Surfactant

AFC Additive Component
Water that makes its way into the fuel can contribute to engine & tank corrosion as well as octane reduction and microbial contamination when phase separated from the fuel. AFC's surfactant prevents and even reverses the phase separation of water and fuel, ensuring the water is emulsified so it can later be vaporized in the engine.

Features/Benefits

Reverses phase separation of water and fuel, allowing the water to be vaporized in the engine and sent out the exhaust.
Prevents phase separation of water and fuel for up to 6 months, mitigating engine & tank corrosion, octane reduction, and microbial contamination.

Surfactant Testing

The following test was performed with two identical samples (S1 & S2) of a commercial regulated unleaded gasoline that contains 10% ethanol. Sample S1 was dosed with AFC's surfactant while S2 was not.

Figure 4
  • Figure 2: Both samples were then dosed with 0.5% by weight of red dyed water.
    • Water was dyed red to visually enhance the photos. 
  • Figure 3: Immediately after shaking, Sample S1 becomes clear - Note clarity of lines through liquid. Sample S2 becomes hazy - Lines not visible through liquid
  • Figure 4: After 5-minutes of settling, Sample S1 remains clear and homogeneous. Sample S2 separates into two layer with the lower water/ethanol layer being approximately 7% of the total sample volume. Only 0.5% water removed 70% of ethanol from a 10% ethanol-gasoline blend.
    • The upper gasoline layer became dangerously low in octane value.
    • The lower water/ethanol layer became very corrosive and low in lubricity.

  • Figure 5: Once phased separated, sample S2 was dosed with AFC's surfactant.
  • Figure 6: With agitation, sample S2 immediately becomes clear and homogeneous.
    • The parallel background lines are clear through both S1, the pre-treated sample, and S2, the post-treated sample.
  • Figure 7: After 24-hours of storage under normal conditions, there were no apparent changes to either Sample S1 or S2
