Hey, Welcome!

10w-30 Castrol, but use Mobil 1 if you can. The previous owner in my car had been using organic, so I had to stick with it.

Welcome to the forum. Castrol GTX is the oil of choice for me.

Just make sure you use the weight that is recomended by the factory. I got my '04 just a few months ago, and the dealer made it very clear that if I use the wrong weight oil, it would void the warrenty... not sure if that's true, but I won't chance it...

Well according to the oil cap 04 should us 5w-30 but the owners manuel does say you can us 10w-30 as well depending on the time of the year >>> I personal use castrol GTX ran it in the 91 for 8 years and never had a bit of trouble out of it

i run 3 quarts valvoline and 2 quarts lucas heavy duty stabilizer. keeps metal parts lubed a thousand times longer than conventional oil, plus eliminates dry starts,even after a month or so! my girlfriends dad couldnt get the slickness of the stuff off his wrench for over a month! but it might not be under warranty specs, but it sure as hell has my vote. i use 10w-30

Waste of money StangTangGT.

Any brand synthetic oil will help avoid dry-starts.

I use Castrol synthetics. Last fill I used Texaco Synthetics.
