MULTIPLE
ACTION CONCENTRATED ADDITIVE / COMPLEMENT
Combustion improvers and
fuel stabilizers.
It decants the
microdroplets of water in suspension that the fuel contains.
Bactericide and fungicide, eliminates algae and fungi. (Bulletin 15)
It keeps the
fuel tank and circuit clean of rust and corrosion.
Stabilizer that slows fuel degradation.
Detergent, cleans pumps and injectors, improves combustion.
Injection system lubricant,
for Low Sulfur Diesel, ASTM D-6079 (HFRR) / ISO 12156 standards.
Corrosion inhibitor in
high and low temperature areas of the engine.
EFFECTS " Combustion
Optimization = Ecology and savings"
Optimizes the
performance of the fuel injection system.
Reduces the
emission of soot and black smoke by 80%. (Bulletin 29)
Extends the
life of the Diesel Particulate Filter (DFP).
Neutralizes corrosion
in exhaust
valves and turbochargers (Technical Document RB-8)
Reduces maintenance
costs and extends engine life. (Technical document RB-13)
Saves fuel
(Bulletin 4)
