ENGINE OIL:
Engine Oil Consumption:
It is normal for your engine to consume oil.
The rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well as the amount of dilution and oxidation of the lubricant.
If the vehicle is used for repeated short trips, and consumes a normal amount of oil, the dipstick may not show any drop in the oil level at all, even after 600 miles (1000 km) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed.
The diluting ingredients evaporate out when the vehicle is driven at high speeds, as on an expressway, making it then appears that oil is excessively consumed after driving at high speeds.
If the conditions you drive your vehicle in are dusty, humid, or hot, the frequency of the oil change intervals should be greater.
If the vehicle is driven at a high rate of speed, climatic conditions are warm, and the load is high, the oil should be checked more frequently, as driving conditions will determine the rate of oil consumption.
- The engine in your vehicle depends on oil to lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked regularly and kept at the required level.
- Make it a habit to have the engine oil level checked with every fuel filling.
- The oil pressure warning light is not an oil level indicator.
The oil pressure warning light indicates serious engine damage may be occuring when lit, if engine rpm is above idle speed.
Engine Oil Level:
WARNING! Engine oil is hazardous to your health and may be fatal if swallowed.
The oil level should be regularly checked on the oil level gauge in the instrument panel.
The dipstick and oil filler are in the rear luggage compartment.
Preconditions for correct oil level measurement with the dipstick:
- Vehicle is level,
- Engine is switched off and at operating temperature.
- Let engine oil flow into the oil pan for a few minutes after the engine has stopped running.
CAUTION: Take care while checking and topping up engine oil not to soil the luggage compartment or items of luggage.
Checking The Oil Level:
1. Withdraw dipstick and wipe it with a clean, lint-free cloth.
2. Push dipstick fully home, withdraw again and read off the oil level. Push dipstick in as far as the stop.
The oil level must in no case fall below the minimum or exceed the maximum oil level on the dipstick.
The difference between the two marks is approximately 1.5 liters/1.6 quarts .
Topping Up Engine Oil:
1. If necessary, add engine oil half a liter at a time. Unscrew the cap of the oil filler.
2. Check oil level with the dipstick again after a few minutes.
3. Push dipstick in as far as the stop. Push filling aid in with the cap and close cap carefully.
Oil Change:
The engine oil has to be changed at the intervals listed in your Maintenance Schedule.
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.
