Here's what I don't understand about this comment. Redline uses the best oil base stock known to man currently and typically uses a higher percentage of additives than anyone else. It's a win win in my book. I have years and years of practical experience with Redline oils and can't b happier on the reliability and longevity. I'm not saying that other oils won't give good results. I just like to go with a proven top quality oil. Why take a chance?
Both M1 motorcycle oils and the Amsoil products I named are in fact proven, both in the lab (by a competitor, in Mobil's case), and in practical application, to my complete satisfaction. The top 50% of Maxima
's line has done well, too. The statement regarding Red Line's base stock is arguable.
I have apart right now an '06 YZ450 with God knows how many hours on it (I know the bike, a conservative guess would be 500) that blew a head gasket and was run dry for so long that it literally started to melt the combustion chamber dome between the exhaust
seats. Both seats were so badly distorted by heat that they had to be cut too deep and had to be replaced. The top ring groove of the piston collapsed on the ring, pinching it in place, but the skirt did not seize. Not one single lubricated part of the engine suffered ANY damage on any bearing surface. None.
What chance am I taking, exactly?
