Capacity by engine option

Oil change interval

Normal Duty: For vehicles operating under typical conditions (highway driving, moderate loads), the recommended oil change interval can range from 25,000 to 50,000 miles or 500-800 hours, whichever comes first. Always refer to the specific engine manufacturer's recommendations in your owner's manual, as intervals can vary based on oil analysis and engine usage.

Severe Duty: Vehicles operating under severe conditions (frequent idling, heavy loads, extreme temperatures, dusty environments, frequent short trips) require more frequent oil changes. Intervals may be reduced to 15,000 to 25,000 miles or 250-500 hours. Advanced oil analysis programs can help optimize severe duty oil change intervals.

Drain plug torque

For the 2022 International LT, consult your specific engine's service manual for the exact drain plug torque specifications. Over-tightening can strip threads, and under-tightening can lead to leaks. Always use a new crush washer or drain plug gasket with each oil change to ensure a proper seal. Crush washer specifications will vary by engine model; consult your service manual.

How to change the oil

1. Warm up the engine: Drive the truck for 10-15 minutes or let it idle to bring the oil to operating temperature, ensuring it drains more easily.
2. Park and secure: Park the truck on a level surface, engage the parking brake, and chock the wheels. If lifting the truck, use proper jack stands.
3. Locate drain plug and drain the oil: Place a suitable oil drain pan beneath the drain plug. Carefully remove the drain plug and allow all the old oil to drain completely. Inspect the drain plug and replace the crush washer.
4. Replace the oil filter: Locate the oil filter(s). Using an oil filter wrench, remove the old filter(s). Apply a thin coat of new oil to the gasket of the new filter(s) and hand-tighten until snug, then typically an additional 1/2 to 3/4 turn (consult filter instructions). Do not overtighten.
5. Reinstall drain plug: Once oil has fully drained, reinstall the drain plug with a new crush washer and tighten to the manufacturer's specified torque.
6. Refill with new oil: Using a funnel, add the recommended type and amount of new engine oil. Start with a slightly lower amount than the maximum capacity, then check the dipstick.
7. 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 if necessary until the level is within the safe operating range.
8. Inspect for leaks: Check around the drain plug and oil filter for any signs of leaks.
9. Reset maintenance minder: If equipped, reset the oil life monitoring system according to the owner's manual.

Common issues / tips

• Oil Analysis: For fleet operators or owner-operators, regular oil analysis is highly recommended. This can provide valuable insights into engine health, identify potential issues early, and help optimize oil change intervals, potentially extending them safely.
• Genuine Filters: While aftermarket filters are available, many heavy-duty engine manufacturers recommend using genuine OEM oil filters to ensure optimal filtration and engine protection. Consult your engine manufacturer for their stance.
• Cold Weather Operation: If operating in consistently cold climates, consider using 10W-30 synthetic or synthetic blend oils that meet the required API specifications (CK-4 or FA-4) for improved cold starting and oil flow at low temperatures.
• DEF System Integration: Modern heavy-duty trucks like the International LT feature advanced emissions systems (like Selective Catalytic Reduction - SCR) that are sensitive to engine oil ash content. Ensure the oil used meets the specified API CK-4 or FA-4 requirements, as these are formulated to be low-ash and compatible with these systems.
