Oil Change Indicator System — Cummins Diesel

Your vehicle is equipped with an engine oil change indicator system. This system will alert you when it is time to change your engine oil by displaying the words “Oil Change Due” in your instrument cluster display. The engine oil change indicator system is duty cycle based, which means the engine oil change interval may fluctuate depending on your personal driving style.  Failure to change the engine oil per the maintenance schedule can result in internal engine damage.

An authorized dealer will reset the oil change indicator message after completing the scheduled oil change. If a scheduled oil change is performed by someone other than an authorized dealer, the message can be reset by referring to the steps described under “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.

Replace the engine oil and oil filter every 15,000 miles (24,000 km) or 12 months, or sooner if prompted by the oil change indicator system. Under no circumstances should oil change intervals exceed 15,000 miles (24,000 km) or 12 months, whichever comes first.

Note: 

• Under no circumstances should oil change intervals exceed 15,000 miles (24,000 km) or 12 months or 500 hours, whichever comes first.
• It is recommended that every 3,000 miles (4,800 km), check the engine oil level at least 30 minutes after a fully warmed engine is shut off. Checking the oil level while the vehicle is on level ground will improve the accuracy of the oil level reading. Add oil only when the level is at or below the ADD or MIN mark.
• Severe service (high ambient temperature, short trips, heavy loading, trailer towing, off-road, or law enforcement use) may reduce oil change intervals.

In ambient temperatures above 0°F (-18°C), we recommend you use 10W-30 engine oil that meets the manufacturer Material Standard MS-10902 and the API CK-4 engine oil
category is required. Products meeting Cummins® CES 20081 may also be used. The identification of these engine oils is typically located on the back of the oil container.
 
In ambient temperatures below 0°F (-18°C), we recommend you use 5W-40 synthetic engine oil that meets the manufacturer Material Standard MS-10902 and the API CK-4 engine oil category is required.
