Engine oil

To check and refill engine oil

Petrol-powered vehicles

Diesel-powered vehicles

The engine oil used has a significant effect on the engine’s performance, service life and startability.

Be sure to use oil of the recommended quality and appropriate viscosity.

All engines consume a certain amount of oil during normal operation. Therefore, it is important to check the oil level at regular intervals or before starting a long trip.

1. Park the car on a horizontal surface.
2. Switch off the engine.
3. Wait a few minutes.
4. Remove the dipstick and wipe it with a clean cloth.
5. Reinsert the dipstick as far as it goes.
6. Remove the dipstick and read the oil level, which should always be within the range indicated.
7. If the oil level is below the specified limit, remove the cap located on the cylinder head cover and add enough oil to raise the level to within the specified range. Do not overfill to avoid engine damage. Be sure to use the specified engine oil and do not mix various types of oil.
8. After adding oil, close the cap securely.
9. Confirm the oil level by repeating step 4 to 6.

CAUTION

• In diesel-powered vehicles, when burning away and removing soot accumulated in the DPF, fuel can mix with the engine oil and an increase in the engine oil level may occur. This does not indicate an abnormality.

However, if the engine oil level is at or over the “X” mark (B) on the engine oil dipstick (A), change the engine oil.

NOTE

• The engine oil will deteriorate rapidly if the vehicle is subjected to severe conditions, requiring earlier oil replacement.

Please refer to the maintenance schedule.

• For information on how to dispose of used engine oil, refer to page 05.

Recommended engine oil viscosity

Petrol-powered vehicles

• Select engine oil of the proper SAE viscosity number according to the atmospheric temperature.

SAE 0W-20, 0W-30, 5W-30, and 5W-40 engine oils can only be used if they meet ACEA A3/B3, A3/B4 or A5/B5 and API SM specifications.

• Use engine oil conforming to the following classification:

• API classification: “For service SM”
• ILSAC certificated oil
• ACEA classification:

“For service A1/B1, A3/B3, A3/B4 or A5/B5”

• Use of additives is not recommended since they may reduce the effectiveness of additives already included in the engine oil. It may result in failure of the mechanical assembly.

Diesel-powered vehicles

• Select engine oil of the proper SAE viscosity number according to the atmospheric temperature.

• Use engine oil conforming to the following classification:

• ACEA classification:

“For service C1, C2, C3 or C4”

• JASO classification:

“For service DL-1”

If those classifications are not available, contact a MITSUBISHI MOTORS Authorized Service Point.

NOTE

• Use of additives is not recommended since they may reduce the effectiveness of additives already included in the engine oil. It may result in failure of the mechanical assembly.
