Changing oil in the old KZ to get her ready for Spring riding. Resolved to ride more this year. I have only two quarts of 10W40 Motorcycle oil. Pop into my local Carquest and all he has is some "ATV oil" for 4-strokes. Makes reference to "wet clutch protection" so I plunk down my 7 bucks and walk out with it.
My question: What is the difference between ATV oil and Motorcycle oil?
