What brand of Motor Oil do you use?

[verothacamaro]

Amsoil.....the best synthetic oil. ever.

it's worth the price, especially if you can change the oil every 25,000 miles.

[verothacamaro]

If you're interested, I can get you Amsoil stuff.

I run the EaOil filter in my vehicles. Its rated for 25k miles. Quality filter.

you know whats good......are you a dealer too??

[smokeeey420]

Royal Purple

Yes, but I use the "dealer" title very loosely. I don't pound pavement trying to sell the stuff. I have friends that want, so I sell it them. If people want it, I'll sell it but I won't push it on them.

I really like the stuff a lot. But if there is something out there that is better, I'll use it. Fuel additives, engine additives are some things that aren't Amsoil I use.

Thats bad ass lmk how much you can get the filter for. Didnt know they can last up to 25000 miles thats pretty damn good. Saves me money lol.

I was thinking of making a thread like this one, and realized that one already existed. I even voted in the poll; who knew?

Anywho, I'm still a fan of Quaker State, but now I'm a die hard Mobil 1 type of person. I also like a few others as well, but my first go to oil is Mobil 1.

I use Schaeffer 9000. Good shit. Seems to produce better breakdown numbers than Royal Purple.

Haters gonna hate lol.

Well since someone already bumped the deadest thread I've seen lol, I run Shell Rotella T6 5w40 in the STI, and will probably run that in the RB once its done, was going to run royal purple until I found it it's quite possibly one of the worst oils ever, and Mobil 1, Valvoline and other such oil suck in turbo engines, if I had decided to use Mobile 1 in my STI just after 2000 miles it would of sheered down to 5w20 from 5w30..yeah no bueno.

[CB7DX420]

I just did a Royal Purple HPS 10w30 oil change today. I've always like Royal Purple
Only other oil i like is Valvoline VR1, again in 10w30.

[SOHC-FTW]

Amsoil, Rotella T, Castrol.

[Tippey764]

Whatever is on sale at advance auto uses its Quaker state.

[oni_cb7]

I use Chevron Delo 15w40. amazing oil.

For all of you recommending your favorite oil, what are the bases of your recommendation?

Is is based on your butt dyno, feeling?
Is it based on engine tear down and taking measurements before and after?
Is it based on how it looks inside the engine?
Is it a price?
