Where does the USA get most of its gasoline?

USA gets most of its gasoline from domestic refineries that refine crude oil into gasoline, not directly imported as gasoline. Most gasoline consumed in US is refined in US refineries from crude oil that comes from both domestic production and imports. US is now largest oil producer in world due to shale oil, producing about 12 to 13 million barrels per day, so most crude oil refined in US is domestically produced from Texas, New Mexico, North Dakota, and offshore Gulf. However, US still imports crude oil to meet demand and for specific refinery needs, with top sources for crude imports being Canada, which is largest source by far supplying about 60 percent of crude imports, followed by Mexico, Saudi Arabia, and Iraq. For finished gasoline imports, US imports relatively small amount of gasoline, mostly from Canada and Europe when needed. So USA gets most of its gasoline from US refineries processing mostly US produced crude plus Canadian crude. In short, most gasoline used in US is made in US from US and Canadian oil, with Canada being largest foreign source of crude oil that becomes gasoline.
