Bill I don't know....I do know that RV antifreeze is made with propylene glycol, which is touted as bio-friendly and non toxic. That's why it is used in RV's and campers, as it will not poison the potable water supply.
"Forget pounds and ounces, I'm figuring displacement!"
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.
