Just put in some fresh Mobil 1
I've always been a big believer in Mobil Oil. My theory is the more money an oil company has the more technology they put into their product. But then again for my 750 BF, I'll probably use the Kawasaki brand oil.self using 10w/40
have used shell and mobil
find that when using shell, there was oil usage, and much less when using mobil, not sure if that is good or bad!!
