What brand of Motor Oil do you use?

Supertech,mobil 1 , or royal purple(when money burns).

I choose Royal Purple because in my last 2 civic's i used it and each oil change i changed the valvecover gasket for 2 reasons;
1) to keep away leaks
2) to see how the valvetrain looks

Both of my civic's heads upon inspection were in such nice condition it surprised me, and I beat the living shit out of those engines everywhere i went it was WOT and redline! So being that they looked clean under the cover even under constant harsh conditions I chose to stick with RoyalPurple.

i use royal purple simply because of good experience with it

OEM Honda Full synthetic 10W-30 I find that is has the slowest burnoff rate of any oil Ive used. Quaker state burns off the fastest of oils I have used.

10w30 Mobil 1 full synthetic.

I first started using that stuff when I noticed back in the 90's that a lot of OEM performance cars came factory equipped with Mobil 1 full synthetic.
