Does ingles gas station put water in there gasoline?

never heard of water and gas mixing. usually your car would die instantly if it was trying to burn water. Looks like your not getting MPG that you want. Look at the ethanol percentage around town to get the best MPG. If I remember correctly, Less % is better and More % = burns faster. Also depends on how you maintain your car. But yeah, never heard of water and fuel mixing purposely.
