Gas line anti-freeze

The simple answer is a flat-out “No!” Modern cars using modern gasolines simply don’t freeze their fuel lines.

Occasionally you run into someone who insists it happened to his neighbor’s uncle’s work buddy. Ask how he knew it was a frozen fuel line rather than some other cold-weather problem.

Save the Heet or Dri-Gas or related product for known water problems, such as when you go through the car wash with the fuel cap off and the filler door wide open. (I’m not making this up. This forum gets this problem maybe one a month.) Don’t waste your money on using it for regular winter treatment.
