Diesel 911 More Info

Gelled Fuel / Icing

If your vehicle will not gain power in cold weather then you are experiencing a diesel cold-weather emergency. The best diesel fuel emergency product on the market is Diesel 911 to reliquefy gelled diesel fuel and de-ice frozen fuel-filters. No other product is as fast or as effective to get you back on the road safely.

There’s a reason drivers call it the GOAT (Greatest of All Time). It is the original emergency use product and has been trusted by generations of drivers for decades. Imitators have come and gone over the years, but nothing compares to the original Diesel 911.

Once your diesel is flowing again, it is important to treat it with Diesel Fuel Supplement +Cetane Boost to prevent future gelling. Diesel 911 is not an antigel; it will not prevent gelling. Please note that Diesel 911 and Diesel Fuel Supplement are completely compatible and can be used at the same time.
