Hi All-
Hope this isn’t considered a silly question, but I’ll throw it out here anyway..
I am seriously considering a purchase of an ‘02 R1150RT ex-police model with approx 80k on the clock. Engine sounds decent and everything works at it should. Current owner states that both he and the previous owner used Chevron Supreme ASI SP 20w50 motor oil. Online info seems limited, but best I can tell is that the ZDDP for that oil appears to be 880, unless I misunderstood the conversion from percentages. My concern is that the bike may not have been using oil with enough zinc, at least since it was no longer used by law enforcement. I’ve always understood the minimum number for zinc should be 1200 for these types of engines.
Not trying to make this an oil thread by any means, but I am not familiar with Chevron Supreme as an oil for motorcycles, and concerned about engine wear since the bike does have 80k on it already. I’d appreciate feedback from members whether to be concerned or not.
