Ok...per the experts on the subject....(not me)
"The following gas companies import Middle Eastern oil."
Middle East (barrels) EIA, Persian Gulf 2010 (barrels per year)
Shell 205,742,000 5,620,000*
Chevron/Texaco 144,332,000 91,168,000
Exxon /Mobil 130,082,000 121,300,000
Marathon/Speedway 117,740,000 76,660,000
Amoco 62,231,000 55,906,000 (merged with BP in 1998)*
"Here are some large companies that do not import Middle Eastern oil"
Sunoco no middle east or Persian gulf oil
Conoco no middle east but 18,687,000 persian gulf
Sinclair non of either
BP/Phillips 0 middle east 55,906,000* Persian gulf
Hess Neither
Valero 0 middle east 92,305,000 Persian gulf
Murphy Oil USA non of either...
Biggest thing you have to remember is that a number of companys mix USA oils and middle east and or Persian Gulf oils..... believe it or not, WalMart actually sells fuel like Murphy's...Non Middle east oils....no Persian Gulf oil
All in all, unless you buy sunoco, Sinclair Hess or Murphy's...you will be using USA and Persian mixes.....so sayeth the experts.....LOL
