It’s not the amount of crude oil but the refining capacity of the US. You can be drowning in oil but if you can’t refine it what good is it? We have around 150 refineries but not all are refining oil into gasoline. There are shutdowns and then changes in additives and much much more ....
Botique fuels are killing us. Far, far too many of them.
The US does not have a refinery shortage. We refine more product that we use. We finally have excess refining capacity. We import more crude oil than we use and export the surplus product.
