Capacity by Engine Option

Always confirm the exact capacity with your vehicle's owner's manual, as capacities can vary slightly based on specific engine configurations and manufacturing updates.

Oil Change Interval

Normal Duty: Typically every 25,000 to 50,000 miles or 500-800 operating hours, whichever comes first.

Severe Duty: Often recommended every 15,000 to 25,000 miles or 300-500 operating hours. Severe duty conditions include frequent short trips, sustained low-speed operation, heavy towing, extreme temperatures, or dusty environments. It's always best to follow your vehicle's owner's manual and consider oil analysis for optimal drain intervals, especially in commercial applications.

Drain Plug Torque

Detroit DD5/DD8: The drain plug torque specification is typically between 50-60 ft-lbs (68-81 Nm). Always use a new crush washer or seal with each oil change to ensure a leak-free seal. Consult your owner's manual for the precise torque value for your specific engine.

How to Change the Oil

1. Warm Up Engine: Run the engine to bring the oil to operating temperature for easier draining.
2. Park Safely: Park on a level surface, engage the parking brake, and chock the wheels. If lifting the truck, use appropriate jacks and jack stands.
3. Locate Drain Plug: Place a large oil drain pan beneath the drain plug and an oil filter wrench on the oil filter.
4. Drain Oil: Carefully remove the drain plug and allow all old oil to drain completely. Inspect the drain plug and replace the crush washer.
5. Replace Filter: Remove the old oil filter. Apply a thin coat of new oil to the gasket of the new filter before installing. Hand-tighten until snug, then turn an additional 1/2 to 3/4 turn (or as specified on the filter/in manual).
6. Refill Oil: Reinstall the drain plug and tighten to the specified torque. Fill the engine with the recommended type and amount of new oil.
7. Check Level: Start the engine and let it run for a few minutes to circulate the oil. Shut off the engine, wait a few minutes, then check the oil level with the dipstick. Top off if necessary.
8. Dispose: Properly dispose of used oil and filter at an authorized recycling center.

Common Issues / Tips for this Generation

• DPF System Care: The 2019 Freightliner M2 106, especially with modern diesel engines, is equipped with a Diesel Particulate Filter (DPF). Using the correct API CK-4 or ACEA E9 oil specification is crucial for the longevity and proper function of the DPF system. Incorrect oil can lead to DPF clogging and costly repairs.
• Regular Oil Analysis: For commercial operators, implementing a regular oil analysis program is highly recommended. This can help optimize oil drain intervals, identify potential engine issues early, and extend engine life.
• Fuel Dilution: Be aware of potential fuel dilution, especially in trucks used for short-haul or stop-and-go operations. Oil analysis can detect this issue, which can degrade oil quality and reduce engine protection.
• Coolant Leaks: Keep an eye on coolant levels. Internal coolant leaks can contaminate engine oil, leading to severe engine damage. A milky appearance on the dipstick is a tell-tale sign of coolant in the oil.
• Engine Specifics: The Freightliner M2 106 is a versatile platform, and engine options can vary significantly. Always refer to your specific truck's owner's manual or consult Freightliner documentation for the most accurate and up-to-date maintenance information regarding your exact engine model.
