[@highrzr]

Good video. Oil changes are a lot cheaper than parts changes. The OEM maintenance schedules are based on "normal" driving conditions. Unfortunately, most people's driving conditions fall under "severe" driving conditions which have shorter maintenance intervals.

[@TheOnespeedbiker]

Agree. Normal driving conditions is a poorly understood concept (usually the minimum requirements for engine warranty repairs) and also more designed to comply with EPA extended maintenance mandates than engine longevity. Just assume the severe driving oil change schedule means normal driving conditions; IOW minimum 6 months or 5000 miles. And if you actually have severe driving conditions such as towing, extended stop and go driving/ extended idling, or numerous short trips under 20 minutes where your vehicle rarely reaches operating temperature or only does so for a short period of time (exasperates oil dilution especially with GDI engines), drop it down to 3000 mile intervals.

[@sovietrepublic38]

@@TheOnespeedbiker speaking of severe driving, I've seen idiots flooring their cars when backing up in parking lots. Not only it is dangerous, but they are also ruining their cars. Can you imaging reving an engine to 5000 rpm when it's cold?

[@TheOnespeedbiker]

@@sovietrepublic38 One thing many don't consider is the opposite, that being rarely driving with your engine over 3000 RPM. One of the main reasons for 7-10 speed transmissions is super overdrive for better MPG. My 2021 Jeep Cherokee with a Pentastar engine is only turning about 2000 RPM at 70 MPH, meaning the engine is rarely spinning fast enough to burn off carbon deposits.

[@sovietrepublic38]

@@TheOnespeedbiker yes, you do need to rev the engine over 3000 rpm sometimes. I put in lower gear on highway for few mins once in a while to burn carbon, but definitely don't want to do this when the car is cold.

[@TheOnespeedbiker]

@@sovietrepublic38 LOL no, not when cold. Interestingly with the Audi A3 with the 2.0 TFSI, when driving the engine at just over 3000 RPM raises the temperature and puts the engine into a “cleaning mode” where it runs leaner and hotter clearing out a lot of the carbon build up around the intake valves (a chronic problem with all the GDI engines). I don't know how good it works but Audi recommends you do this once a week for 15 minutes.

[@anonymike8280]

That is a good move. With a 2000-mile oil change interval, you do not need to use any kind of special filter either. Low-end and no-name filters are made to go 5000 miles, but not more. I got a one-owner 2001 Camry Le four with 143K on it back in early 2021. Some aspects of the maintenance had been ignored but the owner had been meticulous about oil changes over the entire life of the car. I have been keeping a 2800-mile oil change interval based on all in-town driving. 30,000 miles later, the engine is still as tight as new. I use whatever oil is the cheapest and a Supertech filter. All dino oil is semisynthetic now. Originally, my oil change interval was 2500 miles with conventional oil.

Interesting to learn about pistons and timing belts. Funny, I never thought about the belt being lubricated by oil and that is another reason to keep the oil clean. Thank you.

[@doublebase6509]

Thank you. Just to be clear, a timing belt engine does not submerge the timing belt in oil, it’s sealed away from the oil. The crank and cam sprockets have seals around them (cam and crank seals) that prevent the oil from ever touching that belt. Then the belt is covered externally by a plastic timing cover. Oil would ruin a timing belt pretty quickly. The timing chain engines are different, the chains are submerged in that oil, and the oil is contained in the engine by a metal/aluminum timing cover. And these new timing chains are HUGE compared to old style short chains of the 80’s. They’re big, complex, and they need clean oil to keep the pins and rollers from gathering soot, which stretches the chains just enough to cause problems (noise, timing issues, misfires).

Finally! A REAL explanation to why engines begine consuming oil. I always say to use the best, longest life oil and filter I can reasonably purchase, and then change it on time. I use a lot of 20,000 mile rated oils, but then change it at half that mileage or no longer than 6 months or one year even if lots of highway miles and limited short trips. For engines that are consuming oil already and need rings and ring grooves cleaned safely, use HPL engine cleaner for a few oil changes with a high mileage synthetic, or use Valvoline's Restore and Protect oil for a few oil changes. Both of these will clean your engine safely over time and bring back a newer state to your piston ring grooves and free yp those rings

[@doublebase6509]

You mentioning HPL means we travel in the same oil/automotive circles, and those are good informative circles to be in.

A higher efficiency oil filter may however lead to more oil bypassing the filter due to higher resistance to oil flow.

@@Frank-nh9fe That is true, especially when the engine is cold and the oil is thick. I think that's why many OEM filters are so inefficient at filtering- the engineers prioritized minimal flow restriction and minimal bypass over filtering particles that are too small to do significant damage anyways. One sufficiently large chunk that gets through while the filter is in bypass can do a LOT more damage than many tiny particles ever could.

Well said, and thanks. Regarding the filters, you bring up a good point. I know there are some engines that are sensitive to bypass pressures if they are off just a little bit. I’ve never had a problem, although I certainly have used my fair share of OEM filter. I’m really liking the Fram Ultra cartridge filters for the Toyota, but I’ve used OEM more often...they’re cheaper and rated for 10,000 miles. Mobil 1 makes a decent filter, Amsoil too, but they’re expensive at $20 plus a filter. And you’re right, OEM engineers are overruled for commercial reasons, and regional warranty campaigns.

Its all down to your driving requirements. Constant cold start and short journeys add gas to your oil and so dilute it. Generally speaking, a engine needs to get rid of gas from the oil, that means long journeys. Cold engines also stress your oil and dont become hot till about 8miles. If you do lots of short journeys then your oil should be changed at half the recommended, if not more. Use your dipstick to give you a hint, if the oil is dark -change it.

Either my bikes or cars, my rule is....FOLLOW the Service manual. You will not have any issues. They even tell you when to change it in a harsh/dusty environment. Its a no brainer. I never had to open an engine ever!!!! My Cherokee clocks my oil change from 100% - 0%. Jeep says, synthetic. I change mine at 5% oil life left and its around 9K. My Goldwing says every 8K or one year. I change it at 6K cause I like higher HWY speeds. Follow that and you are good to go.

But there is evidence that the longer intervals are ok on some engines/some commutes/some driving conditions.

Regarding the oil viscosity change on the Toyota V6, I also question Toyota's advice as they likely didn't change the engine internals.

[@doublebase6509]

Yeah, if it’s saying 5w30 on the cap I’d definitely keep the 5W30 in it. Mine says 0W20 and I just bumped it up to a 5W30. I figure, it’s not that much different and this engine has been around a long time. Every search I’ve done there’s plenty of folks running the 5W30 without issue

[@SlikLizrd]

@@doublebase6509 Say WHAT !?? You say to "do what it says on the Oil Cap" in regards to the 5-W-30 oil, but then you turn around and tell us that your Cap says 0-W-20 -- but you "bumped it up" to a 5-W-30 because "It's not much different". You were right the 1st time -- Put the Oil in that the Manufacturers recommend for their Engine Oil Viscosity.

[@pliedtka]

In areas with very warm climate once the engine reaches operating temp the 5w-30 will be better at protecting engine parts than the watery 0w-20, which might be a perfect choice for real winter conditions. The fuel economy will be lower with 5w-30 due to higher frictional losses - the number one reason companies switched to very light oils to follow the stinking CAFE regulations. 0w-30 might be good alternative, I use it instead of 5w-20.

[@SlikLizrd]

@@pliedtka It's absolutely amazing -- the number of people that think that they know more about engine oils, their uses, and climatic requirements than the engineers that designed and built their engines.

I think you’re going to do well with that Corolla. I see those things with 100’s of 1000’s of miles on them, going strong. And I get what you’re saying with the 0w20/5w20...but just remember, oil is pumped, it’s not all about flow, it’s pumped under pressure and at operating temp there isn’t a big difference in viscosity at temp between a 5w20 and a 5w30. And in some countries the same engine will be spec’d for “thicker” weight oil. But I agree, the cold startups will benefit from a lighter weight oil. But I’m sure the 0w20/5w20 does great for you at all temps. I just went up in viscosity in mine (from 0W20 to 5W30) in my Toyota Avalon, but I know that the engine historically has been spec’d from anywhere between 0W20, all the way up to some heavier weights. So far so good.

You do not have to change synthetic oil once a year, when you drive less miles, or let the vehicle sit for a period. Synthetic oil never breaks down like conventional oils. Save your money doing 3k mileage oil changes. I grew up in dad's truck fleet garage, rebuilding my boat engines, and for 50 years, I DIY all my vehicle and boat repairs and rebuilds.

[@rjmari]

@@keithhults8986 Synthetic oil absolutely has an expiration. It's even on the bottle itself. Shelf life is typically 5 years. And when it's in your engine that is significantly shorter. It's not a sealed system, and there are contaminants that get into your oil over time. The detergents can only do so much, so it's a good idea to change once a year even on low mileage cars.

I can especially get away with it because, as you stated, good old fashioned carb or port injection, lower compression, NA motors just don't beat the living hell out of the oil like these modern designs do, which torch and burn the oil with even good driving conditions. I think it is ironic how things seem to be going backwards, in a way. Oil has come a long way forward, but engine design is far harsher on oil than it has ever been. Modern oils aren't just a good idea for newer designs, they are absolutely essential. Put old fashioned conventional oil in any design from the last 10 years, they will be scrap metal in no time. Put modern oils in an old engine design, you really have something that could last almost forever.

I might also try the high mileage flavor as it does seem to be burning some oil now (requiring a 1/4 qt between change or so), but I'm hoping it's just the synthetic leaking through some old seals. I had a MB and was told the expensive oil change was justified because you 'only have to do it every 10k miles'... I think that was the start of the 'interval inflation' you discuss. My Corolla is at 197k, I was going to go till 200 to change, but I think I'll do it sooner. Regarding going higher viscosity for Toyota, I heard that's a good way to clog your vvt valves.

The Lexus dealer told me I could go 10,000 miles on my Lexus between oil changes. I said absolutely not! They don’t know my driving conditions or how much stop and go traffic I sit in each day. 5,000 miles no matter what. Because I know if I did 10,000 miles and had issues down the road they would tell me I never changed my oil. Just like the Subaru dealer did to me.

4k miles on my 03 RX300 with 165k for 2 years now and 95 Celica with 301k for 12 years. OEM Toyota Filter and Walmart/Cosco High Mileage synthetic oil. 0 problems

Yeah, I think a 5,000 mile regimen using whatever brand is usually a solid formula. I’m currently trying a boutique brand and experimenting with extended intervals, BUT at the price I’m paying for Amsoil I doubt I’ll keep going beyond my latest interval. Probably head back to Mobil1 that I can usually get on sale for just a few bucks more than the Walmart Super Tech.

@@doublebase6509 I have an mt10 that I use motul every 3k miles. I doubt you need boutique brands if you drive a car normally. Can't say I do with the bike 😅

[@doublebase6509]

@@Dansk55that thing is a rocket ship! 0-60 in 3.1 seconds?? I don’t much about bikes, but for around $14,000, that seems like a lot of value packed into a high performance bike.

2GRFE are not prone to burn oil. But many 2.4, 2.5, and 1.8 L engines are if we do not do 5-8k miles /8 months oil change interval.

When I started driving in 1986 , 3k was overwhelmingly the recommended oil change interval. I know oil was not the quality as now but I’ve always stuck with the 3k interval. When I get behind of the schedule and it gets to 4k….. I start loosing sleep!

My first real new car (it was a 1999 Honda accord), I did the oil changes every 3,000 miles until I finally sold it at 289,000 miles. That’s a lot of oil changes🤣 Didn’t really help the engine much - when I finally sold it, it was consuming a quart of oil every 500 miles. Was sputtering quite a bit at idle and stalling on occasion. Removed the intake, cleaned it, replaced the EGR valve (it had failed), and replaced the IAC motor. None of it mattered, I think the rings were shot?? Not sure. I told the guy I sold it to about the issues, he didn’t care. He only paid $1,200 bucks anyway…pretty sure he drove that thing another 100,000 miles. I’m now experimenting with 10,000 mile intervals, but only because I have an easy commute (and non direct injected engine). But it does make me a little sick doing these intervals. 😂🤮

@@doublebase6509 me and wifey bought. 1995 Honda accord that was sold with 450,000 miles and still running good . My Chevy 2003 Avalanche has over 300k and no oil burn off . Quality of filters play a part too. Some stories can contradict others experiences but changing sooner than later won’t hurt. It helps if you’re doing your own oil changes as it’s much cheaper and accessible.

I've been running 10k mile intervals on my 2013 nissan altima since I got it in 2017. I run a good synthetic and a good filter. 140k miles since 2017 ang the engine is running like new. No burning oil, no leaking, no nothing. I drive uber and average 2500 miles a month.

[@edubb2491]

140k= 140,000?
