That's exactly it. The sloshing around in the truck mixes it up. And it doesn't matter which order it goes in either. Sometimes if the Ethanol rack is empty an noone filling a tanker, he'd get his Ethanol first then go to the gas rack. I learned alot about gas with him working there. Like most fuel all comes off the same rack, same pipeline no matter what station it's going to. It's the additives that get put in it that make the difference. Like Shell has lots of additives and detergents added, but it's the same damn fuel you buy at 7-11. Conoco/Phillips66 is one that has their own rack and pipeline, but sometimes they even sell to others. Murphy's stations outside the Walmarts, same gas that is at 7-11 and most of the mom and pops but it's in the Murphy's contract it must be carried in a tanker lettered for Murphy's. He hated hauling Murphy's cuz he'd have to go park his unmarked tanker and go pick up an empty Murphy's tanker just to take a load to Walmart. And sometimes, he could load up 8000 gallons, and drop 3000 gallons here, 2000, here, 2000 here and 1000 here so make 2-4 stops with the same load on the same side of town, but if he had a Murphy's load then he might only a pull a 3000 or 4000 gallon load and then go back and drop that tanker and pick up his unmarked. Or, have 8000 gallons on and make 3 drops at 3 different Murphy's that much further apart on opposite sides of town or even in different cities.
