"They use foreign gas to ship foreign gas."
I had to check - per CIA World Fact book - approx. 9.6 million bbl/day from US; 10.3 million bbl/day imported; 1.9 million bbl/day exported from US; 19.15 million bbl/day consumed in the US.
"The discrepancy between the amount of oil produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes, refinery gains, and other complicating factors."

About half of the consumption comes from US sources so not bad. Consumption would not be only fuel but petroleum based products (plastics, sythetic fibers for furniture coverings, carpets, vinyl flooring, clothes, etc).
