Anyone have an opinion on this? Preferably one based in solid experience rather then just using it and thinking it's great w/o reason. Because lets face it, a lot of people do that. I was using M1 V-twin before but it's a model that inherently has some piston slap and i thought this might help tame that a bit, but i have no idea whether this is a known good oil or some budget junk. Never heard of it till someone told me they use it and suggested its a good quality oil.
