Anything from 0w30 to 15w50 (in the summer) seems to work just fine in our cars. The 15w50 is a little thick... but should be a little safer in the heat. On the other hand, I've been told that the 15w50 will actually generate *more* heat because it's so thick... go figure.

Either way, Mobil1 10w30 or 5w30 should be great in your car... it's not like your motor is seeing extreme conditions like endurance or drag racing.

That said, I use 10w30 RedLine in my car when it's working right, and Mobil1 5w30 or 10w30 (whatever WalMart's got in stock in the big cans) when I'm leaking lots of oil (since it sucks to waste $9 per quart that ends up in my catch cans).
