I'd even be willing to bet the BMW M3 engines would show excellent results using Redline 5w40 compared to that 10w60 oil they call for now.

I've got a boatload of Schaeffer's that I won't use on my in-warrany BMWs because its not "full syn" or BMW LongLife approved. However, I think the Schaeffer's would do as well as the "factory" BMW syn. I really like BMWs, but repairs can kill you. BTW, my old 86 BMW was sold at 197k and had little if any consumption with xW30 it whole life. Jack
Originally posted by Patman: The M3 engine failures were later traced to bad bearings, not the oil, although 5w30 is probably still too thin for them. But Redline 5w40 is a middle 40wt oil, with an excellent HTHS and this oil does not shear back easily either. I'd be willing to bet the 10w60 oil does. So in the long run, you'd be better off with Redline in the M3.

So much for gods heaviest oil this side of wheel bearing grease being the solution for all problems...
