  • Corrosion inhibitor – helps prevent rust in fuel distribution systems and/or key engine parts the fuel comes into contact with, such as the gas tank and the intake valves
  • Demulsifier – helps keep water from getting disbursed with our additive in the distribution system and helps prevent accumulation of water in your gas tank by allowing it to be separated and removed
  • Solvent fluid – enables the additive ingredients to stay mixed, flow and not freeze at very cold temperatures
