When the engine is cold the oil is 10 w. when it get hot it's 30 w. That means that 5 is better then 10 w cold.

Unless you have a turbo or supercharger or live in climates with extreme temperatures, a quality dino oil is fine. You don't need additives. Just change the oil and oil filter every 3,000 miles. Save your money for mods.

LOL!! That's what I'm thinking. I managed to get them to throw in a 3 year "essential care" package but, like you said, they use regular oil. I haven't taken delivery of my car yet and I'm debating on what to do. seems to me, they'd probably dump the regular oil in your car and fill up the empties with the Mobil 1 and take it home!

I think he was talking about heat being the problem and not cold. He lives in the warm climate (nevermind me, I'm just jealous).
