Fully synthetic special lubricant to be used for valve shafts of sidevalve/flathead engines.
How It Works
In simple or older four-stroke engines, the valves are arranged sidelong upward (SV engines / flathead). The valves are not located in the cylinder head and are not connected to the lubricating system of the motor. For this reason, another kind of lubrication is necessary.
To be used in engines with air valve and inlet over exhaust engines where frequently one or several valves are not lubricated.
The fully synthetic basic components guarantee a complete combustion without leaving any deposits or coking in the combustion chamber.
The Upper Cylinder Oil, that reaches the shaft only in very small quantities, must be of outstanding lubricating properties.
On the other hand, it should - once arrived in the combustion chamber - completely burn off, without leaving deposits or coking. And it must generate enough oil mist to ensure the lubrication of the exhaust valve.
The latter feature has the pleasant side effect that exhaust systems of four-stroke engines, which are regularly operated with Upper Cylinder Oil, are far more durable than comparable vehicles that have to do without this fuel additive.
When adding Upper Cylinder Oil to the fuel, not only the valves are lubricated, but also pistons, cylinder bores and injection nozzles of all four-stroke engines.
The wear on pistons, cylinder liners, valves and injectors is significantly reduced. And even rough and hard-running engines often find their way back to the soft sound of the new car.
