ARCO is a subsidiary of Marathon Petroleum Corporation, which is another TOP TIER licensed retailer. You can see the TOP TIER website for a full list of approved retailers.

TOP TIER gas was developed by a group of auto manufacturers who wanted to create a fuel blend that would help their cars perform at their highest potential.

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 advises that motorists would benefit from using TOP TIER gasoline whenever possible.
