10w30 in the summer, 5w30 in the winter --- the reason for that is because 5w is easier for the engine to crank over with than 10w in the winter time, because its so cold outside --- that's if you're in a cool area i guess lol. i'm from illinois, maybe you're in florida???

there's no point to running mobil 1 oil unless you've done it since the engine was new. don't waste your money. i usually use castrol, but i got some penzoil for free --- i'm not complaining

I'm a big Castrol fan too.
