2024 International MV Oil Capacity & Filter Specs

The 2024 International MV takes between 15 quarts (14.2 L) and 23.7 quarts (22.4 L) of oil, depending on whether it is equipped with the Cummins B6.7 or the larger Cummins L9 engine and the specific oil pan option ordered. As a medium-duty workhorse used for everything from delivery box trucks to dump applications, maintaining the proper oil level and specification is critical to keeping this truck on the road and out of the shop.

Quick answer

Here is the quick reference guide for the standard 2024 International MV equipped with the popular Cummins B6.7 engine:

• Oil Capacity: 15 to 17.5 quarts (14.2 to 16.5 L) with filter, depending on the oil pan configuration.
• Recommended Weight: 15W-40 (for temperatures above 5°F) or 5W-40 Synthetic (for extreme cold climates).
• Oil Specification: API CK-4 / Cummins CES 20086.
• OEM Oil Filter Part Number: Fleetguard LF3970.
• Aftermarket Cross-References: WIX 57349, Baldwin BT7349, Donaldson P558615 (Consult dealer for exact cross-reference matching your specific build sheet).

Capacity by engine option

The 2024 International MV series is powered by Cummins diesel engines. Because these are custom-ordered commercial chassis, the exact oil pan capacity can vary slightly based on clearance requirements. Always check your dipstick after the initial fill.

Oil change interval

Medium-duty diesel engines operate under different duty cycles than passenger vehicles. Service intervals are dictated by mileage, engine hours, or time—whichever comes first.

• Normal Duty (Highway / Light Delivery): Change the oil and filter every 15,000 miles, 500 engine hours, or 6 months.
• Severe Duty (Stop-and-Go, PTO use, Towing, Dusty Conditions): Change the oil and filter every 10,000 miles, 250 to 350 engine hours, or 6 months. High idle times significantly accelerate oil degradation.

Drain plug torque

• Drain Plug Torque: 37 ft-lbs (50 Nm) for both the Cummins B6.7 and L9 standard oil pans.
• Crush Washer Note: Always inspect and replace the copper or copper-composite crush washer on the drain plug. Reusing a deformed washer on a heavy-duty diesel engine is a common cause of persistent leaks under extreme vibration.

How to change the oil

Servicing a commercial truck like the International MV requires heavy-duty drain pans and appropriate safety gear.

1. Warm the Engine: Run the engine until it reaches operating temperature to suspend contaminants in the oil, then shut it down.
2. Drain the Oil: Position a high-capacity catch pan (at least 30-quart capacity) under the oil pan. Remove the drain plug and let the oil drain completely.
3. Replace the Filter: Using a heavy-duty filter wrench, loosen the oil filter. Carefully lower it (it will be heavy and full of oil). Wipe the filter housing base clean.
4. Install New Filter: Pre-fill the new oil filter with fresh oil to prevent a dry start. Lubricate the rubber gasket on the new filter with clean oil, thread it on until the gasket makes contact, and tighten 3/4 to 1 full turn by hand.
5. Reinstall Drain Plug: Install the drain plug with a new sealing washer and torque to 37 ft-lbs.
6. Fill and Verify: Fill the engine with the specified capacity of API CK-4 heavy-duty diesel oil. Start the engine, check for leaks, and monitor oil pressure. Shut it off, wait 15 minutes, and verify the final level on the dipstick.

Common issues / tips

When servicing the 2024 International MV, pay special attention to the Cummins emission systems and fuel filters. The B6.7 and L9 engines require simultaneous fuel filter changes (both the chassis-mounted water separator and engine-mounted filter) at every oil change interval to prevent high-pressure fuel pump failures. Furthermore, be cautious of overfilling the oil; excessive oil can cause foaming, leading to oil pressure drops and potential blow-by that can prematurely clog the Diesel Particulate Filter (DPF). Lastly, don't forget to grease the chassis, steering linkages, and driveline U-joints while you are under the truck draining the oil.
