Also there was some stations that claim no ethanol in their storage tanks, yet tested for more the. The 10%, and some that had around 5%.. So a good way to see if your deal of choice actually has ethanol in it is sending it off

I can assure you there is no coating coming off of the piston in the pump, What plating IS on the pump is DLC which really just doesn't come off, especially not with fuel that you can pour into a plastic gas tank.
