TOP TIER Detergent Gasoline is a new class of gasoline with enhanced detergency andno metallic additives. It meets new, voluntary deposit control standards developedby six automotive companies that exceed the detergent recommendations of Canadianstandards and does not contain metallic additives, which can damage vehicle emissioncontrol components.
Where Can TOP TIER Detergent Gasoline Be Purchased-
The TOP TIER program began in the U.S. and Canada on May 3, 2004. Some fuel marketershave already joined and introduced TOP TIER Detergent Gasoline. This is a voluntaryprogram and not all fuel marketers will offer this product. Once fuel marketers makepublic announcements, they will appear on a list of brands that meet the TOP TIERstandards.
Who developed TOP TIER Detergent Gasoline standards-
TOP TIER Detergent Gasoline standards were developed by six automotive companies:BMW, General Motors, Honda, Toyota, Volkswagen and Audi.
Why was TOP TIER Detergent Gasoline developed-
TOP TIER Detergent Gasoline was developed to increase the level of detergent additivein gasoline. In the U.S., government regulations require that all gasoline sold inthe U.S. contain a detergent additive. However, the requirement is minimal and inmany cases, is not sufficient to keep engines clean. In Canada, gasoline standardsrecommend adherence to U.S. detergency requirements but do not require it. In fact,many brands of gasolinein Canada do not contain any detergent additive. In order to meet TOP TIER DetergentGasoline standards, a higher level of detergent is needed than what is required orrecommended, and no metallic additives are allowed. Also, TOP TIER was developed togive 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 and the intentional additionof metallic additives 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 containingthe “Lowest Additive Concentration” recommended by Canadian standards. Clean engineshelp provide optimal fuel economy and engine performance, and also provide reducedemissions. Also, the use of TOP TIER Detergent Gasoline will help reduce deposit relatedconcerns.
Who should use TOP TIER Detergent Gasoline-
All vehicles will benefit from using TOP TIER Detergent Gasoline over gasoline containingthe “Lowest Additive Concentration” recommended by Canadian standards. Those vehiclesthat have experienced deposit related concerns may especially benefit from use ofTOP TIER Detergent Gasoline.
