Quality Fuel

More Quality in Every Drop

Conoco® gas has 3 times more detergent additive than the minimum required by the EPA and 30%* more than the TOP TIER® Detergent Gasoline standard recommended by major car manufacturers.** Learn how Quality Fuel can undo the side effects of inferior gas.

*Based on average proprietary additive treat rate. BMW, General Motors, Honda, Toyota, Volkswagen, Mercedes-Benz, and Audi sponsor the TOP TIER® Detergent Gasoline standard. TOP TIER® is a registered trademark of General Motors.


**Due to a nationwide supply shortage, some stations in CO, IA, NE, GA, MO, and OK will have reduced treat rates of gasoline detergent additive. Gasoline sold at these stations still meets all governmental specifications, but may not meet TOP TIER™ standards or our normal additive rates for Conoco® fuel. This shortage is estimated to last through March 2022.
