Explanations:
Oil Quality
The engine oil is not only a lubricant, but also fulfills many functions at the same time such as component cooling, component cleaning, and
protection from corrosion. To be able to fulfill this task, the oil contains specially-developed additives. Mineral oils are extracted directly from
crude oil. Using a series of chemical processes, these oils can be further refined (hydrocracked oils) or completely transformed (synthetic oils).
These oils provide a higher level of performance than pure mineral oils.
Only hydrocracked or synthetic oils are now approved by Porsche.
Non-seasonal Light-running Oils
Non-seasonal oils are distinguished by their low viscosity at low temperatures as well as a high level of temperature stability and a particularly low
tendency to evaporate at high temperatures due to their composition. Oils which can meet such high performance requirements can be used as
non-seasonal oils while taking into consideration the correct temperature range (see the temperature range point). These oils also have good
light-running properties because of their small low-temperature viscosity and can therefore be referred to as non-seasonal light-running oils.
Only non-seasonal light-running oils are now approved by Porsche.
Viscosity
The viscosity of an engine oil is specified by the SAE viscosity class. The first number and the letter W (winter) identify the viscosity at lower
temperatures. For example: 0W or 5W, where SW is more viscous than 0W. The second number indicates the viscosity at higher temperatures. For
example: 40 or 50, where 40 is less viscous than 50. Multi-grade oils are identified by both viscosity specifications.
For example, SAE OW4O or 5W40 or 5W50.
Examples:
0W40 and 5W40 oils have the same viscosity at higher temperatures, however, at lower temperatures, the SW oil is more viscous.
5W40 and 5W50 have the same viscosity at low temperatures, but at higher temperatures, the oil having viscosity class 40 is less viscous.
Temperature Ranges
Above -12锟斤拷 F (-25锟斤拷 C): all oils approved by Porsche for the vehicle type to be considered
Below -12锟斤拷 F. (-25锟斤拷 C:: all oils approved by Porsche for the vehicle type to be considered which have the SAE class 0W at lower temperatures.
Miscibility
The engine oils approved by Porsche can be mixed to the extent that it is not necessary to flush the engine when the oil is changed, or another type
of oil is used. This holds true for mineral oils and synthetic oils.
However, since every brand of oil has a specially adapted unique composition, the same oil should be used for any topping up that might become
necessary between oil change intervals, whenever possible.
