I agree with the benefits of synthetic oil. After break-in of my autos, I have changed all to Mobil 1. In each case I noticed at least 1 1/2 mpg increase and better operation. I do think it a waste of money to change oil at 3000 miles in any fuel injected car (or others too) because they don't get contaminated as in the past. I will usually change filters at about 4000 miles and oil 7000 to 8000 miles and the oil I remove looks clean and feels slippery (technical word). The manufacturer states 7500 or so on oil changes.
I know some of this has been stated before but had to my 2 cents. I will run Mobil 1 in my '32 roadster after break-in and I use Mobil 1 in the rear and will also use a synthetic in trans.

P.S. I understand the new 'Vettes will not be warrented if you don't use Mobil 1.
