Idk about you. I wouldn't use 5w20. Since the car burns oil like a b*tch, I use 94 octane gas instead, along with lawnmower oil (it burns clean, no deposits). I fill with 91 octane into the tank. You should try it, it works wonders.

Owner's Manual ;)

I ******* lol'd my way through all 4 pages!

BEING THAT HE'S IN TEXAS what about the manual recomendation for 10-w30 in warmer climates? (sorry caps lock was on and i don;t feel like fixing it)

5w30 forever
