Piston ring cleanliness.
The great BITOG conundrum.
I am going to bring this up soon,
at an important business meeting near Chicago.

Across all US models VW recommends 1 year / 10,000 miles. Both my wife and I and my MIL own MKVII Jettas. I change our oil out every 5K whereas she runs all the way out to 10K / 1 year. She just bought out the lease and seems to be ready to own it long term. So we will see how things play out.10K miles for OCI, who does that!??
early OCI is a lowest cost of insurance for durability and longevity of your engine
the same goes for your food, everyones likes fresh ingredients or food at the dining table so the same goes for car fluids
again, change your oil early
And many run to 200K without issue.API exempts 0W-16 and 0W-20 from the TEOST 33C Hight Temperature Deposit test. I don't find it a coincidence that may engines(especially Japanese) running 0W-20 end up oil burning POSs due to gunked up rings.
See page 11 of this document to confirm:

that was funny when he attacked ChrisFix, then apologized, all the while ChrisFix doesn't even acknowledge scotty's existenceThe best answer is "What would Scotty say?"
I've changed at.less than 3k miles, but at about 7 mos. I've been on a 6 month, 5,000 mile schedule since purchasing the car. I think I'm OK with your scenario, but I'd definitely want to use a high quality oil if stretching the OCI to a year. An oil that "meets the specs" would never be in the sump under those conditions.Brings up a interesting point though. 6month/5k. How do folks feel about annual oil changes and less then 3k miles?
I was just going to reply that all we need now is a video link to Scotty Kilmer. Lol.The best answer is "What would Scotty say?"
I've been changing oil and filter every 10,000 miles since the year 2000 when I bought my first used Lincoln Town Car. I've now owned several TCs and run each one about 150,000 miles. None have ever used and eyedropper's worth of oil between changes. I've always used CAM-2 5W-20 100% synthetic, and I'm dismayed that it's no longer available. My current TC is a 2006 with 145,000 miles on it, and I'm about to do an oil and filter change. Gonna try 0W-40 European Formula keeping my eye on it every 3000 miles till I see whether it's as good as my CAM-2~!10K miles for OCI, who does that!??

He did mention in the video that customers assume dealers are using Toyota oil. He said some dealerships use the cheapest oil they get.The interesting bit was what he didn't say...what oil was the dealership using at 10K OCI?
No visible sludge or significant varnish in the engine's splashed or washed surfaces, oil control rings were completely immobilized and cylinder wall was worn. Bearing shell he showed had no visible damage. Strong evidence that they were using synthetic oil of some brand. But was it a low-end oil brand? Could TGMO or other reputable brand have prevented this at 10K OCI?
Seems like the oil was cooked at the piston...I'd love to see pics of the piston undersides and I'll ask on his YT channel. Did the oil sprayers in the block clog up (but with what given no visible sludge)? Is it another case of Toyota pistons clogging the oil holes in the ringlands?
Impossible to judge the cyl wall damage, but I really wonder if the oil control rings couldn't have been unstuck with Valvoline Blue Restore oil or something similar...
A Lincoln Town Car is going to be different than a Camry that only holds 4 quarts of oil. I would also think that the Camry would rev higher and be driven harder than a Lincoln Town Car.I've been changing oil and filter every 10,000 miles since the year 2000 when I bought my first used Lincoln Town Car.

6 months more like 6 years….it’s not 1922 anymoreIf one is changing their own oil with a high quality oil 10k/6mo OCI may be fine.
Perhaps. We drive each car about 20k miles/year so we hit 10k miles before 6 months. Maybe 10k miles / 12 months would be fine. Never really been in that place.6 months more like 6 years….it’s not 1922 anymore

I'd think the oil and filter would be loaded with dirt by 10K.My wife's Mustang sees about 20k miles/year as well. Therefore, we use an oil that's good to 20k miles.
