Porsche Classic Motoroil 20W-50 for Porsche 356 / 914 / 911 2.0-2.7L - PCG04321090
Code: PCG04321090
Porsche Classic Motoroil 20W-50.
60L Barrel
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 especially important in this respect, since it simulates the behaviour of the oil in the crankshaft bearing during cold starts and at low temperatures.
The Porsche Classic 20W-50 is a mineral oil known as a hydrocracked base oil with mildly alloyed additives. Hydrocracked base oils are characterised by a very low level of contaminants, a very low sulphur content and very good oxidation and ageing stability, which prevents deposits, for example. At the same time, the Porsche Classic Motoroil 20W-50 has an extremely high HTHS viscosity (High Temperature, High Shear), which describes the quality of the engine oil at high temperatures (150 °C) in the lubricating gap and with high shear rate (engine speeds). Finally, the excellent shear stability ensures that the optimum lubricating properties are reliably retained at high engine temperatures, even after long periods of operation and under high loads.
In a nutshell: low levels of deposits (at both hot and cold temperatures), optimum care for classic engines and excellent compatibility with the special materials found in these engines such as cork seals or leaded bearing shells.
