Are you talking about Bardahl Oil. I would tell wrench it's my bike!! Here's the Amsoil and the filter. Then I would watch him, if possible to make sure he put it in.
Read the Motorcycle Oil White page on that link.Red02FXST said:I don't like beating a dead horse on the issue of oils!!!
JMHO but Amsoil is the BEST. And your using it.
