Method Measuring Oil Consumption, 850

This method determines a car's oil consumption. The method entails measuring the oil using the dipstick, before and after the customer drives a controlled distance of 2,000 km (1,200 miles +/- 1O0). This provides a satisfactory initial indication of oil consumption. In order to achieve as accurate a result as possible, you should drive the car on the road for about 20 minutes (not idling) to warm up the engine before making note of the oil level or draining the oil. To make sure that the oil in the engine during the control period has been approved by Volvo, change the oil and replace the oil filter. Also replace the air filter before performing any measurements.

When measuring/weighing the oil, the car should be on a level surface and in the same place both before and after driving the controlled distance.

Method:

- Change oil, replace oil filter and air filter. The oil must be of a type that is approved by Volvo.

- Drive the car on the road for 20 minutes to warm up the engine, bringing the temperature of the oil up to normal operating temperature.

- Switch off the engine and leave it off for 15 minutes.

- Check the oil level. If necessary, fill up oil if the level is below the minimum line on the dipstick.

- Run the engine for 5 minutes to mix the existing and added oil.

- Leave the engine off for 15 minutes and then take a note of the oil level on the dipstick. Note down the distance driven and information about the vehicle on the enclosed form on page 8.

Drive the car for 2,000 km (1,200 miles +/-1OO) or until its oil level has fallen to the minimum line on the dipstick.

The same filter should stay on the engine during the entire test.

After driving the controlled distance but before checking the oil level on the dipstick again:

- Drive the car on the road for 20 minutes to warm up the engine, bringing the temperature of the oil up to normal operating temperature.

- Switch off the engine and leave it off for 15 minutes.

- Take measurements on the dipstick with a sliding calliper, for example, and note down the oil level on the enclosed form.

If the measurement establishes abnormal oil consumption, the engine may need corrective action according to corrective Action Section in this bulletin.
