Overview Of Approved Engine Oils
Note:
This Technical Information replaces the following TI: All No. 2/06 dated July 28, 2006.
Vehicle Type:
All Porsche standard production vehicles with the exception of the Porsche Cayenne (V6). The engine oils for the Porsche Cayenne (V6) are listed in a separate bulletin.
Model Year:
As of 1984
Concerns:
Overview of engine oils approved by Porsche, "Porsche approval list".
Information:
Approved Oil Availability
Porsche approved oil availability varies by global region. Some oils on the following "Approved List" may not be available in certain regions of the North American market, or, may only be available in overseas markets exclusively.
When searching the "Approved List" for a particular manufacturer or brand name, keep in mind that the below listed "Sales Region Codes" are marketed for the North American region:
CDN - Canada
USA- United States of America
WW - World-Wide
Oil Quality:
Note:
Use only oils approved by Porsche listed in this bulletin, all previously issued bulletins are no longer valid. Remaining inventory of engine oil as specified in the previously valid TI "Group 1, No. 2/06, dated July 28, 2006" can be used up to June 30, 2007. Please observe the "Valid until DD/MM/YY" column in the oil approval table provided below.
The engine oil is not only a lubricant, but also fulfils many functions at the same time such as component cooling, component cleaning, and protection from corrosion. To be able to fulfil these tasks, 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 that meet such high performance requirements can be used as non-seasonal oils while taking into consideration the correct temperature range (see the "Temperature ranges" point). These oils also have good light-running properties because of their low viscosity at low temperatures 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 5W is more viscous than 0W.
The second number indicates the viscosity at high temperatures. For example: 40 or 50, where 40 is less viscous than 50 at the same temperature.
Multi-grade oils are identified by both viscosity specifications. For example: SAE 0W-40 or 5W-40 or 5W-50.
Examples:
0W-40 and 5W-40 oils have the same viscosity at high temperatures. However, at low temperatures, the 5W oil is more viscous.
5W-40 and 5W-SO have the same viscosity at low temperatures, but at higher temperatures, the oil with viscosity class 40 is less viscous.
Temperature Ranges
Miscibility:
The engine oils approved by Porsche can be mixed with each other. 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 oil should be used for topping up between oil change intervals if possible.
Overview:
Note:
We have reached an agreement with the mineral oil companies which involves setting a time limit on the validity of our engine oil approvals.
The period of validity is between 2 and 3 years. The expiration date of the approval is given in the last column in the list shown.
Once this validity period has elapsed, the approval in question is revoked unless an extension is requested by the relevant manufacturer.
