I see a lot of people on here reccomend Diesel oils like mobil and Rotella for motorcycles in the engine and transmissions, but most on here are also riding harley's. How would this oil stand up in high performance bikes. I have a 2007 Honda CRF450r and 2007 Suzuki GSXR600 and wouldnt mind saving some money on oil vs. "motorcycle oils." What are the benifits/drawbacks of using a heavy duty diesel oul in a motorcycle? Or maybe i should phrase it this way, what are the benifits of using a motorcycle specific oil? Would a HD Diesel oil stand up to the racing enviroment for my honda CRF450r? thanks guys!!
