Up to the 1980’s lead was usually added to gasoline as an additive. Lead played a definite role in the proper functioning of an internal combustion engine.

On the one hand, lead was used to protect engines by reducing combustion chamber temperatures, as well as reducing the temperature of valve seats. Those two engine components are subject to constant friction and elevated temperatures.

On the other hand, lead also helped lubricate cylinder walls and valve seats, by limiting the premature wear of these engine parts, which are subject to friction and overheating.

Anti-pollution legislation has forbidden the addition of lead to gasoline for environmental reasons. However, the lack of lead in auto-fuel has also caused an increase in the operating temperature of older Porsche engines prior to the 3.2 Liter motor equipped with a catalytic converter. This is also applicable to the older type engines which have not been fitted with newer valve seats or cylinder walls better suited to hotter operating temperatures.

With the objective of helping you better safeguard your original Porsche engine, Jean Buser brings you the new « Valve Expert » lead substitute by Motul. Its unique phosphorus-based formulation gives you the same benefits as lead, but enables you to comply with current anti-pollution legislation. Your engine’s cylinder walls and valve seats will be adequately lubricated and protected by this additive.

« Valve Expert » is recommended for all Porsche engines, from 1965 to the non-catalyzed 911 3.2 L Carrera motor. A measuring spout allows you to quickly and precisely meter out the amount you need for your gas tank when you fill up. « Valve Expert » is completely diluted in your tank’s gasoline, and will not form any deposits at the bottom of your fuel tank, even if the latter is not driven under an extended time period.
