Kind of in a bind, hopefully someone can help. Going riding early tomorrow and need some injection oil. Didn't have a chance to go today and leaving in the morning before the dealer opens and going to an area where there is no Cat dealer. Anyone have any recommendations on any other brand of injection oil to use that can be purchased somewhere besides an AC dealer? Friend of mine rides a Ski-doo and has some factory Doo oil, would it harm my machine to pour some of that in there? I have a zr600efi. Thanks for the help.
