so i have a 2006 scion tc with a turbonetics 57 trim. i need to do an oil change and am gonna do it tommorow. this being my first boosted car what is the best synthetic oil to run...... viscosity, weight, and brand. i usually run RP in all my cars but i was reading about a kid that asked the same thing about his 03 protege turbo and the factory says 5w30 and the forum recommended 0w40. they said it would provide awesome turbo protection and its will flow fast. is this what i should run too?

 

paul from dezod told me to run 10w40.....i run royal purple and am thinking of going to rotella if they make a 10w40

 

I'm running 10W30 right now.

 

mobil1 10w30

no problems
