FI Z's what Oil are you using
 

I just wanted to know what everyone is using. I don't care what brand because everyone has something to say about Brand A vs Brand B so lets limit that. Put in the brand if you want. I just switched to a heavier oil and man what a difference i can tell. I don't know if im trippin or if I can really feel the difference with a different weight oil.

Was running 5w 30
Switched to 10w40

Feels awesome.

Oil
 

M1 0-40! Year-Round

Major, Yuma Arizona

15w50 Mobil 1 , only run summer...

considering thinning up my oil a little tho after puting in my large oil cooler, concerned with additional stress on the oil pump.

Mobil 1 Full Syn 10W-30 year round.

Considering a switch to Turbonetics oil though. After reading their article on it it seems pretty good. Then again I'm paranoid about my car....

I'm using the Turbonetics 5w-30 that came with my kit.

Valvoline VR1 SAE 40.

+1 (although not certain on the weight)

Turbonetics 5w-30....Came with the kit. I'll probably use Mobil1 at the next oil change just because it's readily available.
