I have a 03 wrx 2.0turbo with 4k on the motor. I've been told Mobil 1 breaks down to quickly I was just wondering what kind of full synthetic I should run? At the moment I have valvoline vR1 non synthetic oil finishing up the break in period. Thanks!

 

I think most here will throw out to use Rotella T6 a.Im going back to Castrol only because i cant seem to always find Rotella and it only comes in the smaller jug easier for me to just get one jug of castrol and be done.

 

thanks! One of my buddies said castrol 1040 diesel oil but I didn't know about that
