what synthetic oil do you guys use in the summer
 

I'm sure I could stfa but the forum is dead anyway so wtf are you guys using? :p

Depends on the conditions and set-up.Higher oil temp=thicker oil.Under +200f you could even use a 30

does brand matter to you?

Mobil 1 0W-40

that works for me, I'll go with that

M1 5w-30 or 5w-40TDT

ok. I live in Vegas and it's going to be 100 degrees soon. I have a 1.8. ...
 

with GIAC software, bigger injectors(if that matters). What do you think would work better for me?

TDT, best oil that's readily available

I hope I can find that locally. If not gotta go with Mobil

it is Mobil 5w-40 TDT from wal mart
