TOP TIER Detergent Gasoline standards were developed by six automotive companies: Audi, BMW, General Motors, Honda, Toyota and Volkswagen.
Why was TOP TIER Detergent Gasoline developed?
TOP TIER Detergent Gasoline was developed to increase the level of detergent additive in gasoline. The EPA requires that all gasoline sold in the U.S.
contain a detergent additive. However, the requirement is minimal and in many cases, is not sufficient to keep engines clean. In order to meet TOP TIER
Detergent Gasoline standards, a higher level of detergent is needed than what is required by the EPA. Also, TOP TIER was developed to give fuel
marketers the opportunity to differentiate their product.
Why did the six automotive companies join together to develop TOP TIER?
All six corporations recognized the benefits to both the vehicle and the consumer. Also joining together emphasized that low detergency is an issue of
concern to several automotive companies.
What are the benefits of TOP TIER Detergent Gasoline?
TOP TIER Detergent Gasoline will help keep engines cleaner than gasoline containing the "Lowest Additive Concentration" set by the EPA. Clean
engines help provide optimal fuel economy and performance and reduced emissions. Also use of TOP TIER Detergent Gasoline will help reduce deposit
related concerns.
