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.

Where I live, you are not allowed to dump any automotive antifreeze in storm drains or down your sink drain. Big fine if they catch you. As mentioned, not all treatment plants are capable of treating antifreeze. If in doubt, call your sewage treatment company and ask.
