I am reading this document and very surprised to find out that the Toyota recommendation for oil change is 10000 miles. Are they really that confident to their Turbo engine, or they just encourage everybody to wear off the engine pre-maturely? I was thinking changing oil half of recommended schedule (5000 miles for normal condition and 2500 for rugged driving environment)
What do you think is the other maintenance items that you would perform beyond manufacturer' recommendation?
