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 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.
