Did you look here?

or read this wrapup of amsoil's test:

This is it. Amsoil is done! The oil exceeded a year in service, with 14,000 miles on the ticker, and no filter change! Well, if the year hadn't ended, we would have had to change the filter now -- it finally reached our insolubles cap, 2,000 miles after Mobil 1. The main thing that stands out on this, our final Amsoil sample, is the ridiculous viscosity. This 5W30 oil has now thickened out to a 15W40 -- argue whether it matters if you like, but we believe engine builders spec an oil for a reason, and this oil is far, far thicker now than intended for the LS1. Switching to our flush Mobil 1 netted a nearly instant 10% improvement in fuel economy, and the engine runs a heckuva lot smoother too. To Amsoil's credit, wear metals remain in check, but we will soon see whether that was really thanks to the oil or just to engine break-in. We'll start posting detailed analysis in the coming weeks.

Next up: is it true that Mobil 1 was handicapped by an engine still breaking in? We find out!
