“My Truck Has Never Frozen Up…”

I use your product year round. It works great! I began using it in the winter of 1991 and am pleased with the result. My truck has never frozen up. Last year, a truly brutal winter, I passed many trucks that had fuel problems, feeling very fortunate to be moving. Since I am still relatively new to trucking, it was satisfying to know that I chose a winner in Howes Anti-Gel.
