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. When Deposits Build Up, You Slow Down. Deposits can build up on fuel injectors and intake valves – robbing your engine of performance.
