Do you think that might have something to do with the fact that it's readily available on the open market for half of what they charge for the G48? Do you really believe that little bit of nitrate is going to kill your engine. Did these cars come with G-48 from new? Did it even exist back then? I know my 535i has never used it & it's still running great with no cooling system problems.
