13 • NEW Complete Fuel and Engine
Treatment
This unique formulation is both a fuel and engine oil additive.
When added to fuel it cleans and lubricates the entire fuel
system from tank to injectors and also removes deposits from
intake valves and combustion chambers. Protects the fuel
system against corrosion and counteracts the corrosive nature
of ethanol fuels (E5 and E10). Improves combustion efficiency
which improves power and fuel economy while lowering
emissions. When added to engine oil it improves engine
cleanliness by removing gum and varnish deposits. It also
reduces friction and wear and improves the cold temperature
fluidity of the oil. Suitable for all petrol or diesel vehicles.
