I run Amsoil 0W30. Have driven a lot on this motor oil and it still looks as good as the day it went in. Works fine in triple digit temps to 30 degree mornings here in So Cal. Never had an issue with it. I have used many brands of oil over the years and, Amsoil, works the best in my truck.

I just spoke to them about obtaining a test report. All test reports are confidential and are not for public dissemination. Sorry I could not provide more detail on this. The only thing that they told me was the M1 is aware and is not disputing the results as they also use the same labs to have this testing done on their motor oil.

Not to dig on 95ram360, but the same thing happened with him. He's talked about why mobil 1 is so great...of course that was according to a class he said he took about mobil1. I wouldn't doubt that it was sponsored by them.

According to this test, it's not that great:

The reason they tested this particular motor oil is because it's their flagship motor oil. So, they compared their best against other flagship oils made by other companies. If you note the temp of the test it's around 150º C.
Everyone assumes that it's a winter oil and, that at higher temps, it fails to protect the engine as well as a higher winter rating which, is why they intentionally chose this low rated oil as it shows that even at high temps of 150ºC (not F) this oil does not break down and provides much better protection than a higher rated winter oil.
So, if you look at the graph and all the parameters more closely, there's nothing fishy going on here. There's also another 0W rated oil in that test as well so, it's not all 5W across the board. This was intentionally done to prove a point of how their lowest winter grade motor oil shows the least amounts of wear in an industry standard test against higher winter rated, top brand motor oils as well as Castrol's top rated 0W oil.
Like I stated before, I have never seen motor oil look new after driving on it for a while. The only question I don't understand is why they don't make it more available in stores so everyone can buy it.

i found a similar chart, but it puts mobil up higher on the chart.
what would be the best protection as far as weight goes for year round use in fl? 10w40? im thinking about ordering 5 quarts of amsoil soon.
