Abnormally High Oil Consumption

If a customer complains that the oil consumption is abnormally high, a few basic checks should be carried out first before taking further action such as a test drive or carrying out any work on the engine:

- Ask the customer questions about the driving conditions (see "Causes of high oil consumption" on next page).

- Check if there is any oil leakages

- Check that the crankcase ventilation is not blocked

- Check that the dipstick must be pushed all the way in order for the correct oil volume reading to be given.
