what weight oil are you guys running? my friend with the turbo zx2 is thinking of running 15w50....is that too heavy for a zetec?
5w30 Mobil 1 for me

I was running 15w50 Mobil 1 when I was doing the turbo, it seemed ok. But then again it could have been the reason for my oil drain problems too.....
we run 0 weight but 5 weight oil is fine IMO

what kind of problem specifically?


whers flo? im interested in what hes running too
you may want to go slightly hgher weight with a turbo to keep oil from leaking past the seals... superchargers can use the same weight as stock.

I don't think 50w is necessary unless you're like turbo tom going for super high numbers (thicker oil also raises cylinder pressures too).
5W30 synthetic
thanks guys, i will pass this info along to my friend.
Powerworks recommends 5w30 synth, we run Royal Purple in all the boosted foci we have touched.
I try and use CLEAN oil it weems to work best for me :lol:
