9854-mile used oil analysis, oil change thoughts

yes, i have a hard time watching his long winded videos, which most videos are. i'd rather read a report

 

The longer the video the more you tube can put ads in between. Can’t make money with short videos on youtube, single ad won’t bring enough revenue

 

I found some other videos that go more in depth and give better details.
Edit: I think when it comes to oil changes, do whatever you’re most comfortable with. I personally think if you’re consistently driving highway or longer trips you’re completely fine to extend the oil to 7,500, or even further. I’ve had no problems from doing 10-11k oil changes for the first 140k. I personally stick with 5-6k miles now just because I want to keep this car as long as I possibly can.

Breakdown of a Toyota engine

very technical videos:

 

Don’t do any oil testing and change the oil at 5k or less seems like a simpler way.

 

Oil test takes less than 3 seconds to grab a sample for anyone. A lab coat person is not required to be present to do the work with pipets and swirling flasks.

 

Are we ignoring the fact that these cars will pass these oil test and still clog the rings? These oil test don't catch ring issues.

 

I'd, also, be interested to see oil lab analysis after 10,000 miles of an engine run on the cheap, bulk oil the majority of car repair and even Toyota Service departments use. (Yes, they use OEM filter, NO they do not use the Toyota oil...I've asked numerous Toyota mechanics and service departments...if it's wet and slippery, they will use it.)
I, also, change our Toyota's oil at 5,000 miles or 6-months (whichever comes first, sometimes that's only 2,000 miles). For our non-Toyota cars, they get changed every 3,000 or 6-months.

 

I also own a lot of vehicles and things that need oil changes. Here I do 5k or 12mo oil changes. The oil gets pretty stick with time as well. I find over a year will leads to getting down right sticky. 12 mo or less is doing pretty well.
We changed one one time on a barn find car that was parked for 7 years. Oil was basically molasses.
