Who uses synthetic motor oil in their WRX?
Its almost time for my first oil change in my WRX and i was wondering if I should use synthetic motor oil or just stick with regular motor oil, or go for a synthetic blend?
What do you guys use in your cars?
Thanks,
Zoeb

I waited till 3000 miles to change mine to synthetic. I ended up using 15w 50 tri syn from mobile one. I had about 15000 mile on the engine when i had to tear it apart. When i opend it up the cylander walls and everything looked brand new. Keep in mind that most of the 15000 miles were spent at auto-x road racing and street racing running nitrous. Just my 2 cents.

Why 15w50 and not 5w30 or 10w30? That oil is so heavy. And what does the tri mean in try syn of your above quote?

I switched over to full synthetic after 3k. Not much difference from what i can tell. From what i read at the other site though is that synthetic resists coking more than dino oil. hope that helps.
oh yeah, i'm running mobil 1 5W-30. Costco has it for like $26 for 6 qts. Cheapest place i've found.
