quote:What impresses me is the low NOAK of 5.5% and the HT/HS. Mobil 1 0w-40 is 3.6 vs 4.2 for this oil. Flash point is higher with the AFL, but the 0w-40 is as high. However, the SUV equivalent, is 4.1 HT/HS NOAK unknown. What I'd look out for is whether this Amsoil thickens or not, which seems to be a problem at times.

Sorry, but I think Amsoil is a day late and a dollar short with this oil.
quote:Mike, a 5W-40 or even a 0W-40 won't get a starburst anyway !! M1 0W-40 doesn't have one either. Only energy conserving viscosities get that, and Xw-40 oils are not in that class.
Originally posted by Mike Thompson: For the US market? I don't see the starburst.....as long as Amzoil refuses to certify, they'll not be a big player in the US. If some of the big-market, certified oils didn't have to follow the rules, as it were, they would probably have better specs. Mike

quote:Well, a "new" oil designed for European cars should be in the "newest" grade that said European cars are getting. Virtually all European cars sold in the US don't come with 5w40 in the crankcase. Porsche, Aston-Martin, and the AMG Mercedes models come with Mobil 1 0w40. Standard Mereces-Benz models come with 5w30 synthetic that meets 229.5. All BMW engines (except for the M3) come with Castrol/BMW 5w30, though it now appears that BMW is switching to 0w40. Volkswagon/Audi may be the only cars that actually do come with 5w40, and that's probably just in the W8 as well as the W12 in the upcoming Phaeton.
Originally posted by Pablo: G-Man I disagree. Maybe late to market, but Amsoil doesn't market Europe. So late??? A dollar short? Excuse me, but I think they purposely avoided the 0W- ,which doesn't sell in the USA worth a hoot, other than folks here. You maybe miss the point - the oil is for the US market. So a GOOD synthetic 5W-40 choice is great news. It'll be in my newer Volvo, which now has 10W-40.
