I've worked in the industry for 25 years...in the tank farms he's talking about and also the refineries. Along the gulf coast and up the eastern seaboard he's 100% correct.
Fuel that is loaded out at refineries is also loaded into the trucks of others. Bulk storage is how it works around here. The loading racks have small tanks of the various brands additives which are mixed in as the trucks are loaded. This goes for gasoline as well.
I concur. My father has about 50 years experience with this. Ive been to the Joliet,IL Mobil refinery and watched him push the same 4 digits on a keypad to haul fuel to caseys, marathon, road ranger, phillips 66, shell, bp, etc..
People ask him all the time "where is the best place to get fuel?" He snickers and says "where it is cheapest". Ive never seen anybody give a knowing look. Most people act like they got it but you can tell they are lost. His point is to.get it cheapest because its all the same ****.
There are two exceptions locally to my area. Shell has began hauling their gas and diesel with their own trucks and that is because etna oil didnt like the buying public knowing that their gas was identical to bp. Bp has since followed suit. No bs. My lincoln ls will get 400 miles out of a tank of shell 93 octane...if I go to bp its 340 something...same octane, same amount....something is ***ky...
My 7.3 get decent mileage on FS-fastop dieselex gold brand diesel fuel. It's cheaper by 20% than anybody in the area sometimes almost a $1 per gallon cheaper. Everywhere else in.my area is hauled from the mobil refinery. It produces less mileage. 15 on fs dieselex 12-13 on everyone elses dino. :shrug: just how it goes. My sexually confused duramax gets 11ish no matter the matter lol. Towing is 9s.
