Which Air line Anti-Freeze & Fuel System Anti-Gel Additives are recommended to keep on hand in the truck? I'm running back & forth to the northern parts of New York along the Great Lakes area. I've heard about the use of alcohol (rubbing alcohol) but I don't own the truck & I'd rather not experiment. Just trying to get an idea of exactly what fuel system additive is needed, if any & for the brake line antifreeze - what to use, how much & does it just go in the brake lines itself or? Hey, no question is a dumb question when it comes to safety, right?

I carry rubbing alcohol with me, but I also make sure the airdryer is working, never've had a problem with airlines. As for fuel additive, Lucas makes it and is available in most truckstops, our terminals also have it seasonally. BOL
