2022 International MV Oil Capacity & Filter Guide

The 2022 International MV requires between 15 and 24 quarts of engine oil depending on whether it is equipped with the Cummins B6.7 or the Cummins L9 engine. As a versatile medium-duty truck, the MV series relies on these proven diesel powerplants, which demand high-quality heavy-duty diesel engine oil for maximum uptime and longevity.

Quick answer

• Oil Capacity: 15–16 quarts (Cummins B6.7) or 24 quarts (Cummins L9) including filter.
• Recommended Weight: 15W-40 (above 5°F) or 5W-40/10W-30 (for colder climates/better fuel economy).
• Oil Specification: API CK-4 / Cummins CES 20086.
• Oil Filter (Cummins B6.7): OEM Fleetguard LF16035 (or LF3970). Aftermarket cross-references: Wix 57620, Fram PH3976A, Donaldson DBL7300.
• Oil Filter (Cummins L9): OEM Fleetguard LF3000 (or LF9009). Aftermarket cross-references: Wix 51748, Fram PH8691.

Capacity by engine option

*Note: Always check the dipstick after a refill. Pan sizes can occasionally vary slightly based on specific chassis upfitting or PTO applications.

Oil change interval

Heavy-duty truck intervals depend heavily on how the truck is used, engine idle time, and gross vehicle weight.

• Normal Duty (Highway / Light Vocational): Replace oil and filter every 15,000 to 20,000 miles, or 500 hours, or 6 months (whichever comes first).
• Severe Duty (High Idle / Heavy Vocational / City P&D): Replace oil and filter every 10,000 miles, or 350 to 400 hours, or 6 months.

Pro-Tip: We highly recommend implementing an Oil Analysis Program (e.g., Blackstone Labs) to dial in your fleet's exact drain intervals based on wear metals and TBN (Total Base Number) depletion.

Drain plug torque

• Torque Spec: 44 ft-lbs (60 Nm) for standard Cummins B6.7 and L9 oil pans.
• Crush Washer: Always inspect and replace the copper or bonded seal washer on the drain plug. A deformed washer will cause annoying chassis leaks.

How to change the oil

1. Warm up the engine: Run the engine until it reaches operating temperature to ensure the oil drains quickly and suspends soot/contaminants.
2. Drain the oil: Position a large-capacity catch pan (at least 7 gallons) under the drain plug. Remove the plug and let it drain completely.
3. Replace the filter: Using a heavy-duty strap wrench, remove the old oil filter. Warning: These hold a lot of oil—have your drain pan ready.
4. Prep the new filter: Pre-fill the new Fleetguard filter with fresh oil to prevent dry starts. Lubricate the rubber gasket with clean oil.
5. Install the filter: Spin the new filter on until the gasket makes contact, then tighten 3/4 to 1 full turn (or follow the instructions printed on the filter body).
6. Reinstall drain plug: Install a new crush washer and torque the plug to 44 ft-lbs.
7. Refill and check: Pour the specified amount of API CK-4 oil into the engine. Start the truck, check for leaks, and monitor oil pressure. Shut down, wait 10 minutes, and verify the level on the dipstick.

Common issues / tips

• Low Ash Oil is Mandatory: You must use an oil rated API CK-4. Using older specs (like CI-4) or non-approved additives will quickly poison the Diesel Particulate Filter (DPF) and cause costly aftertreatment system failures.
• Filter Upgrades: Fleetguard filters utilizing "Stratapore" media (like the LF16035 instead of the cellulose LF3970) offer significantly better filtration for extended service intervals.
• High Idle Hours: Many MVs are used as bucket trucks, tow trucks, or dump trucks. If your PTO runs constantly, base your maintenance on engine hours rather than mileage.
