Fluid Topping Up
Engine oil
It is normal for your engine to consume oil and the rate of consumption will vary with many factors. The oil consumption may be higher when the vehicle is new or if you frequently drive at high engine speeds.
It is important to follow the service schedule for oil and filter changes and to regularly check the level of your oil in between.
You will only be able to estimate the oil consumption after the vehicle has been driven for several thousand miles or kilometres.
NOTE: Lubricant additives could damage the engine or gearbox. Damage caused by such additives is not covered by the vehicle warranty. Further information is available from your McLaren retailer.
NOTE: The oil pressure warning light is not a low oil level indicator.
Checking the engine oil
- Ensure the following conditions are met:
- Vehicle stationary and positioned on a level surface.
- Neutral selected and the foot brake applied (use left foot).
NOTE: The foot brake must be applied for the entire duration of the oil level check.
- The level is viewed in the Vehicle Info section on the Driver Display.
Start the engine and hold the engine speed at 2,000 rpm for 120 seconds. Allow the engine oil temperature to reach a temperature of 90°C (194°F).
NOTE: The throttle pedal can be fully depressed as the engine speed will be electronically limited to 2,000 rpm. - When the timer has reached ‘0’, the oil level will be shown on the Driver Display along with a description.
NOTE: The line on the display indicates the maximum oil level for 19 seconds after the oil level is read.
- If the engine oil is below the target level, stop the engine and top up the oil following the following procedure.
NOTE: Once the oil level check has been completed and returned a value, do not continue to test the system. This may lead to aeration of the oil and return a false value. To end the oil level check, release the throttle pedal and return to the Vehicle info menu by moving the menu stalk back.
Topping up the engine oil
WARNING: If the engine is stopped due to the Eco Start-Stop System you should be aware that the engine may restart without warning.
WARNING: The engine must be switched off before carrying out the engine oil top-up process.
- Open the rear luggage compartment.
- Unscrew the engine oil filler cap.
- Top up with the correct quantity of engine oil.
NOTE: Do not overfill the oil. If the total oil filled is greater than or equal to 8.0 litres and the Driver Display still displays a low oil level, do not continue to add more oil, contact your McLaren retailer.
ENVIRONMENTAL: When topping up, take care not to spill any oil. Oil must not be allowed to escape into the soil or waterways.
NOTE: Wait two minutes to allow oil to flow from the filler tube to the tank. This will ensure an accurate oil level reading. - Check the Driver Display to ensure level is correct.
NOTE: If you have inadvertently overfilled the engine with oil, you must have any excess removed at your McLaren retailer. The engine or the catalytic converter could be damaged. - Refit the engine oil filler cap.
