Oil consumption

L90, and K7J or K7M

PROCEDURE FOR MEASURING OIL

CONSUMPTION

1 - Filling to the maximum level

Note:

The operation should be carried out with the engine warm after the fan assembly has cut in once.

Turn the engine off.

Wait 2 minutes for all the oil to flow into the oil sump.

Carry out a visual inspection using the dipstick.

Top up to the "MAX" mark.

Make a paint mark on both the filler plug and the sump drain plug in order to be able to check later that it has not been removed.

2 - Customer driving

Ask the customer to drive approximately 1240 miles (2000 km) in the vehicle without letting the oil level reach the "MIN" mark.

3 - Topping up

Note:

The operation should be carried out with the engine warm after the fan assembly has cut in once.

Turn the engine off.

Wait 2 minutes for all the oil to flow into the oil sump.

Carry out a visual inspection using the dipstick.

Top up to the "MAX" mark.

Note the quantity of oil added and the mileage covered since the last top-up to maximum level.

4 - Measurement of the oil consumption

Oil consumption = Quantity of topping up oil (in litres) / number of kilometres (in thousands).
