2025 International MV — Oil Capacity & Filter

The 2025 International MV takes between 16 and 32 quarts of 10W-30 or 15W-40 full synthetic or synthetic blend engine oil, depending on the engine. Always consult your owner's manual for the most accurate information.

Quick answer

• Oil capacity: 16-32 quarts (15.1-30.3 liters)
• Recommended oil weight: 10W-30 or 15W-40
• Oil type spec: API CK-4 / FA-4 (consult owner's manual for specific engine requirements)
• OEM oil filter part number: Consult dealer (varies significantly by engine and configuration)
• Aftermarket oil filter cross-references:
  • Fram: Consult Fram catalog or cross-reference tool
  • Wix: Consult Wix catalog or cross-reference tool
  • Mobil 1: Consult Mobil 1 catalog or cross-reference tool

Capacity by engine option

Always verify these specifications with your vehicle's owner's manual, as capacities and specifications can vary based on specific vehicle configuration, aftertreatment systems, and engine calibration.

Oil change interval

Normal Duty: For vehicles operating under typical conditions (e.g., highway driving, moderate loads, regular maintenance), the recommended oil change interval is generally 25,000 to 35,000 miles or 500-750 engine hours, whichever comes first. Many modern heavy-duty engines employ oil life monitoring systems that can extend or shorten this interval based on actual operating conditions and oil degradation.

Severe Duty: Vehicles operating under severe conditions (e.g., frequent short trips, extreme temperatures, heavy loads, dusty environments, extensive idling, or stop-and-go driving) require more frequent oil changes. In these cases, the interval may be reduced to 15,000 to 20,000 miles or 250-400 engine hours, or as indicated by the oil life monitoring system.

Always refer to your International MV owner's manual or maintenance schedule for precise oil change intervals for your specific application and engine.

Drain plug torque

Due to the wide variety of engine and oil pan configurations on the International MV, the drain plug torque specifications can vary significantly. Always consult your service manual or a professional technician for the exact torque specification for your specific engine.

Crush Washer: Most heavy-duty truck engines utilize an O-ring or a re-usable gasket on the drain plug, rather than a single-use crush washer. Inspect the O-ring or gasket for any signs of wear or damage and replace if necessary to prevent leaks.

How to change the oil

1. Preparation: Park the truck on a level surface, engage the parking brake, and ensure the engine is slightly warm but not hot. Gather your tools, new oil, new filter(s), drain pan, and rags.
2. Locate Drain Plug: Place the drain pan beneath the oil pan drain plug. Due to the size of the oil pan, a large-capacity drain pan is essential.
3. Drain Oil: Carefully remove the drain plug and allow all the old oil to drain completely. This can take some time due to the large volume.
4. Replace Filter(s): Locate the engine oil filter(s). Unscrew the old filter(s) and allow any remaining oil to drain. Apply a thin coat of new oil to the gasket of the new filter(s) and screw it on by hand until snug, then tighten an additional 3/4 to 1 full turn (refer to filter instructions for precise tightening).
5. Reinstall Drain Plug: Once all oil has drained, clean the drain plug and oil pan mating surface. Reinstall the drain plug and tighten it to the manufacturer's specified torque (consult service manual).
6. Refill Oil: Remove the oil fill cap and add the recommended amount and type of new engine oil. Use a funnel to prevent spills.
7. Check Level: After filling, replace the oil cap, start the engine, and let it run for a few minutes to circulate the new oil. Check for leaks around the drain plug and filter(s). Shut off the engine, wait a few minutes for the oil to settle, then check the oil level using the dipstick. Add more oil if necessary to reach the proper "full" mark.

Common issues / tips

• Oil Sampling: For fleet operators and individual owners pushing extended drain intervals, oil analysis is highly recommended. It can provide valuable insights into engine wear, oil condition, and contamination, helping to optimize maintenance schedules and prevent costly failures.
• Filter Quality: Always use high-quality oil filters that meet or exceed OEM specifications. Cheap filters may not provide adequate filtration, leading to accelerated engine wear.
• Aftertreatment System Compatibility: Ensure the engine oil specified is compatible with your vehicle's aftertreatment system (e.g., Diesel Particulate Filter - DPF, Selective Catalytic Reduction - SCR). Using the wrong oil can damage these expensive components.
• Engine Specifics: The International MV can be equipped with various Cummins or Navistar engines. Always confirm the specific engine in your truck before performing maintenance to ensure you use the correct oil capacity, type, and filter.
