That little bit of oil in the gas hasn't produced any smoke and it seems to run fine.


2 cycle mix won't hurt a 4 stroke, and it will add lubrication to the cylinder walls and piston rings, but it won't do a thing for the main and rod bearing surfaces. They need lubrication also.

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
