Ignite Racing Fuel’s Ethanol has been approved for NTPA competition.

Even though NTPA has stated ethanol as a legal fuel in the rulebook for several years, we have never had a efficient way to test and/or approve any ethanol for use in competition in NTPA. Several months ago Ignite Racing Fuels submitted a request to become an approved ethanol fuel of the National Tractor Pullers Association. They also provided the equipment to test Ethanol and confirm the content of the fuel.

Ignite Racing Fuel’s “Green 108” and “Red 114” has been approved for NTPA use.
