Hello it’s been a while since I ran a high turbo euro direct injection car and want to ask for some advice.
Car is Audi A8 4.0 twin turbo, just installed upgraded turbos and software and about to turn up the boost, targeting 35-40psi and 800whp+.
I using German/Belgian Castrol 0w40 and live in the lovely snowy northeast (sarcasm).
Car is know for bearing wear under these power levels and I would like to improve bearing life.
Can anyone recommend me an upgrade? Should I run a 5w50 in winter and 15w50 in summer or 5w50 all year? Any brand I should look for? I used to run Rotella T6 5w40, would that be a better option? Any advice would help.
