By treating your gasoline with Keropur additives from BASF, your customers will benefit from cleaner engines, better performance, improved drivability and lower maintenance costs. Keropur gasoline additives contain a patented active ingredient that helps prevent and remove deposits on carburetors, intake valves, fuel injectors and other engine parts.
Gasoline containing Keropur additives at the Lowest Additive Concentration (LAC) 1 meets present U.S. Environmental Protection Agency requirements for cleanliness and deposit control. Higher treat rates can clean up existing deposits and contribute to a better environment.
BASF invites you to join the growing list of leading fuel marketers that are treating their gasoline with Keropur additives. In addition to helping you identify the optimum treat rate for your fuels, we can offer joint promotional opportunities that can help you differentiate your brand.
