Ethanol 101

Remember IF your 3 hours from home and after pumping gas and about 5 miles from the station you get a intermittent miss, what may remedy the miss is………….gasoline dryer in a bottle ! Or you could just ignore the intermittent miss and drive on. My last water issue was self induced, after washing my A I believe water got into the gas tank ( no gas cap gasket) the only thing done was to add gasoline dryer and it ran with out issues.

Never buy gasoline if there’s a tanker dumping fresh gasoline, it will stir up the water setting in the station’s tanks

Along with the sediment on the bottom as well.

Even though they call them sealed system's, they are not. The tank cannot run on a negative pressure and needs to vent due to expansion and contraction of the fuel in the tank. Instead of directly venting to open air, it goes through a charcoal canister to remove fuel vapors and it's brought back into the throttle body to burn. Moisture can and does still get in the tank. Maybe not as easily as open venting, but it still get's in there.
