I definitely would not. Might take a while, but eventually it can blow your engine. 30 weight oil is too thin, that’s why the book calls for 40 or 50 weight. The “W” number isn’t important unless you’re riding in the wintertime.

Bottom line is, the risk isn’t worth it. Save the -30 weight stuff for your car next time it needs an oil change and get some -40 or -50 for the bike.
