I need some info. I’ve been told by several drivers delivering fuel to store locations that ethanol is added at the rack when the tanker is loaded. Drivers have cards for each customer that tells the computer controlling the blend by percentages and additives what goes into the tank.
Given how fast gasoline goes bad due to ethanol content, I can’t see refineries making a product with a limited shelf life. Better to ship gasoline to a fill point for tankers and add ethanol immediately before shipment to a store for sale to the public.
All additives of any kind are added at the rack. Different brands and grades may have different additives, but all brands’ raw gas comes out of the same pipeline.
I had a work mate that used to be a chemist at the Anacortes refinery in Washington state. He told me that the trucks would fill up and then, based on their company brand, get the additive shot they needed. i.e. Chevron and mobile and Arco were all the same gasoline, but each got a different additive when the truck was filled.
Think of the addition of color to a base paint at the hardware store.
This was close to 20 years ago and before ethanol was common in gas.
Well,I guess I thought that ethanol was added at the delivery point. Is it or not? I know it doesn’t hold up well in storage. As far as I’m personally concerned,I think the whole ethanol industry came about as a result of government edicts & needs to be flushed permanently down the stool. Doesn’t make sense putting this crap in gasoline that costs more than the gasoline to make & then has to be subsidized by the taxpayer. Then you can add in the other problems it causes in certain types of equipment.
