Some customers who pumped contaminated unleaded gas from the Fastop on Airport Road reported on social media they found water in their tanks. While some pointed to heavy rains on the night of July 16, others speculated that water had been poured into the tanks intentionally.
That's not the case, according to Motor Fuels Section program manager Marcus Helfrich. A state inspector tested the contents of each tank on July 17, and the only issues were accidental pipe-crossing and basic chemistry, Helfrich said
The water that customers found in their tanks is the result of a chemical interaction between the ethanol in regular unleaded fuel and the water in diesel tanks, Helfrich said.
