It used to be "common knowledge" that you shouldn't buy gasoline right after a station refilled their underground tanks. The common thinking was that the filling process would stir up water and suspended contaminants in the underground tank. Then, after a period of time, the contaminants would settle to the bottom of the storage tank and the pump would again deliver clean gasoline.
I think of this often when I drive to Costco to buy gasoline, only to discover that a tanker truck is at work, filling the underground storage tanks. Costco sells A LOT of gasoline, so they frequently need replenishment. And I always leave without buying.
It's clear that present-day engines with FI are equipped with extremely efficient fuel filters. And, honestly, I don't think I've recently heard anyone saying that their vehicle was harmed by dirty fuel.
So, is there any truth today to the "old wive's tale" or not?
