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.
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.
All early models up to 2.7 L G-models
