Hey guys- I bought an '04 in Sept. and when I asked the dealer if the engine came with Mobil One from the factory he said yes, but you know how dealers can say anything you want to hear. I know the Vette comes with it and since it's due to be changed before winter storage thought I'd ask somebody who knows. Didn't see any M1 sticker under the hood. Thanks for any advice, and NO the car isn't brown!!!
