After more than 20 years, Seven-Eleven dropped Venezuela-owned Citgo as its gasoline supplier.
That comes as part of a previously announced plan by the convenience store operator to launch its own brand of fuel.
Seven-Eleven officials say the decision was partly motivated by politics.
Citgo Petroleum is a Houston-based subsidiary of Venezuela's state-run oil company.
Seven-Eleven is worried that anti-American comments made by Venezuelan President Hugo Chavez might prompt motorists to fill-up
Seven-Eleven -- which sells gasoline at 21-hundred of its 53-hundred US stores -- will now purchase fuel from several distributors.
A Seven-Eleven spokeswoman says the decision to sell its own brand was based on many factors, including Citgo's decision this summer to stop supplying stations in parts of Texas and other states.
A Citgo spokesman declined to comment on whether Chavez's comments had a bearing on Seven-Eleven's change in suppliers.
