Why 10K Miles Oil change may not be good!

I've never changed the oil in my Toyota in less than 10k miles. I've gone as long as 18k miles.
I've had my 2007 Toyota FJ Cruiser with gasoline 4.0L V61GR-FE w/DOHC and VVTi. It is my daily driver and has been for almost 14 yrs. Engine has 220k miles. Its never burned or leaked oil. Its never throw a code or been in a shop. I've posted its 13 UOA report results here on BITOG. Owners manual says to change it every 5k. What a waste that would be.

No timing chain problems? Ours is getting noisey

The thought's crossed my mind, but I'm afraid a W40 would bog down the small 4 banger.

I’m 1600 miles into my oci with 0w40 in my 2017 accord sport and it runs just like it did with w20 and w30. Knowing it is just a thick 30, I figured I would give it a try. Gas mileage is still the same.

If you would have taped over the grade and I poured it in, I would just assume it is a 20 or 30 grade from the way the car still runs like normal, if that makes sense

So, with the API SP rating, is there really "Dealer swill" out there? Wouldn't even the cheapest API SP oil (or even SN) still be fine for a reasonable OCI for most cars?

I mean, we're Unicorns here. What percentage of the population reads BITOG and thinks about the oil in their car? Unless I'm wrong, it's probably waaaaaaay less than 1%. Lots of Jiffy Lube stickers in the parking lot where I work.....

Well, there have already been questions raised about SP not being as durable as SN/SN+, and I stand behind my “dealer swill” statement-was forced to use dealer bulk from a Ford dealer (NOT Motorcraft) of an unknown brand, which the Transit 3.7 went through like water, costing a $2500 set of cats at just over 100K. MaxLife essentially stopped the oil consumption, but the damage was already done. OCI was 7500 (company decision, not mine). The moral is-if you don’t do any UOAs, and use unknown bulk, run long OCIs at your own risk!

If you ever decide to sell the FJ, don’t tell any prospective buyers about that OCI history. I wouldn’t walk away, I’d run.

Engine looks flawless except two gummed up rings. Is there some sort of design flaw?

Is 10k even the factory interval for this engine? It seems a bit high for Toyota.

All Toyota’s that spec 0W20 and 0W16 have been on a 10K schedule since 2010.

I few yrs ago I bought a 07 FJ TRD w/230k miles from a friend for cheap just to flip it. It had noisey chains that why I didn't keep it.

I don't think ours had the best maintenance before we bought it. Seems a little dirty when looking down the oil filler hole. If it sits a couple of days the chain really rattles when first started. Enough to worry me but it has not thrown a po16 code yet.

Oddly the orang can of doom filters seem to hold the oil in them longer than any other brand which lessens the rattle a lot. The Toyota filters were by far the worst. Completely drained over night.

Oil change intervals for Toyota have been 10,000 miles on many if their vehicles across their fleet for a while now.

And you bring up a good point about this engine and these rings, as far as I know there is a design flaw. It’s the drain back ports in the lands on the control rings. They’re too small, I believe the revised pistons have a different design with larger openings. There is a video on it on YouTube (I believe). The guy points out the openings. Not sure how legitimate the theory of those ports are, but there is certainly oil consumption/stuck ring issues with these engines.

There is also more than one video out there about this engine...the oil consumption, the oil rings, engine replacement or piston replacement (if the block isn’t damaged). Usually it starts at 120,000 and then gets worse to the point where piston replacement is needed.
