exocet® fuel additive products used for maintenance are diverse, ranging for the one off rapid injector cleaning additives to fuel soluble biocides as well as tank cleaning and associated products.
‘Performance’, when attached to fuel, often conjures images of ‘faster’, ‘more powerful’ or ‘more economical’ and all of these can be achieved with the appropriate fuel additives. Fuel additives can also impact on fuel in storage, the handling properties of fuel and on the harmful effects the fuel itself can have on components within the fuel system both before and after the combustion process.


exocet® Classic should be used due to the unavailability of leaded petrol
Good for use when your valve seats require protection


In older, high speed gasoline engines, exhaust valves and the surfaces they rest on (the valve seats) operate at high temperatures and with severe mechanical stresses.

Under these high speed conditions and to a lesser extent at high load, and in the absence of special protection of the valve seat, it has been found that the material of the valve seat can be eroded away i.e. “recede” into the cylinder head. In extreme cases, this can cause lower compression, poor fuel economy, high and poor quality emissions and mechanical problems.

Compounds formed by the combustion of exocet® Classic inhibit valve seat recession by forming a thin, non-metallic layer of oxides and sulphates on the surface of the seat. This acts as a lubricant, preventing metal on metal contact and the resultant welding which causes valve seat recession.
