Automotive vs. RV antifreeze
Can I use regular automotive antifreeze in the black and gray water tanks and sink traps or must I use the RV antifreeze? I am in NE AR and only blow out the water lines to winterize our MH.

$12-$15 a gallon vs. $2-$4 a gallon . . . seems like a no-brainer to me.
Yeah - really don't understand the debate. I get the Wal*Mart brand for $3.47 per gallon, pre-mixed ("diluted" if you prefer). I've been using it for years in my pool because it's half the cost of stuff labeled "pool antifreeze" (which is the same thing). Good to -50F. Why mess around with automotive stuff?
