Has anyone used this in their 900? I bought my usual 10w-40 Amsoil yesterday but at 14.50 a quart it is getting a bit spendy. The place I buy my oil and filter also has this Schaeffer stuff. they have a 15w-40 and 20w-50 for motorcycles. I guess I would switch from 10w-40 to 15w-40. Online it is said it's the oldest oil company in the US. I have not ever heard of it and have searched the forum and it came back with no results. Does anybody have anything good or bad to say about it? I may switch back to regular oil if it keeps going up. I think it is all just Amsoil hype causing the price to rise like it is.
