Daughter just purchased an 07 Camry LE with the 2AZ-FE 4-banger with 84k miles from individual. Don't know maintenance history of vehicle. Had my mechanic look it over and said tranny fluid is getting old. Was going to do several drains and refills with Maxlife, but I'm undecided about engine oil. My research on 2AZ-FE indicates it can become an oil burner if not maintained properly because of plugged drain holes in the pistons. Toyota went to 0w-20 or 5w-20 recommendation for 07. Previous models used 5w-30. Oil on dipstick when purchased was above the full mark, which leads me to believe whoever changed it last just poured in 5 quarts instead of the 4.5 quarts needed to hit the full mark. What would you do for first oil change. Try 5w-20 and watch for consumption or go ahead with 5w-30. I've got synthetic or syn blend in both. Also have some Kreen if anyone wishes to chime in on that application.
