I've been using valvoline for years in all my vehicles. I am suprised by MOBIL 1 results, it comes highly recommened.

The load test is a very minor representaion of the properties and capabilities of an oil. If one was to simply use lithium grease as a test subject I would suspect the results to be superior....but not for a motor oil. Many other tests must be conducted to determine an oils suitability for use in an engine. I suggest you visit the bitog site (bobistheoilguy.com) before accepting this very limited test as an accurate representaion of what quality motor oil is.

I agree that it's only one test. In particular, it doesn't tell you much about long drain oils.
What does tell you though is all the people like myself running a full sythetic (I use Amsoil, which they didn't test because it wasn't available a a local sture) who have good oil analysis after 20,000 miles or more. That's the interval between oil changes for me (19k to 20k) and my results have been excellent with very, very low wear metals.
Amsoil, Royal Purple, and Mobil 1 all use the same synthetic base stock and what distinguishes them is the additives.
One note: the API certification REQUIRES certain additives and ratios regardless of whether newer materials might be as good or superior. This actually results in a potential "built in" limitation on API certified oils -- they are all handicapped by the same "standard".
Still, that was a nice article and a good additional reference about oil in general.

Just my opinion.

Most Amsoil isn't certified either. You're right on in your comments. If they use non-API ingredients, they can't pass certification and Amsoil and Royal Purple have opted out of that particular trap.
If you read my post carefully, you'll see I do just exactly what you said. Based on actual oil analysis, I'm totally comfortable running a 1 year drain interval.
