Database Error On my other thread please delete, So the Cobalt has 4xxxkms on it now, iam getting an oil change shortly. I have the SS/SC with stg2,2.9,and cat back. Which oil should i use? Iam not cheap on oil either.

 

Mobil one synthetic 5w30 is what i use and i think its recommended and what i believe comes in the car stock. I've got stage 2, 2.9, ported blower, full exhaust and intake.

 

Royal Purple 5w30 syn. FTW!!!

 

real question is, would you rather use Royal Purple or Mobil One?

 

mobil one. That is what GM recommends, and that is what the car comes with from the factory.

 

Rp is gm certified (sp)

 

Royal Purple

 

Mobil One

 

dont use royal purple...or mobil 1, go with AMSOIL!!! def the best money can buy

 

is it gm certified? That is the question

 

Royal Purple FTW!!!

 

Royal Purple beats all the competition in every test anyone you have ever heard of has done. It's win/win.

 

You're a fool if you use Mobil 1 over Royal Purple

 

yes it is and AMSOIL outperforms royal purple and mobil1....no question the best oil on the market

 

Mobile 1

 

royal purple

 

x2.

 

Mobile 1 Syn

 

walmart 10w30

 

Mobil 1

 

ive used mobile 1, valvoline, and this "ENEOS" oil... i thought of tryin royal purple but i really like this eneos brand... its supossedly a really high-end japanese race oil and it actually looks and smells different than the others.. that really doesnt mean anything but theres obviously something different about it and really like it.. engine seems to run way smoother... you should def check it out..

 

i cant use rp just because they add some tint to make there oil purple, i cant get over it. im not saying that rp sux, im just not comfy with it.

go amsoil 5w30, but stay away from there racing formula
