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 liters. This mineral oil is available in 1 or 5-liter cans.
For all 356, 914 and 911 models up to the 2.7-liter 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 behavior 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 characterized by a very low level of contaminants, a very low sulphur content and very good oxidation and aging stability, which prevents deposits, for example. At the same time, the Porsche Classic Motor Oil 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.
