Hi,
Pablo - You should read the last few UOAs. The shearing issue is largely a non event - as I debated with Tooslick (Amsoil Rep.) many years ago - I asked him to show us the poor wear numbers and engine failures. Of course he couldn't!
Now about five years on and many millions of miles in millions of engines the M1 0W-40 lubricant is still the favorite with the German and other engine builders
The parallel test of M1 and Amsoil clearly showed the viscosity gain point with Amsoil as did some postings on Porsche sites - and the wear rates, if you judge such things from UOAs, were around the average mark - well Blackstone's rates at least
Amsoil got a poor reputation for a matter that to the average user was a non event!
