Capacity by Engine Option

For the 2023 International MV Series, the primary engine is the Cummins B6.7 diesel. Variations in oil capacity are not typically found for this engine in different MV series configurations.

Oil Change Interval

The oil change interval for your 2023 International MV Series with the Cummins B6.7 engine can vary significantly based on operating conditions and duty cycle. Always refer to your vehicle's owner's manual and maintenance schedule for the most accurate information.

• Normal Duty: Typically 20,000 to 30,000 miles or 500 hours, whichever comes first.
• Severe Duty: This includes frequent short trips, extensive idling, prolonged operation in dusty conditions, or heavy hauling. Intervals may be reduced to 10,000 to 15,000 miles or 250-300 hours.

Modern diesel engines, like the Cummins B6.7, often utilize oil life monitors that take into account various factors to determine the optimal oil change interval. Follow the recommendations of the oil life monitoring system if your vehicle is equipped with one.

Drain Plug Torque

The drain plug for the Cummins B6.7 engine in the 2023 International MV Series typically requires a torque of 59 lb-ft (80 Nm). Always use a new crush washer or seal with each oil change to ensure a leak-free seal. Consult your service manual for the exact specification for your vehicle.

How to Change the Oil

Changing the oil on a heavy-duty truck like the International MV Series requires proper equipment and safety precautions. If you are not comfortable performing this procedure, it is best left to a qualified technician.

1. Warm Up Engine: Drive the truck for a few minutes to bring the oil to operating temperature, which helps it drain more easily.
2. Park Safely: Park the truck on a level surface, engage the parking brake, and block the wheels.
3. Locate Drain Plug: Place a large drain pan capable of holding over 17 quarts under the oil pan drain plug. The oil pan is typically located on the bottom of the engine.
4. Drain Oil: Carefully remove the drain plug with the appropriate wrench. Be cautious as the oil will be hot.
5. Replace Filter: While the oil is draining, locate and remove the old oil filter. Have a new filter ready. Apply a thin film of fresh oil to the gasket of the new filter before threading it on. Hand-tighten until snug, then turn an additional 3/4 to 1 full turn (or follow filter manufacturer's instructions).
6. Reinstall Drain Plug: Once the oil has completely drained, install a new crush washer on the drain plug and reinstall it, tightening to the specified torque of 59 lb-ft (80 Nm).
7. Add New Oil: Remove the oil filler cap (typically on top of the engine) and carefully pour in the new 15W-40 CK-4 heavy-duty diesel oil. Start with about 15 quarts, then check the dipstick.
8. Check Oil Level: Start the engine and let it run for a few minutes to circulate the new oil. Shut off the engine, wait a few minutes for the oil to settle, then check the dipstick. Add more oil as needed until the level is within the safe operating range.
9. Inspect for Leaks: Check around the oil drain plug and oil filter for any signs of leaks.
10. Reset Maintenance Reminder: Reset the oil life monitor or maintenance reminder system according to your vehicle's instructions.

Common Issues / Tips for this Generation

• DEF System Maintenance: While not directly oil-related, proper Diesel Exhaust Fluid (DEF) system maintenance is crucial for the overall health and emissions compliance of your Cummins B6.7 engine. Neglecting it can impact engine performance and longevity.
• Fuel Filter Changes: Regular fuel filter changes are just as important as oil changes for diesel engines. Consult your maintenance schedule for recommended intervals to protect your fuel injection system.
• OEM Parts: While aftermarket filters are available, many operators prefer OEM (Original Equipment Manufacturer) oil filters for heavy-duty applications to ensure optimal fitment and filtration performance. If using aftermarket, ensure they meet or exceed OEM specifications.
• Regular Inspections: Due to the demanding nature of commercial vehicle operation, regular visual inspections of belts, hoses, and fluid levels between scheduled maintenance can help identify potential issues before they become major problems.
