Sunoco Gas Quality

Sunoco is a TOP TIER licensed gasoline retailer, which means that its gas meets the premier standard for gasoline performance, as set by nine major auto manufacturers — Audi, BMW, GM, Fiat Chrysler, Ford, Honda, Mercedes-Benz, Toyota, and Volkswagen. These companies set this standard because they were concerned that traditional gasoline did not allow their engines to perform as intended. The manufacturers developed TOP TIER gasoline in 2004.

TOP TIER licensed brands like Sunoco use a higher level of detergent additives that help prevent the buildup of harmful engine deposits. This enhances overall car performance. In fact, the American Automobile Association (AAA) recommends drivers use TOP TIER gas when filling up.

UltraTech Fuel Blend

In 2004, Sunoco became the exclusive fuel provider for NASCAR. The company claims on its website that its UltraTech gasoline contains the same level of detergent as the fuel it produces for NASCAR. Sunoco’s UltraTech fuel blend is available in all fuel grades at Sunoco gas stations. The company also guarantees the following for its fuels at every octane level:

Longer shelf life, due to additives like corrosion inhibitors and antioxidants
Filtered for purity
Free of methanol and MMT (a fuel additive)
