Is ARCO Gas Bad for Your Car? Is ARCO Gas Good?
ARCO is a TOP TIER licensed retail brand in the U.S, Mexico, and Canada. That means all ARCO gasoline grades must be treated with an approved TOP TIER additive that has been proven to benefit car engines. In short, since ARCO gas is TOP TIER Detergent Gas, it is among the best quality gas available.
An independent study conducted by the American Automobile Association (AAA) found that vehicles using TOP TIER gas had “19 times fewer carbon deposits on injectors, intake valves, and in the combustion chamber when compared to regular gasoline.” The study also found TOP TIER gas has a “cleansing effect.” AAA’s advice: “Motorists would benefit from using TOP TIER gasoline as their primary fuel.”
TOP TIER believes all TOP TIER licensed brands are equal. That means, ARCO gas is comparable to 76, Kroger gas supplied by Shell, Sunoco, and Valero (all previously reported as TOP TIER Detergent Gasoline retailers).
This information was verified by a review of ARCO’s Northwest regional site, its Southwest regional site, and the TOP TIER website.
