Diesel 911 is a winter emergency use product. This Winter Rescue Formula reliquefies gelled fuel and de-ices frozen fuel-filters to restore the flow of diesel fuel to an engine. Diesel 911 does not prevent fuel gelling – use Diesel Fuel Supplement +Cetane Boost (in the white bottle) as a preventive measure to keep fuel from gelling. Diesel 911 and Diesel Fuel Supplement +Cetane Boost are compatible in diesel fuel and may be used at the same time.

As pressure increases to lessen America’s dependence on fossil fuels, biodiesel will become more widely used as a blended component of diesel fuel. Some states have mandated that all diesel fuels contain varying percentages of biodiesel, and the U.S. government has authorized a B20 fuel (20% biodiesel and 80% diesel fuel) for use in non-strategic […]
