And for every one of these appliances...er...Camrys there's one that went longer without any oil consumption issues on long 10K runs...your average person probably forgets to change it once in a while too...opppsies! 10K with a v. high quality oil (I'd say the oil is more than likely the culprit) for the the highway commuting the video talks about seems v. reasonable to me. Did that in my MK4 Jetta with M1 0W40 10K changes for a big chunk of the 220K highway commuting miles it had when I sold it without any oil consumption issues.
Why 10K Miles Oil change may not be good!

The third option and maybe I'm a sucker for feeling this way is when someone buys a vehicle from me, while I offer no warranty, I do try and sell that person a vehicle that was well-maintained, even if that means I spent a couple of hundred dollars more on oil changes over my period of ownership.
The peanut gallery is awfully quite now, that said I plan to do a UOA on my current fill of HPL 15w40 in the crown vic every 5k miles until the oil comes back as needing changed after a few times of doing this I’ll be able to do a UOA at 10k miles until I dial in things a bit more, the plan is 20k mile OCIs
if the car is deemed in great condition, I normally pass it along/sell to someone within my vicinity instead to a random guy or a dealership

Let's all be honest with ourselves.
1. The car we have always wanted in our garage is a 1999 Toyota Corolla. Preferably a CE with roll 'em up windows.
2. We know that by keeping the rpm below 2250 and driving with a foot lighter than a butterfly wing, we can make that Corolla last forever with a 10k OCI.
3. Everything we do maintenance wise is perfect. We coast to a stop. Always have two hands on the wheel and time our acceleration so that we maximize our mpg.
4. Also one other thing. Anecdotes and opinions aren't credible. Facts and data from impartial expert sources are. That's why everyone is reading this from yours truly. I'm Steven Lang. Although I don't have the facts or data, I know those who do. Those are the engineers who spend their lives studying chemical engineering and applying it to God's greatest gift to mankind.
And those would be the wise omnipotent souls who developed the 1999 Toyota Corolla.

**** with all these oil burning problems people having . It’s time to go back to the Jiffy Lube special 3months or 3,000 miles
Reading this and thinking of driving a '99 Corolla in this way makes me want to hang myself.
Don't do it! LIsten to me! Just take it easy, ok?..........just put down the keys 
, everything's gonna be ok. 
, everything's gonna be ok. Add supercharger, then you can smoke the other Corollas between red lights. Think of the fun!
The Toyota guy keeps saying 5K or six months. I can maybe see once a year for low-mileage cars but every six months? Does it really go bad that quickly?
like toyota says
rack up
rack down
it’s still not an excuse for an unnecessary LOF job
i detect sarcasm, but I cant tell. Especially since the 99 corolla 1zzfe was notoriously bad for oil burning issues (needed more oil return holes that were either implemented with the DIY bennie fix or updated pistons). 10K oci is wild for that vintage of rolla
Is the API standard useless as a marker of oil quality in relation to how long it can work whether measured as factor of time/mileage?
The MM on my Grand Caravan will go off at around 7500 miles for our driving style, which is mostly short trips, but I still cannot bring myself to follow it. 5k OCIs for me please.
I have extended our OCI since coming to BITOG but I didn't do it right away. It took me some time to get past the 3mo/3K OCI.
Now I just do it twice-a-year. And the OCI could be anywhere between 5K-7K miles depending on how the vehicles was used during that time.

My understanding is that it's a minimum standard. That, in part, is why I use the higher level M1 oil, and why I'm going to the HPL meeting. At least API is a reference point, but some of the acknowledged better quality oils don't have API approvals. That's something to think about.
We’ve beat this Toyota video within an inch of it’s life if not to death already.
Not very high opinion of Ford video poster… frankly do not believe that piston is out of an 18,000 mile motor with actual 5000 mile changes .

in a tdi engine like my Honda never....
in my vibe with Toyotas 1.8l mpfi perhaps under the right conditions...ah heck never have done 10k probably never will...I like 5k shoot me...

So that engine in the video looked fine/really clean everywhere else but rings. I wonder how the rings would have looked with the use of a flush product such as LM Engine Flush (or running the HPL EC) at some interval maintaining 10K changes? Could fuel quality have any impact? Would 5K for sure have prevented this? Would a higher quality oil (what is "higher quality") have prevented it at 10K?
