Description
Keropur® 3448 N is a high-performance multipurpose additive concentrate for gasoline, formulated around BASF's proprietary polyisobutene amine (PIB-monoamine) detergent technology combined with a thermally stable special polyether and an effective corrosion inhibitor. When blended with a suitable mineral oil carrier, it forms a complete multipurpose gasoline additive package with proven deposit control and corrosion protection performance.
The detergent system efficiently controls and removes deposits throughout the vehicle intake system, including the intake manifold, intake valves, fuel injection nozzles, and carburettors, contributing to improved engine efficiency, reduced emissions, and extended component life. The integrated corrosion inhibitor provides reliable protection for tanks, fuel lines, and carburettors against corrosive attack.
