Oil Change Interval

Honda recommends following the Maintenance Minder system in your vehicle, which will illuminate a "Service Due Soon" message (with a wrench icon) on your dashboard. This system dynamically calculates the oil life based on driving conditions and habits.

• Normal Duty: Typically, the Maintenance Minder will indicate an oil change is due between 7,500 and 10,000 miles or about 12 months, whichever comes first.
• Severe Duty: If you frequently drive in demanding conditions such as extreme temperatures, stop-and-go traffic, towing, or dusty environments, the Maintenance Minder may recommend an oil change closer to 3,000-5,000 miles or 6 months.

Always rely on your vehicle's Maintenance Minder system for the most accurate oil change guidance.

Drain Plug Torque

The drain plug for the 2021 Honda Odyssey should be torqued to 29 lb-ft (39 Nm). It is highly recommended to replace the crush washer with a new one (OEM part number 94109-14000) every time you change the oil to ensure a proper seal and prevent leaks.

How to Change the Oil

1. Gather your supplies: 0W-20 synthetic oil, new oil filter, new crush washer, drain pan, wrench for the drain plug, oil filter wrench, and rags.
2. Warm up the engine slightly, then turn it off.
3. Locate the oil drain plug on the oil pan beneath the vehicle. Place the drain pan underneath.
4. Using the appropriate wrench, carefully remove the drain plug, allowing the old oil to drain completely. Be cautious, as the oil may be hot.
5. Once the oil has drained, replace the crush washer with a new one and reinsert the drain plug. Torque it to 29 lb-ft (39 Nm).
6. Locate the oil filter. Place the drain pan underneath it, as some residual oil will drip out.
7. Use an oil filter wrench to loosen and remove the old oil filter.
8. Apply a small amount of new oil to the rubber gasket of the new oil filter. Screw on the new filter by hand until it's snug, then turn it an additional 3/4 to 1 full turn (or follow filter manufacturer instructions).
9. Remove the oil fill cap on top of the engine and pour in approximately 5.7 quarts of fresh 0W-20 synthetic oil.
10. Replace the oil fill cap, start the engine, and let it run for a few minutes. Check for any leaks around the drain plug and oil filter.
11. Turn off the engine, wait a few minutes for the oil to settle, then check the oil level on the dipstick. Add more oil if necessary to reach the "full" mark.
12. Reset the Maintenance Minder system if applicable.

Common Issues / Tips

• VCM (Variable Cylinder Management) Considerations: The 2021 Odyssey, like many Honda V6 engines, utilizes Variable Cylinder Management. Maintaining the correct oil level and using the proper 0W-20 synthetic oil is crucial for the longevity and proper operation of the VCM system. Some owners opt for more frequent oil changes, especially if they experience higher oil consumption, though this is less common with 0W-20 than older, thicker oils.
• Oil Consumption: While less prevalent in newer Honda V6 engines, always keep an eye on your oil level between changes. If you notice significant consumption, consult your dealer.
• Maintenance Minder Accuracy: Trust the Maintenance Minder. It's designed to optimize service intervals based on your actual driving conditions, helping to prevent premature wear and unnecessary maintenance.
• Genuine Honda Parts: While high-quality aftermarket filters are excellent, many enthusiasts prefer genuine Honda oil filters (15400-PLM-A02/A01) for their consistent quality and fit.
