Benefits of Dual Fuel Conversions

Direct Benefits
  • Fuel cost savings
  • Significantly reduced emissions in dual fuel and gas modes
  • Fully rated horsepower
  • Retrofit system—expands capability and adds value to your present investment
  • Lower maintenance costs & improved engine longevity due to cleaner fuel
  • Retains diesel-only versatility
  • Fuel flexibility reduces costs when fuel prices are volatile
Indirect Benefits
  • Reduces national dependence on foreign oil
  • Environmentally responsible technology
  • Shifts major fuel cost to a more price stable fuel medium
  • Flexibility in storing fuel (i.e. diesel lasts 6-12 months in storage, natural gas lasts 20+ years)
