really just days? i need my motor to last years not days

 

Maybe I'm not as geeking as all you, but I've ran Royal Purple, Mobile 1 and Redline 10w30 and have not felt, seen, smelt, tasted or heard any difference between the three. Just go with the cheapest out of those three, non of them will hurt your street car .

oh and 40wt race oil in a street sti... at that one.

 

i'm just kidding anyways i don't really want to spend the money for redline anymore since i'm not really that hard on the car and mobil 1 has proven results of not popping motors with 3k changes

 

Let me know how this is funny and I will laugh with you.....

 

I just had my 30k done at GST and they recommend as well as use Mobil1

 

5w30 yes?

 

5w30 is fine unless you're beating on it on the track or driving it hard in the summer at 90+ deg temps, then you should consider maybe going up a viscosity grade. just my humble opinion.

heavier weight does have side effects: lower mileage and less horsepower

 

Why do you want/need to run 40wt race oil in your street driven car?

 

Supertech Ftw!!!

 

sorry for the noobness but ... whats the difference between 5w30 and 10w30?

 

oil consumption and heavy modifications (imo)

 

so, where in dublin/pleasanton should i get my oil changed?

i'm only at 11.5k

 

old thread but

A lot of evo guys are switching away from M1 too, even though it says to use it right on the oil cap. The current M1 isnt the same as it was a few years ago. I use quaker state Q horsepower full synthetic now. $20 a jug at walmart ftw

 

GC 0w30 ftw!

 

the same Quaker State Q with an STi on the bottle and in the commercial? lol
