2020 Freightliner M2 106 – Oil Capacity & Filter

The 2020 Freightliner M2 106, when equipped with the popular Cummins B6.7 engine, typically requires 17.2 quarts (16.3 liters) of oil with a filter change.

Quick Answer

• Total Oil Capacity (with filter): 17.2 quarts (16.3 liters)
• Recommended Oil Weight: SAE 10W-30 or 15W-40 (depending on ambient temperature and duty cycle, consult your owner's manual for specific recommendations)
• Oil Type Spec: API CK-4 / API FA-4 (consult your owner's manual; FA-4 is for newer engines designed for lower viscosity, CK-4 is more common)
• Oil Filter (OEM): Cummins 5302194 or Daimler Trucks North America (DTNA) A0001802909
• Oil Filter (Aftermarket Cross-Reference):
  • Fram: PH11438
  • Wix: 57746
  • Mobil 1: M1-110A (Verify application, as Mobil 1 might not directly offer heavy-duty filters for all Cummins engines)

Capacity by Engine Option

While the Cummins B6.7 is the most common, other engine options may exist. Always verify your specific engine code.

Oil Change Interval

The oil change interval for your 2020 Freightliner M2 106 can vary significantly based on engine, oil type, fuel quality, duty cycle, and operating conditions. Always refer to your vehicle's owner's manual and engine manufacturer's recommendations.

• Normal Duty: Typically between 25,000 to 50,000 miles or 500-800 hours, whichever comes first. Some manufacturers allow extended drain intervals with oil analysis.
• Severe Duty: This includes frequent short trips, excessive idling, dusty conditions, extreme temperatures, or consistent heavy loads. Intervals may be reduced by 30-50% or more. Oil analysis is highly recommended for severe duty applications to optimize intervals.

Drain Plug Torque

For the Cummins B6.7 engine in the 2020 Freightliner M2 106, the oil drain plug torque specification is typically around 59 lb-ft (80 Nm). Always use a new crush washer or seal to prevent leaks. Verify the exact torque specification in your service manual, as discrepancies can occur due to variations in oil pan material or drain plug design.

How to Change the Oil

1. Warm Up Engine: Run the engine to operating temperature to allow oil to drain more easily.
2. Locate Drain Plug: Position a suitable oil drain pan beneath the oil pan drain plug. Ensure the pan can hold at least 20 quarts.
3. Remove Drain Plug: Carefully remove the drain plug and allow all oil to drain completely.
4. Replace Filter: Remove the old oil filter. Apply a thin coat of new oil to the gasket of the new filter. Install the new filter and tighten according to manufacturer specifications (usually hand-tight plus a quarter to half turn, or consult torque specs if provided).
5. Reinstall Drain Plug: Install the drain plug with a new crush washer and tighten to the specified torque.
6. Refill Oil: Slowly add the recommended amount and type of fresh engine oil through the oil fill cap, checking the dipstick frequently.
7. Check Level: Start the engine and run for a few minutes to circulate oil. Turn off the engine, wait a few minutes, and recheck the oil level on a level surface. Add more if necessary to bring it to the
