The first number and the letter W (winter) identify the viscosity at low temperatures. This means that an oil with the specification “5W” is more viscous than oil with the specification “0W”. The second number indicates the viscosity at high temperatures. This means that an oil with the specification “40” is less viscous than oil with the specification “50”. Multi-grade oils are identified by both viscosity specifications, e.g. SAE 0W-40, 5W-40 or 5W-50. Examples: SAE 0W-40 and 5W-40 oils have the same viscosity at high temperatures, but at low temperatures, the “5W” oil is more viscous. SAE 5W-40 and 5W-50 oils have the same viscosity at low temperatures, but at higher temperatures, the oil with viscosity class “40” is less viscous. Miscibility: All engine oils approved by Porsche can be mixed provided they are of the same Porsche oil specification. This means that it is not necessary to flush the engine when the oil is changed if another type of oil is used. However, since every brand of oil has a specially adapted unique composition, the same brand and type of oil should be used for topping up between oil change intervals if possible.
