The US imports and exports oil and oil products depending on what makes economic sense locally. This depends on transportation routes, location of refineries, oil terminals, markets, etc. other factors. The US is a very big place where conditions vary.
For instance: the US imports most of Venezuelas oil because the US has specialist refineries to process that heavy high-sulfur stuff. The refined products from that are mostly used domestically.
It does not matter when we’re paying over $4/gal here in WA and the national avg. is around #3.50 - we are not getting our oil in to our system. Remember gas prices during Trump.
