear it creates: it literally forces the metal to flake out, creating pitting.

[@louf7178]

Pete Zaitcev I wasn't aware of this in any engine oil pump situations. I would think the cold-temperature time is too small for any appreciable cavitation damage. I know in continual operation water pumping systems it is absolutely an issue. Have you seen this happen with oil pumps?

[@Kevinb1821]

I like to use Pennzoil Platinum but that’s just my choice. I’m sure all are fine as long as you change your oil.

[@royrobinson4636]

[@garynorthtruro]

It's hard to believe anyone remains ignorant of the advantages of the synthetic oils. They've been available since the mid 80's.

[@user-fw6xr3ue2q]

Early 70’s

[@deeligee]

In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the "W" number the better the oil's cold temperature/cold start performance.

[@stewartknight7464]

Thankyou for your video, this info is really helpfull in understanding flow rates of oil, etc.

[@techexplorer9382]

On Point ! Good information that is correct for most cases .

[@19910602011]

i use Amzoil 10w 40 synthetic 15000 mile here in the Caribbean and i change my oil at 7500 miles, before i was using a higher viscosity which was causing my oil pressure switch to go bad and leak every month

[@handheldgarage3297]

I'm an Amsoil user too.

[@sergevivier2023]

0w-30 is what I use all year round in Canada but the video is right that in a hot climate, many performance cars like the M3 needs 40 to 60.

[@MRTuning704]

One thing that’s really important to note on the synthetic oil‘s that say they can run for 10,000 miles say that it’s only for newer cars with low mileage Auto/oil manufacturers warn people not to go 10,000 mile on a oil change on a older ,worn/highmileageengine A lot of people have older cars and they’re trying to save money and they put this oil in and they get rid knock and valve noise and can’t figure out why Even in my buddies 2019 jeep says do not go over 3000 miles on a oil change All my Nissan manuals say nothing you can put in your engine will restore it and to only change your oil every 3000 miles So I honestly think the one year/15,000 Mile oil change is a bs

[@jamesmedina2062]

M&R Tuning yes because it’s not sealed oil in gearbox. It’s oil mixing with water and particulate matter and fuel, depending on the car, location, and use. Good point

[@johng.4959]

Great video! Out here in Phoenix, I run various viscosity oils based upon "usage". (As you mention.) What really helps is a "real" oil pressure gauge. ('94 Miata has one, thank you.) So in the summer, I'm running a "40" weight vs. "30" weight. I have seen oil temps rise just from sitting on the asphalt in traffic. It's also important to look at the age of the motor. Older engines often require more viscosity as the bearing clearances increase over time. There's a whole-lot-more to motor oil than the average consumer understands. Thanks for another informative video!!

[@smashingartful]

Just a general comment concerning your whole channel. Mark I think this is one of the best car channels on youtube. I stumbled on it a few days ago and can't stop watching. You can go to some channels and get a 435 point break down of the exact composition of the polymer used for the left break light housing but somehow something is lacking. Other channels have the reviewer giving his impression of the car but somehow every car ends up being “awesome” or “terrible” they all just kind of blend together. You have somehow nailed the perfect middle ground. Entertaining videos where you have clearly done legit research but you're able to actually get across to the viewer something special - a real sense of feel for the car. I’m not exactly sure how you do it so well but after watching you review a car I legit feel like I took it on a test drive. The way you describe things in a clear succinct way just makes sense. Also your relationship with Turbowksi is really compelling to me. You guys can go from the 8th grade humor of a quick dry hump while the other isn’t looking to a fairly deep conversation about the cars you’re reviewing. I think it’s cool to watch because you both seem like real people. Anyway, really love the channel, thanks!

[@MarzNet256]

Full synthetic oils can last up to 15k miles without significant breakdown. However, the oil does become contaminated with combustion products and material from engine components which basically turns it into liquid sandpaper. Running your oil for more than 6-7k miles is asking for trouble. I change mine every 5k and run full synthetic.

[@savagegeese]

+MarzNet256 Have you ever sent your oil to a lab to confirm that? Because modern filters and oils do am amazing job at encapsulating debris along with modern motors having less issues with creating by products. As posted in the video at 15k miles on a oem oil it had more than enough life left and the filter was in excellent condition as well. I am with you I would not do it but running less than 10k miles on modern motors, group 5 oils with good filters is throwing money away.

[@mike-uw6wt]

You’re just making stuff up.

[@rosen9425]

Those are 1980-1990 type of oil changes. No oil / car manufacturer in their right might would claim 15k if wasn't possible, and engines have much lower tolerances today than 20-30 years ago. Of course it's a good idea to use the dip stick more than once a year to confirm how things are going down there, might need a squirt or two at some point which is far more dangerous to miss out on. Top-spec specific oil is hellish expensive (it's a brand tax issue mostly), so I've done 10k mostly before (one year limit) and 18k oil changes the last two (added driving, still one year) and will continue to do just that. Only 95k miles on the car so it absolutely shouldn't burn oil which it doesn't. But reading oil comments means my engine should behave like an old diesel running on bunker fuel which is also...not the case.

[@blackericdenice]

MarzNet256 Newer engines don’t have as much blow by. I change my 2016 F165 myself every 8 to 9k miles. I have a few videos, it has 44k miles. Ford say don’t go over 10k miles.

[@horiatomescu]

If you pay attention, to the sound of your motor, I promise you will know when to change it. Another thing is when you smear with the stick, a drop on your fingers, and try to clean it.If the black isn't coming of by rubbing it with your finger, and you can still see some shady black mark...is overdue

[@thesnoopypanda]

wow, was completely expecting you to give some bullshit advice to the point I actually put off watching this episode. Very glad to be wrong. I appreciate that you stayed away from the brand banter and focused on the actual important aspect of spec'ing an oil, the intended usage and operating temperatures (ambient and engine).

[@kainhall]

i live in north east montana.... -40f is common my 99 buick century calls for 5w-30.....and i run that in the summer but 0w-30 is MUCH better in the winter....you can just hear the motor and lifters make less noise on a TRUE cold start i also change it as soon as the oil change light comes on......i know im probably wasting money.... but it has 205K miles on it.....ill spend 25 bucks to change it before it ever gets CLOSE to actually needing to be changed and at that mileage....things are probably wearing out quicker anyway.... might as well give it the best chance at hitting 300k

[@asherdie]

@Steve H. bullshit.! 250,000 miles on 5.3 chevy cheap oil only change filter and oil every 6 months.

[@Mike-cz2yw]

@Steve H. Penzzoil ultra platinum is better in cleaning ability, wear tests (with a proper additive -> its dervide from natural gas so is more compatible with additives), and oil flow rates (natural gas is thinner and flows easily, including in cold temp). amsoil is fantastic oil, the signature series is probably the best on the market BUT grade 3 mineral oils like Pennzoil ultra do have benefits over grade 4 PAOs like Amsoil...such as what I listed.

[@TENNSUMITSUMA]

@@ffagilar22451 they're probably going to ask what year make and model the car is. 2 the sale is while supplies last at the time period the sale's running. meaning you can tell them whatever you want, it's not going to mean fuck all.

[@jaredk2jpk535]

So do you buy oil based on ambient temperature or engine temperature? I live in upstate NY, so the temp can range from -20F to 100F during the year.

[@stevensevek6151]

@jonny j Engine temperature... So when you start the car in the morning the engine temperature is the same as the ambient temperature and the high engine temperature is dependent on the thermostat's rating (usually around 185°F.).

[@Zappateer]

Great video, I can tell a lot of work was put into it! This was also the first I heard of the Toyota 86.

[@matthewyang2792]

Great video, love your humor as always!

[@tarassu]

If you live in a cold climate with M3 and you don't want to switch oil's like an idiot between summer and winter: I would recommend installing auxiliary fuel heater (optional extra for BMW-s) or cheaper option is electric block heater. You warm the engine up in the winter to room temperature before starting. Never start 10W60 in very cold weather without preheat. Even if "I really need to buy a burger" scenario happens.

[@37rmstrong]

Question. Do all 0 weight oils have the same viscosity at 0°? For example the same manufacturer but a 0w20 v a 0w40 etc?

[@Xmvw2X]

The weight spec has a range. For example, all 5w30 oils fall into a specific range in order to be called a 5w30 in the first place. Well, there's two specs, the 5 and then the 30. It's easiest to think of the 5 as the cold weight or the weight of the base oil. The 30 is the hot viscosity equivalent or effectively the result of the additive package's ability to keep the oil from thinning out as fast when temps rise. For example a 5w30 and 5w40 may have the same base oil but different additive packages to make one thin out a little slower than the other at higher temps. The 5w30 is effectively a straight 5 weight oil cold, but it mimics a straight 30 weight oil when hot and can do so only because of the additive package used. The weight values are a spec. There's a scale and a 0 weight has a certain range, a 5 weight has a certain range above that, a 10 weight a range above the 5, and so on. There's a spec at the cold rating (32F/0C) and a spec at the hot rating (212F/100C). To be called a 5 weight, the oil has to be within the spec range. If it was formulated differently and ended up thicker, it would be called a 10 weight instead. In this sense, ALL 5w30s are the same (near the same) at 32F/0C and at 212F/100C ratings. However, they are NOT the same below 32F/0C and above 212F/100C. This is where the actual oils and additive packages different. Some manufacturers have other specs beyond these two ratings. In some cases you can find a viscosity rating at -40F/-40C. You also have a separate rating called a Pour Point which defines the coldest temp the oil is still pourable. By pourable, there's a certain spec of flow rate, sort of like what was done with the funnel and jar in this video. To still be considered "pourable" it would require at least a certain level of flow. Once it falls below this rate, that's its limit. Generally you will see two broad ranges. One is old fashioned petroleum oil (dino) which has a pour rating of around -35F give or take some. The other is synthetic oils. These tend to have a Pour Point of around -50F to -60F, as it they flow better colder than petroleum based oils, even at the same rated viscosity. In general, any oil with a milder additive package flows better colder. A 0w20 will flow better colder than a 0w30. You will generally find the Pour Point to be lower and the viscosity at -40F/-40C (if given) to be lower (flow better). As well, you will also generally find a higher base weight to have better high temp performance, so a 10w50 with stay a little thicker hotter than a 5w50 would. There's very little data on this aspect though, no real specs, and only some graph data floating around drawing more extended curves vs temp. You will basically always find synthetic oils to be superior for both function and protection. They are also cleaner oils with less natural contaminants. The research out there basically says it's no contest here. Synthetics are the champs hands down. The only time you can't use a synthetic is if you're breaking in a new engine because it protects too well for the break in procedure. Also, as you may have suspected, an oil like a 0w40 is a better all-arounder than a 10w40 or 0w20. These super oils that cover the wide spectrum are kind of the do it all oil that can handle both extreme cold and extreme heat. You can get as wide of a spectrum as a 0w50 or a 5w60, and these cover the range extremely well. This means you can buy something like a synthetic 0w40 and get outstanding winter performance, great cold startup, and still have excellent high temp performance. Two things to note, generally speaking. Thin oil flows high volume. High volume flow means great cooling. Thick oil offers higher protection from metal on metal contact. At the same time, the engine design and clearances between parts defines flow rate and oil pressure. As was pointed out in the video, you can go too thin and loose oil pressure. You may need a higher performance oil pump to compensate. There is a balance in between protection and cooling that oil must do. If you go too thick, you may find that the flow volume is not there, and you may get heat build up in parts of the motor due to low flow and lack of oil collecting and evacuating that heat away. I have not seem much for data on this stuff personally, so I can't comment on specifics. Just understand that some of the recommendation of the oil viscosity is based on the balance of the two aspects. It's just a very fuzzy area for consumers because there is very little test data. Most of the knowledge seems stuck at the manufacturers.

[@savagegeese]

+Xmvw2X Hell of a post, superb.

[@Xmvw2X]

Thanks, right back at you for making hell of a great video. I love these types of discussions. Reviewing cars is only one part of the automotive world. There's a massive amount of technical content as well and a lot to learn. Jason from Engineering Explained has gained a lot of popularity tapping into this portion of the car enthusiast world. He's a smart guy but also a novice in a lot of ways, researching and learning along the way in order to present interesting content. He isn't coming from high experience though, so the presentation is different. You've gained quite a bit of knowledge from your own passions and interests, so I'm happy to see you formulating some of that acquired knowledge into consumable bits. I especially value the high level of experience. This brings a lot of insight and wisdom into the discussion, even discussion tailored towards a casual viewer. A great example is Randy Pobst on the Racing Line from Motor Trend. There too is a high level of experience, high knowledge content, and a presentation that's extremely insightful and informative without being overly complex and alienating to the consumer. You brought the same level to this video, and that was wonderful, very well done. I'd love to see more topics covered. You've hinted at one in the video: tires. Ideas could be more abstract too, for example discussing the ideal seating position or discussing what fundamentals make a car fun to drive. Some of this stuff you think about on every single car review and use it as part of your evaluation and discussion, but it's these things that can actually be their own discussion topics too. Keep up the good work on everything you do. I know you work hard squeezing this stuff into your already full life, so I very much appreciate that you take the time to create for others.

Oil change intervals vary. The X1 is a daily and I travel 30,000 miles / yr so I replace the oil every 10k. The 328 are out only 8 months / yr only travel 4000 miles/yr so I change once a year (prevent moisture build up). You can hear the difference when starting a car in cold temperatures with proper thin oil.

[@stevensevek6151]

I don't know how old your Lexus is but it likely says 5W instead of 0W because 0W wasn't available when your car was made. When OW-30 became available I started using it in my 1996 Honda Accord Wagon which called for 10W-30. Never had any engine problems when we let it go to our son about 3 years ago with nearly 200,000 miles. Still used no oil between 7,500 mile oil changes. It is available in many brands.

How do you know what oil pressure is "catastrophically low"? Toyota just specs a min.@80C. That 0w20 UOA was very good. Also 265-270F is not stupid high, but about max i would go.

[@savagegeese]

+homemadeHonda Most service manuals specify normal and low oil pressures based on a given RPM. For example at normal operating temps for many motors for every 1000 RPMs youd add 10psi of pressure. So at 2000rpm 30psi, 3000RPM 40psi etc. So as oil temps climb outside of normal range you'll see pressures start to fall below spec. So on a car with a 7000rpm redline you should see 80psi. When you start seeing half the pressure it's a rule of thumb to back off or risk damage. Higher the rpm, higher risk.

[@krrk6337]

@savagegeese The pressure is measured at the oil pump so if it's low it means it's flowing better. What does the pressure have to do with damage? The lab test result you showed it was good.

[@IR-xy3ij]

​@@krrk6337 The specified oil pressure is the pressure measured at the sensor's location, which is typically at the pump or filter. Also oil analysis does not usually show engine damage because the particles are typically retained within the oil filter, and the only way to reliably check for engine damage is to physically examine the filtering media and the engine itself. Oil analysis is only capable of showing whether the oil still meets the specification.

Scott I sold the BMW M3. The level of Motorsports was too much for me.

[@ErwinSchrodinger64]

Yes, there are so many car myths and the story I'm about to tell you should not be taken too lightly. I remember one time I went to the gas station and accidentally put diesel 3/4 into the gas tank. My car was a high performance stock Honda Civic Si with the aerodynamics package (while the package didn't increase horsepower, from my understanding, it made my car a knife in the wind which was the equivalent to adding 90 horsepower to the wheel). Needless to say I was worried that I wouldn't be able to race a Toyota Corolla in a hour or two. However, it wasn't just any Corolla but the Corolla-S. Luckily, I called my friend Bryan, and he told me to just fell up the rest of the tank with water but make sure I used Kentwood water because it has special additives. Unfortunately, I didn't listen and instead used Dasani Strawberry Flavored Water (it was the only water on sale). When I turned on the car I noticed right away the additional horsepower the engine created from the loud noises coming from the block itself. I knew immediately that the potential of my large block DOHC 2.0 inline-4 with the K&N air filter had been unleashed. When I showed up to race the Corolla-S, I revved up my engine and people were starring because of the fire emanating from the Honda exhaust system. The driver of the Corolla-S was so scarred that he was crying (he knew he was defeated). The race began and my special fuel mixture with additives produced so much horsepower out of the K20 engine that it lit both the engine and exhaust on fire. I beat the Corolla-S for the 1st 30 feet but after that my car just disintegrated, literally. I learned that day one of the greatest car myths ever: when mixing diesel fuel + water, to substitute for gas, you must use Kentwood mineral water because of the additives. It's been 2 years since that epic race and I should be getting out of the hospital soon due to the 3rd degrees burns I experienced from my car blowing up that day. I'm ready to start driving again. This time, when I'm ready to race, I will know the proper diesel fuel + water to add to my car. I will keep everyone posted. OK, thanks.

[@OverlandTT]

My Porsche Cayenne V8 uses 0w40 Mobil 1 from the factory. They also say it's a 20,000 mile interval. It's redline is 6500 rpm which is high for a V8. The Porsche has dry dump lubrication and in addition to a coolant temperature it has oil temperature gauge so I guess at the track I'd know if I'm frying the oil, right?

[@derrickg5612]

That's nice it has an oil temperature gauge. My car doesn't, but I don't track it so no big deal. Your Porsche probably has an oil pressure gauge as well. You will know you're frying the oil when the pressure drops off, just like it was explained in this video. While this information is good to know, your Porsche will give you a warning indication if the oil temp or pressure goes out of operating range. It might even limit the power output to make sure nothing is damaged. This information is absolutely necessary if your car doesn't have these fail safes and is a track vehicle. As for the 20,000 mile interval. I have my own opinion on that. I personally think it's too high. Yes, the oil itself can probably take it, but the oil filter still needs to be changed. The filter can still get clogged and cause flow and pressure problems, but your Porsche's ECM is monitoring pressure and would warn you if it drops. And it's a dry "sump" lubrication system

[@joszer]

iVlog I place 0w-40 in my 2012 Z06 for Daily and Track duty. It'll see 250-270° oil temps and my pressure has always been good. Few Corvette members have sent in their oil for analysis after track days and it's always come back good for the Mobile 1 0w-40. The Z06 also has a dry sump system and also redlines up to 7000.

[@OverlandTT]

Thats good to know Joszer, how many miles/duty hours are you guys seeing between changes and do you use a chemical flush also. I didn't realise that Z06 had a dry sump lube system, its great to know as it was something I had considered quite a while ago. What year did GM introduce dry sump and is it also on the Camaro?

[@joszer]

I usually do about 4 track days before swapping out the oil. That equates to about ~2000 miles of hard driving. That factors in the mileage to the track and back since it's about 150 each way for me. I just do a simple drain and fill, no chemical flush at all. Also as far as I am aware (& after after a few minutes of googling) only the 2013-2014 Camaro Z28 and the new 2017+ Camaro ZL1's have dry sumps. All the others have a conventional wet sump systems.

[@elr2141979]

iTheGeek which boggles my mind because car companies have Engineers to figure this stuff out so we don't have to.

[@fkmbmw]

Its not a theory and please don't throw words online without any background knowledge, someone would might read your comment and ends up fucking up their car. Call a major motor oil company, ask them what does the numbers on their products mean, then come back to me (they will tell you it reps celsius low and high respectively). Fun fact your engine gets cooled by radiator coolant lines beside the engine block through tunnels and passages. Fun fact #2 your engine oil temp does not show the exact temp, it goes up when there is a major problem in overheating. Plus, having a thin oil (aka designed for cool climates) won't harm an engine right away, but it degrades faster with everyday heavy usage in hot ME or Australian deserts for example much much much faster than a heavier oil for example, rendering the thin oil to lose viscosity much faster that causes problems right away. You are mistaken engine temp with oil temp. Ask yourself why does heavy duty designed cars, or cars designated for Middle Eastern markets are fitted with bigger oil cooler and added with a dedicated transmission oil cooler? Plus, dealerships over there abide by manufacturing rules and PUT HEAVIER OILS (10/20w-40/50)in their cars that are identical to the ones we see in the US markets.

[@recoveringnewyorker2243]

O.K. Dumb question ; I'm in Florida and a (long) retired auto mechanic and fire truck builder. My 2013 Hyundai Sonata (for example) recommends 5w20 on the oil cap. However, the owners manual (and dealer service dept.) recommends 5w30 or 10w30 in hotter climates. The dealer uses 5w30 so that's what I use (synthetic) and still change it every 3,000 miles (very old school) . My friends 2012 Scion tc says 0w20 AND NOTHING ELSE. I don't want to go against mfr recommendations but is 0w20 (synthetic) too thin for a hot climate like Florida? And would an additive like Lucas synthetic oil stabilizer help?

[@savagegeese]

+Shepperd November Is your Sonata turbo? For Forida no reason to run a 0w20. You can run 5w30 and that will give you better upper end viscosity while balancing cold start performance. If you do a lot of driving, idling and tons of summer driving with turbo then 10w30 just ups your high end viscosity even more. Just takes more time to get up to temp.

[@recoveringnewyorker2243]

savagegeese No , it's not a turbo. I do A LOT of highway driving . What about the Scion? Toyota say 0w20 regardless of climate. But I believe it's too thin for Florida. What say you?

[@fadimo305]

Shepperd November, do not go a normal weight above manufacturer recommended. Just buy a better oil that maintains its rated viscosity at very high temperatures.

In order to eliminate that variable you should do the pour point test with the same brand. Red line uses a different type of base oil than those other brands. I think you would even see different result if you compared 10w60 between red line and pennzoil. Again great video.

Older small engines from Japanese manufacturers just wouldn't heat up unless on the hwy - my older Civic has this problem and block heater was the only solution to the problem.

[@K03sport]

Thanks for the video, but I'm not sure why this is such a hard thing to understand. If the owner's manual is well written, it will give owner's a choice of oil viscosity (weight) to use based on condition, i.e. temperature, such as our Nissan Pathfinder's manual does. It says that 10w-30 or 10w-40 may be used if ambient temp is 0*F - 100*F+; however, they (Nissan) say 5w-30 is preferred for ALL ambient temps (page 9-7 of owner's manual)...it has seen 5w-30 synthetic at every oil change...when in AK, everyone put oil & trans pan heaters on their cars to "help" the fluids stay warmer so they would reach the important parts faster....at -30*F, you don't want thick oil...actually, you don't want to be outside, but that is a different story. I'm hoping in the winter/extreme cold, that people aren't tracking their cars, but I guess you could ice race, but then, why would you use a $50K streetcar? What does Porsche run in their cars during their winter driving events? Simple - use oil that meets spec, meets MFG's recommendations, and matches the conditions you are driving in...still not sure why this is hard to understand.
