What oil companies use only our domestic oil and not from OPEC?

We all need gas,but if we do NOT buy gas from OPEC suppliers, just maybe they will be forced to lower there price per barrel for crude. In turn the domestic oil would eventualy go down.What oil companies use only our domestic oil and not from OPEC?
There is no way to answer this question. While oil companies used to say they sourced only domestic oil, that was essentially a lie, because every oil company participates in exchanges, stores gasoline for other retailers or loads at a third party terminal. This commingling of product prevents any company from saying the fuel in your tank was sourced only domestically.





The federal government has a page which addresses this issue, here's the quote:





The Energy Information Administration (EIA) cannot definitively say where gasoline at a given station originated since EIA does not collect data on the source of the gasoline sold at retail outlets. The name on the service station sign does not tell the whole story. The fact that you purchase gasoline from a given company does not necessarily mean that the gasoline was actually produced by that particular company’s refineries. While gasoline is sold at about 167,000 retail outlets across the nation, about one-third of these stations are “unbranded” dealers that may sell gasoline of any brand. The remainder of the outlets are “branded” stations, but may not necessarily be selling gasoline produced at that company’s refineries. This is because gasoline from different refineries is often combined for shipment by pipeline, and companies owning service stations in the same area may be purchasing gasoline at the same bulk terminal. In that case, the only difference between the gasoline at station X versus the gasoline at station Y may be the small amount of additives that those companies add to the gasoline before it gets to the pump. Even if we knew at which company’s refinery the gasoline was produced, the source of the crude oil used at that refinery may vary on a day-to-day basis. Most refiners use a mix of crude oils from various domestic and foreign sources. The mix of crude oils can change based on the relative cost and availability of crude oil from different sources.

I am not sure of the companies that use only domestic fuels, and some of the previous people may be right, but in response to the last poster. You sir, are wrong. In simple economics of supply and demand, if demand for our domestic fuel goes up as compared to OPEC's ';golden'; oil, the companies tend to supply more. Maybe you haven't heard of the countries oil RESERVES. They are tapped sometimes. And while, yes, temporarily the prices for domestic will go up with the demand, when the foreign markets demand goes down, as if it's not already, considering US fuel consumption was near record lows over the last few months, the foreign market cowards just might lower their prices. I could be wrong, and I have been before, but this seems economically senseable. Oh, and around me, I have heard that Wilco/Hess is mostly if not totally domestic.
Your logic makes absolutely no sense. If we refused to buy oil from OPEC, we would lose half our supply, and prices would skyrocket.
Sunoco, BP, Conoco, and Sinclair don't directly purchase from overseas, but as noted by oiler, the exchange is always there. Citgo uses it's own oil, but is owned by the Venezulan govt, which is not friendly to us. Buying Citgo can be likened to treason. BP is a British company.
The problem is that the US cannot provide enough sweet crude oil (sulfur content less than 0.5%) for our needs and we have to import it from other countries. Most of the oil pumped in the US is sour crude (%26gt;1% sulfur content). And, the additional processing required to remove the sulfur and other impurities for refining gasoline is more costly than paying a premium for the sweet crude.
