Porsche Classic Motoroil 20W-50

For all 356, 914 and 911 models up to the 2.7-litre G-Model

This 20W-50 Porsche Classic Motor Oil is specially adapted to the early air-cooled models for all 356, 914 and 911 models with a displacement of up to 2.7 litres.

For all 356, 914 and 911 models up to the 2.7-litre G-Model, Porsche recommends the multi-grade version with a viscosity of 20W-50. Back in the 1950s, 1960s and 1970s, engines were built with much more generous tolerances than today, which is why the viscosity of an oil must be low enough for it to penetrate into all areas of the engine as quickly and uniformly as possible during cold starts. At the same time, however, its viscosity must not be so low that a stable lubricating film is no longer present when the engine heats up.

The developers went to particular lengths to achieve excellent cold start properties for the oil so that the engine can be lubricated as quickly as possible when started. The CCS test was crucial in this respect since it simulated the behaviour of the oil in the crankshaft bearing during cold starts and at low temperatures.
