Why 10K Miles Oil change may not be good!

Emotions
Outside of having access to a large set of data from controlled studies, this is just water cooler conversation.
Then again, that also describes 95% of the content on this site.
Question gets asked, lots of anecdotal info and a bit of data from very narrow sample pools, and we all eventually realize we don't know much of anything, and learned nothing new. We continue to make decisions based on our hunches.
Litterally this forum in a nutshell.Question gets asked, lots of anecdotal info and a bit of data from very narrow sample pools, and we all eventually realize we don't know much of anything, and learned nothing new. We continue to make decisions based on our hunches.
Edit...forgot the meme.

10k OCI (or long'ish ones) definitely not for every engine
He talks about using a high quality synthetic vs a lower quality one. But the experts on here say that if it's API certified then it's fine. So which is it? Can't have both ways. No decent independent mechanic will recommend 10k oil changes anyway. What are the low quality synthetics on the market?
He's a mechanic.
You sir, are a dying breed….or a sucker
Most people (and it’s getting worse) will tape a nickel to the car in the hopes that it makes it down the street before engine fails.
A few of you have said it already, but the owners manual OCI/maintenance items are to get you through the warranty period. After that, they could care less. YMMV.
Go take a ride in one of your VW's. It will calm you down.LOL
Let me add that if you are in a metropolitan area, your driving is "severe use". Country, rural, or interstate driving is not. So change your oil accordingly.You sir, are a dying breed….or a sucker

Yes and at the watercooler emotions wouldn't get so high.

And for every one of these junk boxes…er…Jettas there’s one that had oil consumption issues.
Although it has chilled compared to the past - people
I live 3 miles from a mountain that has a beautiful view of the Boston skyline 50 miles away but where I live is very much rural. My commute is 8 miles, averages 40mph, and only has 3 stops. Nice, constant, and easy cruising and RPMs rarely go over 2K. To put into perspective I was tracking my engine and transmission temps and engine temp is up to full operative temp within 3 miles but even on +90F days the transmission never gets above 170F. Fully warmed up it sits around 200F.

I've written about that in a few previous exchanges:

The API approvals dictate a minimum level of performance. That does not mean that some oils aren't going to perform significantly better than that. Mobil for example, limits the oxidation to a fraction of what's allowable by the API.
In reality, using an approved oil at OEM intervals will probably get you to their target service life....which is around 150K. But along the way, you may get some oil consumption and your engine may not be remain as clean as some desire. But for 95% of the public, that is good enough.
Then you have those who want "more," which would be some people on this forum. People who "hope" their engines will last 300K with internals that are clean enough to eat off of. Basically the corner cases. And that is probably where the boutique oils come in; people are willing to pay 2-3x the cost of an approved oil in hopes of making their engine last longer and run better than intended.

Absolutely, and that's really where the basic API approvals likely aim to get you.
I wasn't even referring to boutiques, just oils like M1 vs Supertech for example. Even in the mainstream, there can be significant differences in performance of the finished product depending on the internal targets set by the blender. When I was talking to Dave at @High Performance Lubricants about some of this, he remarked that they internally tested/benchmarked Mobil 1FS 0W-40 and he was blown away by how good it was, let alone at the price point Mobil sells it.Then you have those who want "more," which would be some people on this forum.

The slides I posted from Mobil in one of those linked threads illustrates that too, even relative to their own products that "meet the spec", their Mobil 1 product offerings are held to a higher standard for performance.
So, I'd say there's some "truth in advertising" with regards to some of the claims from Mobil and Shell about their premium offerings and the performance they provide.
I just maintain my vehicles because I never know when I'm going to get rid of it and don't want it to break down on me while I own it. Last car I spent several thousand fixing it so that it was fine and then dumped it a year later.
You don't need to hang yourself, just get rid of the '99 Corolla although you could wait 6 months to a year to see if used car prices come down more.
