Hyundai Tucson: Maintenance / Engine Oil. Checking the Engine Oil and Filter

Checking the Engine Oil Level

Engine oil is used for lubricating, cooling, and operating various hydraulic components in the engine. Engine oil consumption while driving is normal, and it is necessary to check and refill the engine oil regularly. Also, check and refill the oil level within the recommended maintenance schedule to prevent deterioration of oil performance.

Check the engine oil following the below procedure.

1. Follow all of the oil manufacturer’s precautions.

2. Make sure the vehicle is on the level ground in P (Park) with the parking brake applied.

3. Turn on the engine and warm the engine up until the coolant temperature reaches a constant normal temperature.

4. Turn off the engine, remove the oil filler cap and pull the dipstick out. Wait for 15 minutes for the oil to return to the oil pan.

5. Wipe the dipstick clean and re-insert it fully.

6. Pull the dipstick out again and check the level. The level should be between F (Full) and L (Low).

7. If the oil level is below the L, add enough oil to bring the level to F.

Use only the specified engine oil (Refer to the “Recommended Lubricants and Capacities” section in Chapter 10).

NOTICE

To prevent damage to your engine:

• Do not spill engine oil when adding or changing engine oil. Wipe off spilled oil immediately.
• The engine oil consumption may increase while you break in the new vehicle, and it should stabilize after driving 4,000 miles (6,000 km).
• The engine oil consumption may be affected by driving habits, climate conditions, traffic conditions, and oil quality. Inspect the engine oil level regularly and refill if necessary.

Checking the Engine Oil and Filter

• The lubrication, rust prevention, cooling, and cleaning effect of the engine oil will gradually degrade during its use. Have the engine oil and filter changed by an authorized HYUNDAI dealer according to the Oil Life Management System instructions or the Maintenance Schedule at the beginning of this chapter.
• To keep the engine in optimal condition, use the recommended engine oil and filter. If the recommended engine oil and filter are not used, replace them according to the Maintenance Schedule Under Severe Usage Conditions.
• The purpose of the maintenance schedule for engine oil replacement is to prevent oil deterioration and it is irrelevant to oil consumption. Check and refill engine oil regularly.

Information

If the oil pressure is low, due to insufficient engine oil, the Engine Oil Pressure () warning light illuminates. The enhanced engine protection system that limits the engine’s power, is activated and the Malfunction Indicator Lamp () illuminates. After sufficient engine oil is added, the Engine Oil Pressure warning light turns off and the engine power is no longer limited.

However, for gasoline 2.5 turbo engine, when the engine oil pressure is restored, the warning light and the enhanced engine protection system turns off after the engine is restarted.

WARNING

Allow the engine to cool before replacing the oil.
