Are you buying gasoline from the Middle East? The Saudis are boycotting American goods right now so perhaps we should return the favor.
Every time you fill up the car, you can avoid putting more money into the coffers of Saudi Arabia. Just buy from gas companies that don’t import their oil from the Saudis.
Major companies that DO import Middle Eastern oil:
Shell, Chevron/Texaco, Exxon / Mobil, Marathon / Speedway, Amoco
Major companies that DO NOT import Middle Eastern oil:
Citgo, Sunoco, Conoco, Sinclair, BP/Phillips, Hess
