Venting Local Toyota Dealer

All the fluids are lifetime, you will be sorely disappointed by the life span though. That 10k interval has every caveat under the sun listed. Nonetheless used oil analysis has shown it's possible. It would be nice if Toyota had an hour meter for an additional point of measure, even lackluster GM has had that for decades.

A simple comparison - 10,000 miles at an average of 65 mph is 150 hours on the drive line. At a 20mph average that same 150 hours is 3100 miles. That is not even factoring in the higher oil temps typical of city driving.

 

Starts to pay for itself after about 3.5 years (if you planned on taking to dealer for your oil changes) not a horrible deal if you plan on keeping the truck.
