I read a lot. A couple observations I’ve seen that influence people when it comes to oil change intervals. I just recently read an article that said follow the oil change light on the dash. Manufacturers have spent millions fine tuning with sensors to monitor the engine. When I first got a Honda when my mother in law quit driving. It was a 2015 with 7K miles on it. I know she used the dealership for service work. No record for oil changes. It had a battery replacement and a radiator flush that was it. It was 3-4 years ago when we got it. When I got the oil changed they put a sticker in the window for 5K oil change. I asked them I thought this has a 10K oil change recommended oil changes. You can do that was the answer. My Toyota Camry has 5K maintenance, but not oil, it’s 10K My local Hyundai dealer recommended just under 4K oil changes on my wife’s Genesis. I followed it because of their warranty. No wonder people are confused. Screw it I do 5K on all but the Genesis it’s still under 4K. I have the time and oil is cheap.

Here's a sample of the millions of dollars spent on OLM technology for my newest car:

This is only the USA/Canada page of settable selections. There are about 20 more ranging from 2K miles to 12,000 miles depending on the country and it's laws. And entire selection guide for JAPAN. It is USER selectable and not hidden nor locked out. There is even a OFF function. Mine came preset to 12,000 miles or 15 months. The book has two schedules. 3,750 or 7,500 miles, time not stated. Dealer didn't even know how to change it. It isn't confusing. It's :bs:

What they do spend millions on is marketing.

I’m just relating what the average customer is seeing. When I traded my daughter the CRV for the Odyssey. I told her to do 5K oil changes. And do at least 40K transmission fluid changes. The example I used was how bad the Odyssey transmission was vibrating shifting at low speeds. Fixed with three drains and fills. Most people don’t pay attention being busy with work and kids. The light turns on they can get an oil change while shopping at Walmart. You spend what some people would think way too much time over oil analysts and research. To get vehicle life ( past 200K miles) most people wouldn’t dream of driving. My wife’s car for instance a 2011 has 140K miles. It’s drives to town everyday. Usually using 3/4 tank of fuel a week . Pretty average usage for most people. In a year at about 150 miles it will be over 15 years old it would be considered at the end of its average life. The average driver puts around 15K miles a year that equals 150K in 10 years. The oil change light will get them there. That’s why they (the manufacturers) do what they do. Follow the extreme service recommendations you’ll probably get 200K miles. Most people would cringe at the idea of driving the same vehicle 20 years daily. That’s the research that matters to them.

We're going to get into this whole "What's Common v What's Normal" thing, aren't we? :crackup:

I accept your premises that Joe Average doesn't care, doesn't want to know and for him the OLM is better than nothing. However, I cannot make that same agreement on the OEM's position. He doesn't care about YOU or Joe Average. He cares about his bottom line and that OLM hasn't got any more thought put in to it than what is required to keep you out of his profit margin and or what he has to do to limit being fined into extinction from the regulators.

I might even agree that 'some' might consider me over zealous. Just agreeing that some people think so, not agreeing to it being a fact. I consider them over trusting on the edge of gullible. Actually, over the edge of gullible.

Now to the point. I offered my last post as PROOF the OEM doesn't have some multimillion dollar plan to keep your vehicle it prime shape for your sake as you stated and what I highlighted in your post. The code behind the display isn't anything more than a clock/odometer with some arbitrary number that on some models that is even user selectable or dealer so to meet whatever regulations are in play when it gets to where it is going or the whim of the owner. There is no deep machine wear research, sensor based algorithm. Just peanut counters counting peanuts.

I goes without saying, but I’ll say it. No manufacture wants their goods to last forever. For obvious reasons. The best we can hope for is at least as long as the competition. It became abundantly clear to me when my local GMC dealer told me my truck was too old. They wouldn’t even do a brake job on it. With the exception of the driver seat it would pass as being a couple years old. We sang this song before. You’re an outlier. That suits you, that’s ok. It’s not the norm. My Honda at almost 156K miles will easily hit 200K. At that mark it will have about 4K in maintenance due including tires. I don’t need another local driver, I have two. But as a travel vehicle I’ll retire it.

If you are concerned with warranty, then run the factory suggested weight until warranty expires. I would hate to have a known issue pop up with my vehicle, and have the factory deny the warranty based on the oil that I use, whether it played a role or not. After the warranty expires, you can bypass all the marketing garbage, look at actual data, and run whatever weight you want.

As of yesterday, I switched to a 5w-30 full synthetic on my 2020, 130k mile 5.3. The engine has always ran smooth, and relatively quiet on startup, but I could IMMEDIATELY tell a difference on the first cold start with the 5w30 regarding cold engine clatter. On the first cold startup after swapping to 5w30, the engine was instantly quiet with zero clatter. It would usually take about 3-5 seconds for things to get quiet, not that the noises were ever loud. That actually surprised me as I thought my cold start engine noises would last a little longer after switching to a heavier weight oil, but the 5W30 somehow made it quieter. I'll be curious to see if there is a noise difference on startup when the weather drops into the 30's-40's this winter.

Noticed that on mine too. This is on a 600 mile engine. Took 2 vids on my phone to play back. One can tell. 0w20 sounds diesel like. Have noticed, on factory gage, pressures have kicked up around 5 pounds. It still has the same pressure on the 1500 rpm cold start. Has a slightly higher pressure on a fully warm idle in drive. It DOES have more pressure off idle when warm. When I get home from a drive, the engine sounds even better.

One wonders if GM spec`d a 5w30 for the LV3 to cover the extra noise of the counter balance mechanisms? Hmmm.

It still has the "tiny passages", "tight clearances", oil pump, AFM, VVT, etc. of the L83,L84,L86 and L87. Hmmm again.

LT1 and LT2 spec 0w40 just to really make you think...

0w20 won for fuel economy in the trucks.

Yep. Forgot about those.

LV1 and L8T get a pass too.

The LV3 wasn`t in the EPA heavy class, or the super car class. That`s why the speculation on my part.

But, I do, for obvious reasons. Yes, I'm an outlier.

Funny thing is I recently bought a 2024 RAV4. There’s an eerily similar debate over on a forum I found about not running the recommended 0w16 Toyota recommends. Guys saying it will kill the engine, “just run what Toyota says”, they say to run 5w30 in Europe, oil packages and XYZ test and ABC endorsement and blah blah blah.

I’m switching it to 0w20 to use up the stuff we have on hand and the wife’s Yukon is going 5w30. Eventually they’ll both go 5w30.

Well, you say you want them to last forever. You have at least 4. One you barely use. You have mentioned two Buicks. So there could be 5. A Honda has been mentioned for the winter to save the truck from the winter weather. So that could be six. It’s just seems kinda of odd. I have 4. One is a collector. One is my daily. One is my wife’s. The last is for trips. Non are babied, use oil, get special treatment. Just regular maintenance. Forever not a chance. I’m always looking. Life’s too short. Didn’t you just buy a new one? Forever doesn’t seem to be working out. My longest is a 2001 Acura. Next is a 2011 Genesis. What’s yours?

It does seem a little odd for a manufacturer that has a reputation for longevity. To do or recommend an oil that would decrease that likelihood. Or does it?

Oh Stan. You silly silly boy. Currently there are five on the property and what you don't know about them would fill volumes. Let me ask you a serious question. At what age did you become wise and all knowing? When did you make your last mistake? As a child I expect. Mine? As I write this I get that gut feeling its a mistake. :crackup:

Let's start simple. I don't look at 'Forever" as a destination. It's a journey and one I've been on for my entire lifetime. I have sacrificed many vehicles to the god of my own ignorance and sometimes even stupidity. But even as dumb as I can be, I'll bet Joe Average had more cars before he was 30 than I've had in a seven decade lifetime. Half or better of those were 'want' buys and not "need" buys. A few were toys like any young man has.

That journey has been both satisfying and successful. It 'seems kind'a odd' to you indeed. I understand.

In my 70 years I have had exactly two abject failures. Both times I took the advice of someone that seemed like they knew something they did not fully understand themselves nor did I. Dizzy and the wife's Paseo. Yes, imagine that. I can be fooled. Lord it is hard to be human. I understand, you've never made one, a mistake, so again, hard to grasp. And yet both of them reach or will shortly 300K miles and will go to their graves in very good shape. Both I would have and HAVE driven across country without fear or concern.

I will continue to make mistakes and I will continue to learn from them and share that experience with anyone else and more than willing to learn from theirs. Perhaps we will both benefit, eh? I will on occasion be fooled and be shamed. I will learn from that as well. It's JOURNEY Stan.

Now I understand. How can a person that makes so many mistakes give so much advice? Well Stan, it may be true that I've stepped in every bear trap in the woods. You think that I might be a useful guide so others don't loose a leg?

Read your post Stan. You've set limits on your Journey. 150K miles. Easy to bore. Affluent and don't need to care. I'm happy for you.

Know this. I've lived in your 150 mile world but you haven't lived in my 'forever' world. I just might know something useful. Then again...maybe not. If you're good there. Stay there. But let me ask this. Because you find satisfaction within your limits does that mean those that are not are broken and need to be brought back to reality? Your reality? If so, surely you can find a better set of tools than ridicule and distain to retrieve them from their error.
