amsoil has the 4-ball wear test results to back up their claims.
if you don't like the fact that the results is on their website, i'd be glad to see a 4-ball wear test result comparing amsoil with other oil that is posted or done anywhere else...
until then...

When I bought my 350z last year, I joined my350z.com and they had a thread with oil that was sent in to blackstone for analysis. It was pretty amazing the results because everyone was using all types of oil and surprisingly the best one for the VQHR engine was Castrol.
It would be nice to know what brand would be ideal for the s2k engine.

never said it was...but it is an indicator.
How soon we get sucked in since that great Duralube "ball bearing" test that was debunked so many years ago. 
Yeah, right. It's an indicator ............ of great marketing!

What is the Four Ball Wear Test? How good a predictor of engine wear is it?
The Four Ball Wear Test puts one rotating ball against three fixed balls under specific conditions of pressure, temperature, revolutions per minute and duration. The test may be used to evaluate the friction- and wear-control ability of liquid lubricants or greases in sliding contact. The Four Ball Wear Test is a good laboratory tool for developing oils with good engine wear control.

Significance and Use
The four-ball wear-test method can be used to determine the relative wear-preventing properties of greases under the test conditions and if the test conditions are changed the relative ratings may be different. No correlation has been established between the four-ball wear test and field service. The test method cannot be used to differentiate between Extreme Pressure (EP) and Non-Extreme Pressure (Non-EP) Greases.
1. Scope
1.1 This test method covers the determination of the wear preventive characteristics of greases in sliding steel-on-steel applications. It is not intended to predict wear characteristics with metal combinations other than steel-on-steel or to evaluate the extreme pressure characteristics of the grease.
1.2 The values stated in SI units are to be regarded as the standard except where the test apparatus or consumable parts are only available in other units. In such cases, these will be regarded as standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

I used mobile 1 at my last oil change and this time, when I drained out the old oil, the pan was almost empty. I never noticed any oil burning/weird looking smoke/etc... Then app. 3 days ago, I randomly checked my oil, and it was up above the max. fill level... I clearly remember draining every last drop out of it, replacing the filter, then refilling it with the manual required amount of 4.1 US Quarts, done. The oil was also really dirty looking... I'm going to try and use the new valvoline next time... any opinions??

Duralube fudged those tests. Any test can be fudged, no matter how "official" it's made to seem. It's gullible people who stand by their authenticity. That's what make good marketing so much fun and profitable.
Amsoil all the way!
