Bah, that's mostly Amsoil sales hype. ;-) That link is comparing ONE particular Amsoil product to ONE particluar M-1 product. And, it's a weight not approved for use in Mercedes engines (being an xW-30, which is too thin.)
Amsoil actually buys their base stocks from Mobil and then adds their proprietary additive package. Amsoil is great stuff, don't get me wrong. I feel most Amsoil oils are about equal in performance to most M-1 oils, and either will embarrass all the Group III 'fake' synthetics (which are basically hydrocracked dino oils that exhibit some of the properties of true Group IV/V synthetics). Simple answer: If you want to use synthetics (which we've already agreed isn't for everyone and that's OK!), just buy the Mobil-1 5W-40 variety. Period. Works in all climates and in all MB engines. Under $4/qt if you don't mind shopping for it at Mall-Wart (yeah, I know, the evil empire... but we can't get the 5qt jug anywhere else.) The M-1 15W-50 is now only available as 'Extended' for more money, and IMO, it's not worth paying a premium for it. :-) -dm > ---------------------------------------------------------------------- > Date: Wed, 24 Aug 2005 12:27:34 -0700 > From: Rory <[EMAIL PROTECTED]> > Subject: Re: [MBZ] Crazy to go 20K on any oil > > Just an FYI on Mobil 1 > http://www.amsoil.com/performancetests/amsoil_vs_mobil1.aspx
