TBF I have always considered citgo gas to be contaminated.
and that is not even a lame attempt at blue stars. i find their gas always subpar and dirty when i am forced to use it.
Citgo doesn't own any fuel outlets, all distributors. They own a lot of terminals that fed these gasoline/diesel outlets.
A terminal receives gasoline in raw form, called RBOB or KBOB. One is regular and the other is premium gasoline.
The gasoline is fungible, meaning interchangeable with other gasolines on say the Colonial pipeline.
Once it gets to the Citgo terminal, it is blended with the brand's special detergents.
Now here is the kicker, Exxon or shell or whoever can call the Citgo terminal and ask them to blend up a batch of their stuff cause they are out. Citgo has all their recipes and can blend one up for them. Always trading with each other so the difference in your study must be the detergent recipe Citgo uses.
