Instructions for 911 and Turbo oil level through 1998
We recommend setting the oil level for the 911 & Turbo slightly differently than described in the owner’s manual. From our experience, the procedure described below is best for all operating conditions and will minimize oil leakage due to overfilling.
The oil level checking procedure:
- The car must be on level ground.
- The engine must be running at idle speed.
- The engine oil must be up to full operating temperature and the external oil cooler(s) must be hot to verify that the thermostat is open (lightly touch front cooler(s) to feel for heat).
- The level is now viewed on the dipstick, (located in the rear of the engine compartment-inside the oil tank on cars through ’89). The oil level must not be higher than half way between and minimum and maximum mark. Preferably the oil level should be between 1/3 and 2/3s on the dipstick.
With the oil level at the prescribed level, the oil level gauge located on the instrument panel should approximate the level on the dipstick. Do not be concerned if the gauge is not exact.
While driving the car the oil level gauge will almost be in the ‘red sector’. This is no reason for concern; this is normal. The oil level gauge will also read in the 'red sector' when the temperature is less than 180 degrees F. Again this is no reason to be alarmed.
When stopping for a traffic light, on level ground, with the oil at operating temperature, the level gauge should give an approximate reading of the actual oil level in the oil tank.
Please follow these instructions and your Porsche 911 or Turbo will not have oil leaks due to overfilling the oil level.
Preparing your car for winter storage
- Have gas tank near full. (minimizes condensation)
- Try to have car warmed up completely. (burns out condensaton)
- Inflate tire to maximum (around 50 psi). (helps prevents flat spotting)
- Set heater to maximum. (stops mice from getting in)
- Disconnect battery. (still should be trickle charge)
- Leave doors and hood partially latched. (rejuvenates seals)
- Turn engine over every 6-8 weeks. (stops engine from seizing & tires
from flat spotting)
a. Remove key from ignition
b. Put car in 4th gear
c. From behind with the engine compartment open, bump forward or pull
baclwards on car until fan rotates 1/2 turn.
