This is off the original topic: If I can ask a question on the Mobil 1 20W50, Mopar Tim, is this the stuff advertised for Motorcycle V-twins? I don't see any 20W50 Mobil 1 that they list for auto use. Not sure if it makes an difference or if there are any moto-specific additives in it. It sure has a healthy zinc level at 1750 ppm.
