Engine Oil: Testing and Inspection
Engine Oil Level:
> Regularly check the oil level using the on-board computer each time before refuelling.
The difference between the min. and max. marks on the segment display of the on-board computer is approx. 1.5 liters (1.6 quarts). One segment of the display corresponds to a quantity of approx. 0.25 liter (0.26 quart).
Topping up engine oil:
Warning.
Risk of burning from hot parts in engine compartment. Risk of injury by rotating parts. The engine compartment blower on the engine compartment lid can start up even with the engine off.
> Exercise extreme caution when working on the engine compartment.
Follow the instructions in the "Cautions" and "WARNINGS.".
Customer Safety Information
> Top up engine oil only with the engine off.
Engine oil is hazardous to your health and may be fatal if swallowed.
> Keep engine oil out of children's reach.
1. The on-board computer indicates how much oil must be added.
2. Switch off the engine.
Unscrew cap of the oil filler opening.
3. Add at most half a liter of engine oil at a time.
4. Measure oil level again.
Add more engine oil if necessary.
Never add more engine oil than required to reach the max. mark.
5. Close cap of the oil filler opening.
Engine Oil Recommendation:
Oil Change:
The engine oil has to be changed at the intervals listed in your Maintenance Schedule.
Service Intervals
We recommend that you have the engine oil changed at your Porsche dealer, who has the required oils and the necessary filling equipment.
If you suspect an oil leak in the engine have your dealer check it out immediately.
All current engine oils are compatible with each other, i.e. when making an oil change it is not necessary to flush the engine if you wish to use a different brand or grade of oil.
Since, however, each brand of oil has a special composition, you should, if possible, use the same oil brand if it becomes necessary to top up between oil changes.
Porsche engines have long intervals between oil changes. You can make best use of these long oil change intervals by using multigrade oils since these are largely independent of seasonal fluctuations in temperature.
If your vehicle is used frequently in stop-and-go traffic in cold weather, the engine will not always be properly warmed up.
Condensation from products of combustion may accumulate in the oil. In this case, it is advisable to change the oil more frequently so that your engine once again has 100 % efficient engine oil.
Engine oil performance class:
Engine oil is not only a lubricant, but also serves to keep the engine clean, to neutralize the dirt which penetrates into the engine through combustion and to protect the engine against corrosion.
To perform these functions, the oil is provided with additives which have been specially developed for these functions.
The efficiency of an oil is expressed, for example, by the API or ACEA classifications.
Use only engine oils with the classification API SH or SO, or ACEA A3 (Europe).
Viscosity:
Like all liquids, engine oil is viscous when cold, and thin-bodied when warm. The viscosity of an oil is expressed by its SAE class. For cold viscosity (measured at temperatures below 32°F/0°C) the SAE class is given as a number and the letter "W" (as in winter), for hot viscosity (measured at 212°F/100°C) the SAE class is given only as a number.
The viscosity of an oil is, therefore, always the same if it has the same number of an SAE class.
E.g.. A 5 W-40 oil and a 5 W-50 oil have the same viscosity when cold (below 0°C); when hot (at 212°F/100°C) the oil with the number 40 is thinner than the oil with the number 50.
Oils with two viscosities are called multigrade oils; oils with only one viscosity are termed single-grade oils.
Single-grade oils can not be used in your engine.
The viscosity of the engine oil for your Porsche has to be chosen according to the ambient temperature given in the engine oil recommendation table.
