This Just In... All 2008's must run PREMIUM!

[Little General]

I got 3000+ miles on my 08 and have run 93 since new. Found out the other day that the dealer puts 87 in for the free tank with purchase because of the cost. On top of that , this is the first new car I have ever bought that did not include the first oil change free. I read it is the same +/- engine as the corvette and all corvettes come with Mobil 1 from the factory, H2's come with dino. Since I had to do my first oil change at my cost, I put Mobil 1 in mine. I will report if mpg's change.
