Capacity by engine option

Oil change interval

Chevrolet recommends following the Oil Life Monitoring System (OLMS) for optimal oil change intervals. This system takes into account various factors like driving conditions, temperature, and engine revolutions to determine the ideal time for an oil change. As a general guideline:

• Normal Duty: Typically, the OLMS will recommend an oil change between 7,500 and 10,000 miles, or every 12 months, whichever comes first.
• Severe Duty: Vehicles subjected to severe driving conditions (e.g., frequent short trips, extreme temperatures, towing, dusty environments, heavy city driving) may require more frequent oil changes, possibly between 3,000 and 5,000 miles, or every 6 months. Always defer to the OLMS and your owner's manual recommendations.

Drain plug torque

The engine oil drain plug on the 2025 Chevrolet Tahoe typically requires a torque of 18 lb-ft (24 Nm). Always use a new crush washer with each oil change to ensure a proper seal and prevent leaks. Consult your owner's manual for the most accurate and up-to-date specification.

How to change the oil

1. Gather Supplies: New oil, oil filter, drain pan, wrench for drain plug, oil filter wrench, funnel, new crush washer, rags, jack and jack stands (if needed).
2. Warm Up Engine (Optional): Run the engine for a few minutes to warm the oil, allowing it to drain more easily. Be cautious, as the engine and oil will be hot.
3. Lift and Secure Vehicle: Safely raise the front of the Tahoe using a jack and secure it with jack stands.
4. Locate Drain Plug: Place the drain pan beneath the oil pan, then carefully remove the drain plug with a wrench. Allow all the old oil to drain completely.
5. Replace Drain Plug: Install a new crush washer on the drain plug and reinsert it, tightening to the specified torque of 18 lb-ft (24 Nm).
6. Remove Old Oil Filter: Position the drain pan under the oil filter. Use an oil filter wrench to loosen and remove the old filter. Be prepared for additional oil to drain out.
7. Install New Oil Filter: Apply a thin film of new engine oil to the gasket of the new oil filter. Screw on the new filter by hand until snug, then tighten an additional 3/4 to 1 full turn, or as specified by the filter manufacturer.
8. Add New Oil: Carefully pour the recommended amount and type of new oil into the engine through the oil filler cap.
9. Check Oil Level: Start the engine and let it run for a minute to circulate the oil. Turn off the engine and wait a few minutes for the oil to settle. Check the oil level on the dipstick and add more if necessary.
10. Inspect for Leaks: Check the drain plug and oil filter for any signs of leaks.

Common issues / tips

• Oil Consumption: Modern engines can sometimes consume a small amount of oil between changes. Regularly check your oil level with the dipstick and top off as needed.
• Dexos1 Gen 3: Ensure you are using oil that specifically meets the Dexos1 Gen 3 specification, as this is crucial for engine longevity and warranty compliance. This specification supersedes older Dexos classifications.
• Filter Quality: Always use a high-quality oil filter from a reputable brand to ensure proper filtration and engine protection. Consult your dealer for the OEM filter part number, or utilize reliable aftermarket cross-references.
• Owner's Manual: Your owner's manual is the ultimate source for all specifications and procedures. Always refer to it for the most accurate and up-to-date information regarding your specific vehicle.
