what weight oil should i use after 100,000 miles turboed? im pretty sure the motor is beat but what would be my safest bet on oil?...im thinking 10W30

 

15w50 BABBBBYYY!!! Nah jk lol Is it burning oil at all? COmpression test? If its a tad low compression and burning a tad of oil - run mobil 1 10w40 high milage - just noticed youre in delaware - well id run the 10w40 himi in the summer and like a regular 5w30 in the winter when its below freezing

 

im using castrol syntec 5w30

 

keep the same oil
