You guys better start going to the refinery to get your fuel!!!
LOL....
I work for a huge pipeline company. All the fuel is the same EXCEPT the additives.
If you guys are that worried. Get a clear jug and fill it first then decided whether or not you want to put it in your truck.
You forgot you factor in the condition of the tank at the station. While the fuel being delivered is similar, the tank may have algae, water, and whatever kind of contamination.
