I have been building and tuning engines since the early 80s. I always read and update my knowledge base on my industry. Or at least I thought so. I stumbled on the Lakes videos about a year ago. I quickly found out what I didn't know. Thanks for hosting Lake on the channel, you now have a new subscriber. Well done gentlemen.

Good attitude to have. Some people are stubborn and don't want to change with the times. Humans have advanced so much further in the last few decades than they did the previous century.

[@GNX157]

In addition to Lake’s recommendations, I would suggest using “top tier” fuel at a fueling station that displays the top tier sticker or label at the pump. There’s a web site that has a searchable list of top tier gas station locations.

Same people fight so hard about premium gas but it’s not just that it’s a quality fuel station with a high turnover. I have a car that specked for 87 and I don’t care what anybody says premium. It has a 13 to one compression ratio my wife’s car has an 11.5 compression ratiothat has 120,000 miles on it. It was 87 when it was new however it’s not a new engine anymore. It has carbon deposits carbon deposits effectively raise the compression ratio.

So use synthetic oil, change it every 5k or less and use complete fuel system cleaner every oil change eg chevron techron complete fuel system cleaner. The big unanswered question is.. what about oil weights. Car manufacturers trying to get better EPA figures are recommending lower viscosity 0w20 oils. Perhaps 5w30 or 5w40 would actually result in great protection with minimal impact on fuel economy? Please ask LSJ back or some other true expert to answer that. Thank you!

[@blackhawkgamingtv6553]

According to another one of his videos, always use the manufacturer recommended oil weight, heavier oils can clog extremely small oil passages.

[@danielk7111]

@@blackhawkgamingtv6553I don’t recall him being absolute on that. I own an engine that has no problem yet but it seems they all eventually have a rocker/lifter failure. The rockers’ needle bearings can eventually stop moving to disperse wear so it ultimately leads to the camshaft lobe being wiped. In that situation, where the actually viscosity, the layer boundary, is the first line of defense against metal to metal contact. Based on that, I think that the locality of failure has higher temperature that needs a higher HTHS centistoke value at 150° C. Looking at old school big blocks where Lake gave advice (yellowbullet forum a few years ago) on hydraulic lifters saying they saw good performance from 3.8-4.1 cSt at 150°, I think it at least may show a direction to lean toward over and away from the factory spec to address wear. Yes the passages are small (vvt) and also may cause a hundredths of second delay in actuation, but the benefits MAY outweigh the negatives. If it makes a racket under the hood on 0w-20 when cold and warm…and you say go to a 5w-30 and it is significantly better cold and hot, you may be onto something. Of course, it needs a good additive pack too in the event the oil is displaced from the part’s surface, resulting in metal to metal contact, as a safety net. That’s why the additives are there, a safety net. Also, in my experience, I don’t assemble engines with 0w. Startup, especially fully cold, is where most wear occurs. I’d like some more resistance to the oil flowing away from the journals and splash lubed rockers. Especially since I have start/stop.

Choose weight based on climate. If it's hot, you can go heavy..if it's cold weather, you run the risk of friction and wear on parts with thick oil that don't get up to temperature

[@dannyelregio]

I own a 2009 Honda CRV. I live in Latin America. In the US, user's manual for this car calls for 0w20 only. However for the same engine, same model, same year, but for a vehicle purchased in Latin America, the user's manual calls for: 0w30, 0w40, 5w30, 5w40, 10w30, 10w40 and 15w40 😅 so, there're other factors such as regulations in play besides engine specs

[@chriswoodward5368]

Wonderful video. Yes if you want to be an a student oil sampling is the way to go. As a former fleet manager every truck, we had got an oil sample at every oil change. It allowed us to keep tabs on engine health and comparison to the rest of the fleet. By switching to mobile Delvac one we went from 20,000 mile oil changes to 100,000 mile oil changes And filters every 25,000 miles I would never recommend this in a car. And before anybody says anything, our fleet averaged over 1,000,000 miles per engine overhaul, which is more than we got with conventional oil and 20,000 mile oil changes.

[@captnjim44smith74]

Great report Chris, it validated what I have been saying about synthetic and oil change cycles. For over the road truckers, a savings per truck adds up to profits !

[@mason7300]

I do oil samples as well. And it gives me confidence to do 10000 miles on a change. Oil checked good as new. I could go further but I’m ok with the 10000k miles. It does depend on use and vehicle so an analysis would let you know where you are with your specific vehicle and use. Some instances will not make 10000 before breakdown. And your 100000 intervals are amazing but is probably from a lot of proper operations and procedures.

[@captnjim44smith74]

Yes, I agree with oil sampling, but years ago, petroleum oil was what was being tested. Today, with pure synthetic oil, results should not be viewed as they were. I saw a technical paper saying synthetic doesn’t wear out, it just gets dirty and contaminants, so I change oil at 24,000 miles like some trucking companies !

[@mason7300]

@@captnjim44smith74the thing that concerns me is the contamination as well. I think that is what wears chains and guides. so I do get the results on contamination but it is low when I change it. Even though the oil checks great. but it is there compared to new oil. Some have the oil polishing equipment like ships and trains and the oil lasts many years. I’ve seen it in vehicles. Cheaper to change oil.

[@captnjim44smith74]

99% of these automotive engines do not have cylinder sleeves, they are just cylinders within the engine block. They are not removable sleeves like you would find in certain heavy truck and equipment diesel engines. Also, using the accelerator to the floor method is not to purge and engine, it is to prime the engine’s oil system by developing oil pressure at lower rpm with minimal force on the rotating assembly prior to the actual start. Great choice bringing Lake on the show, I really liked the interview.

My vehicles manufacturer specifies an ACEA SP 0w30 rated oil. Not an easy oil to find. I have discovered ACEA c2/c3 oil meets the same basic emission requirements. I know the minimum HTHS are different for each, lower for c2. Since my engine is a performance engine, and I don't care as much for emissions systems like the catalyst longevity as I do for wear protection, I lean tward using a higher HTHS rated oil. Since the ACEA c1/c2 oils have lower SAPS, to also help with emissions systems longevity virus higher ash content found in ACEA A5/A3 oil that helps protect the valve seats instead, I go with a 0w40 ACEA A3 oil POE/PAO oil.

@@jeffreyb1451 I've gone through the Amsoil production facility in Superior, WI. There are different groups of base lubricants. While the original product may have come from the ground, the hydrocarbons of the Group 4 chemicals are truly manufactured and behave much differently than petroleum-based motor oil. Upon arrival at the plant, a sample is analyzed by their chemists to see if it meets the required specifications. If it doesn't the tanker or freight car is rejected. The manner in which the base chemicals and the additives are blended together helps establish the proprietary nature of the oil and the properties of the oil sold to the public through a dealer network.

You mention oil advertising. When I was in high school there was a late night TV commercial where they ran a normal car (normally a Honda Accord or similar) around a track stock, drain it, add the Wonder Oil (mystery oil) and run it around again. After 10 laps they’d poke holes in the drain pan and let all the oil drain out, supposedly, and run it around the track with only the residue of their Wonder Oil left in the engine and the car would just go, and go, and go……. We called it ‘Wonder Oil’ because we wondered why the heck people believed it. Then caught a lot of grief because people are gullable.

Why everyone suddenly desperately "needs" 100% synthetic oil? Are blends etc. "bad" (like useless)?

[@oneninerniner3427]

Synthetic lubricants can't be beat, well maybe just one way, price. But otherwise synthetics kick conventional & blended or semi synthetics oils butt. Also there are no rules or anything that says how much synthetic needs to be in a semi synthetic. I've heard many are like 15% or even much less synthetic so, just use your full or 100% synthetics and don't look back IMHO. I believe AMSOIL gets their additives from Lubrizol, at least they used to. Premium synthetic molecules like PAOs are polar neutral so they don't attack oxygen which when combined with the byproducts of combustion, fuel, moisture turn acidic & break down into varnish and sludge. Along with other positives like thermal stability, low volatility and the ability to clean and keep engine intervals clean.

[@Noksus]

My engine oil smells really badly of gasoline. I suspect that it is because of short trips that don't get the engine hot enough and lots of cold starts in the winter. I just changed my oil about 1k miles and one month ago and it still smells. Not all of the old oil comes out so that is still contaminating it, I guess. I don't think my driving since the oil change has caused more gasoline contamination because I have tried my best to let it warm up and it's summer right now. Could also be I have a clogged up injector. I probably should do another oil change before 6 months to get rid of the contaminated oil...

[@daleyaeger298]

Just a quick note. I had a car that went 170,000 miles without an oil change. I used Amsoil Signature Series 100% synthetic, the Amsoil spin-on filter, an Amsoil By-Pass filter combined with an annual oil analysis. After 9 1/2 years, the test ended when the new owned of the vehicle totaled the car.

[@DrivenWildOutdoors]

Wow, that was a lot of miles

[@daleyaeger298]

@@DrivenWildOutdoors The best oil combined with the best filtration backed up with oil analysis can blow our mind on how far we might go on a single oil change. However, every vehicle, driving condition and engine design will give different results. Oil analysis recommended an oil change in my Tacoma after only 30,000 miles.

[@NoName-tz5ji]

The bypass filter was the game changer.

[@daleyaeger298]

@@NoName-tz5ji Absolutely, true! The by-pass filter takes 10% of the oil passing for filtration and makes it analytically clean, filtering to less than 1 micron. Filter changes provide fresh oil and ultimately the TBN (total base number) moves toward the acid side, and the oil has to be changed.

[@scottpearce7466]

WHY?

For owners of new cars, can these oil samples be used if issues under warranty arise and manufacturers refuse coverage.

Good question. I don’t see why not.

I have some STP Fuel Injector Cleaner that isn't PEA based. Should I throw it out? My engine port injected not direct.

[@MrRmeadows]

Been a couple years since last time I put any STP in. Not sure how much to use. The bottle says it good for up to 28 Gallons. My tank is only 13-14 gallons. Should I use only 1/2 bottle or full bottle? I planning on checking the fuel trim before and after treatment. Is that valid test? My trim is within a few percent at idle. But is like adding 17% at 2,000 RPM. Does that raise any red flags?

Just change with any SAE certified oil ever 3000 miles. Change the oil filter every other oil change so reduce the initial oil starvation.

[@jamesharris8652]

I us Amsoil 2 and I go 25,000 on my cars using Signature Series.

[@daleyaeger298]

The Signature Series is the top-of-the-line product from Amsoil. And while their other very capable oils are less expensive, I just can't see myself buying "de-engineered" oil to save some money. I am a true "cheap skate" - but not when it comes to engine oil . . . . I have saved a lot of money over the years. I remain a DIYer.

Change your oil sooner than later...22,000 miles on my 19' Rav 4, 5 oil changes...

[@GNX157]

21:35 Purging? You’re not purging anything. What you describe is what can be called “clear flood mode”. It causes the engine to crank over but the fuel injection system is supposed to withhold fuel by not pulsing the injectors, indirectly causing the engine to not start, unless it actually was flooded and it may sputter to life. The alternate purpose being to get the engine to build oil pressure (thus filling the oil filter, NOT purging it out) without combustion loads on the bearings of the crankshaft and con rod bearings.

[@DrivenWildOutdoors]

Yes, I know the actual term, I just refer to it as purge for the oil aspect. Thanks for watching

[@bigdaddymak1439]

Why are the oil manufacturers selling longer OCI also??? I've been doing longer intervals since the late 90s. The problem with today's vehicle owner is they never check their oil! Everyone of these modern engines consumes oil to get fuel mileage. I keep my vehicles topped off and have had no issues with longer drain intervals

[@lonniebeal6032]

I was shocked by 10k mile or one year OCI from Toyota when a coworker bought a new one. But they were using full synthetics, and I know with a good motor that oil will be fine.

[@FHollis-gw4cc]

I have a question that I have never gotten a reasonable answer to, so I'll ask it here. We all have a "full flow filter" (oil) on our engines. Now, I have a problem believing that, assuming let's say 10-30 oil, at cold engine startup, at an ambient temp of 10F, all the oil is passed through my oil filter and not the bypass. Am I correct? How much oil (in GPM or any other measure) can pass through a factory (you pick it, Chrysler, Ford or GM) oil filter at the various temps that it is subject to? I'll bet I'm not the only one here that would like an answer to that.

[@Craig-l2l]

I forgot ask question about my 07 impala LS must follow gm manuel.it said must require full synthetic,follow every 5 k miles for oil changes.must do that ???????.

My car takes a synthetic blend 5W-20 can I run full synthetic without damaging anything

[@DrivenWildOutdoors]

I would follow up with a dealership and ask them that question for warranty purposes. However, I switch from a synthetic blend to full synthetic Motorcraft and the service manager at my dealership said it would not affect the warranty . But I suggest you do your own research.

[@LA_Commander]

Synthetic blend is the bare minimum to use under warranty. You can always step up to full synthetic any time. Just use the correct viscosity.

[@ralfrufus6573]

@21:48 What does "purge an engine" means?

[@ramonahumada4]

Thanks a lot for the info! Thanks to oil geek I’m changing the oil on both my Broncos every 3 k or 6 months! My question is, and I know what the answer is, but is it ok to change my oil every 4k or 8 months on the maverick hybrid?

[@richcombs4805]

Keep in mind start/stops are the worst for an engine and what do hybrids do? They put engines thru the worst of frequent starts and stops and quite possibly never letting it get up to temperature.... I would change a hybrid oil MORE often.

[@ramonahumada4]

Makes sense.I started every 3 k, but when I drain the oil it still looks super clean!

[@richcombs4805]

​​@@ramonahumada4 well you could send a sample and Lake will review it via his Speediagnostix business like he did for me and then you could get a baseline to use to gauge future readings against. Winter time with short trips with generic gasoline should be the worst case time period. On that note, don't use generic gas.

Modern oil filters remove 90+ % of small ultra fine metal particles on the very first pass through the filter. Fleet vehicles like fire trucks, ambulances, police cars, rental cars and most every none “car guru”. Never receive a break in oil change early. It’s 5,000 or 7,500 miles on the first and every subsequent oil change. Often using the cheaper oil and cheaper oil filters. Despite running all day long. Despite reaching 130mph daily. Think about the state trooper who gets a new Dodge Charger on a concentrated patrol week. It will be involved in at least once car chase at 140+ the car will be driven 5,000 before the first oil change if not 7500 depending on fleet maintenance requirements. That Charger will be driven hard daily for years. Then sold to a county sheriff who will drive it for another several years. Then auctioned off and used a a taxi or such. Look at the crown Vic cars still in use.

if it can last 300k with lousy maintanve it can last 600k with great maintenance

[@orinmangar2333]

A question I have is the dealership usually places a sticker on windshield stating next oil change mileage or six months whichever comes first. Can a person who doesn't drive a lot go over the six months b4 an oil change?

Best not to, due to condensation or dilution, since you likely arent often driving till good and hot.

[@randy74989]

@@richcombs4805 It's a personal preference. Oil & filters are cheap, but engines are expensive. Just watch The Car Care Nut or Scotty Kilmer to learn about oil changes. And, the Motor Oil Geek agrees, six months or 5K, whichever occurs first. I don't care how many miles you drive... change the oil & filter, period.
