Has anyone used this oil in their bike? says on the bottle it has a SG Api rating. Found a bunch for $2.99 a qt, don't know if its worth trying.I looked thru 42 pages of uoas and couldn't find any mention of it.,,
SG is some pretty old stuff-plenty of zinc probably, but high noack (volatility), and not an oil I would leave in there long. And I would only buy if fifty cents per qt. You can get a modern, cleaner running 20W-50 oil for that price.
It would be fine for a motorcycle. They mash the oil up in no time and you dont run it for a long time between changes. I used 20w50 in my KLR650. It was ok. I prefer the diesel truck oil 15w40 though.
