GasMastor Advantages

Reduced Emissions
  • Significant reductions in CO2, NOx and particulates.
Reduced Fuel Costs
  • Substituting more expensive diesel with a cheaper gas delivers significant $$$ savings.
Increased Engine Efficiency
  • Using a flammable gas to encourage complete combustion greatly increases the efficiency of the engine.
Extended Engine Life
  • Soot is the abrasive by-product of combustion. Lower soot build up extends engine life.
Lower Maintenance Costs
  • Engine oil analysis allows an extension of maintenance intervals and lowers life-of-engine maintenance costs.
Increased Fuel Capacity
  • The additional gas supply effectively extends the range/running time of the engine.
