What gas stations sell American gas (which includes imports from Canada and Mexico as they are part of North America)?

Here are some companies that do not import Middle Eastern oil:

Sunoco......................... 0 barrels
Conoco........................ 0 barrels
Sinclair....................... 0 barrels
BP / Phillips................ 0 barrels
Hess. ............................. 0 barrels
ARC0............................. 0 barrels
Maverick......................... 0 barrels
Flying J. .......................... 0 barrels
Valero............................ 0 barrels
Murphy Oil USA * ............. 0 Sold at Wal-Mart , gas is from South Arkansas and fully USA owned and produced.

Are you aware that the Saudis are boycotting American products? In addition, they are gouging us on oil prices.

Shouldn't we return the favor? Can't we take control of our own destiny and let these giant oil importers know who REALLY generates their profits, their livings? How about leaving American Dollars in America and reduce the import/export deficit?

An appealing remedy might be to boycott their GAS. Every time you fill up your car you can avoid putting more money into the coffers of Saudi Arabia . Just purchase gas from companies that don't import their oil from the Saudis.

Nothing is more frustrating than the feeling that every time I fill up my tank, I'm sending my money to people who I get the impression want me, my family and my friends dead.

 

The following gas companies import

 

Middle Eastern oil:

Shell.................................... 205,742,000 barrels
Chevron/Texaco.................... 144,332,000 barrels
Exxon /Mobil........................ 130,082,000 barrels
Marathon/Speedway............. 117,740,000 barrels
Amoco.................................. 62,231,000 barrels

CITGO oil is imported from Venezuela from Dictator Hugo Chavez who hates America and openly avows our economic destruction! (We pay Chavez's regime nearly $10 Billion per year in oil revenues!) Note: CITGO Oil Company  is owned by the country of Venezuela

The U.S. currently imports 5,517,000 barrels of crude oil per day from OPEC. If you do the math at $100 per barrel, that's over $550 million PER DAY ($200 BILLION per year!) handed over to OPEC, many of whose members are our confirmed enemies!!!!! It won't stop here - oil prices could go to $200 a barrel or higher if we keep buying their product.

All of this information is available from the U.S. Department of Energy and each company is required to state where they get their oil and how much they are importing.

But to have a real impact, we need to reach literally millions of gas buyers. With the help of the internet, it's really simple to do. Now, don't wimp out at this point....keep reading and I'll explain how simple it is to reach millions of people!!

Send this note to everyone you know, and tell them to send it.

We need to do something, NOW !!! Buy American, and don't drive as much. We'll save lots of gas, and money.
