I needed to go get some basics for my bike today, premix oil and some grease. So I got a tub of Bel-Ray Waterproof, I've read good stuff about being able to use it for everything, linkage, air filter, everything. When I was going through oils, I remember a few guys at the shop when I got my bike recommending Silkolene. So I read the label and it sounded good and I picked it up. Only one thing confused me, it says a synthetic/ester blend. The Maxima Super M I was using said synthetic petroleum. I checked my Service Manual and all it says is not to run vegatable or mineral oils. I've heard this stuff has a more distinct smell too, but odors are no concern of mine. As long as it protects well and doesn't cause any problems. But I'd appreciate if you could share your own experiences or problems with Comp-2.
