The Top Tier Gasoline standard, which requires a higher-percentage of detergent additive than the EPA minimum criteria, was developed with the assistance of BMW, General Motors, Honda, Toyota, Volkswagen, and Audi. They contend that lesser detergent additive concentrations may cause greater deposits to form on engine parts like the intake valves and fuel injectors.
