Additives

• Hybrid compound blends
  • Combustion catalyst (organo-metallic compound which lowers the ignition point of fuel in the combustion chamber reducing the temperature burn from 1200 degrees to 800 degree F)
  • Burn rate modifier (increases the fuel burn time result in an approx. 30% increase of the available BTUs from the fuel)

  • Solvent Yellow 124
  • Solvent Blue 35

• Others
  • Nitromethane (increases engine power, "nitro")
  • Acetone (vaporization additive, mainly used with methanol racing fuel to improve vaporisation at start up)
  • Butyl rubber (as polyisobutylene succinimide, detergent to prevent fouling of diesel fuel injectors)
  • Ferox (catalyst additive that increases fuel economy, cleans engine, lowers emission of pollutants, prolongs engine life)
  • Ferrous picrate (improves combustion, increases mileage)
  • Silicones (anti-foaming agents for diesel, damage oxygen sensors in gasoline engines)
