2023 Honda Odyssey Oil Capacity & Filter Specs

The 2023 Honda Odyssey equipped with the 3.5L V6 engine requires 5.7 US quarts (5.4 liters) of 0W-20 synthetic oil when replacing both the oil and the oil filter. As an ASE-certified master technician, I highly recommend verifying your fluid levels after the initial fill and warm-up, as the J35 V6 engine thrives on precise maintenance. Below is the complete technical reference for your 2023 Odyssey's oil change.

Quick Answer: Specs & Part Numbers

Before you crawl under the van, here is a quick cheat sheet with all the capacities and part numbers you need:

• Oil Capacity (with filter): 5.7 US quarts (5.4 L)
• Recommended Oil Weight: 0W-20 Full Synthetic
• Oil Specification: API SP / ILSAC GF-6A (Look for the API Starburst certification mark)
• OEM Oil Filter: Honda 15400-PLM-A02 (or 15400-PLM-A01)
• Aftermarket Filters: Fram XG7317 (Ultra Synthetic), Wix 51356, Mobil 1 M1-110A

Capacity by Engine Option

For the 2023 model year, Honda simplified the powertrain offerings. All trims of the Odyssey come equipped with the same tried-and-true 3.5-liter naturally aspirated V6 engine (J35Y6).

Oil Change Interval

The 2023 Honda Odyssey utilizes the built-in Honda Maintenance Minder system to calculate oil life based on engine operating conditions, temperature, and driving habits. However, here are the general guidelines:

• Normal Driving Duty: The Maintenance Minder will typically illuminate the wrench icon indicating 15% oil life between 7,500 and 10,000 miles (or roughly 12 months).
• Severe Driving Duty: If you frequently drive in stop-and-go traffic, idle extensively, tow, or drive in extreme temperatures/dusty conditions, expect the system to alert you closer to the 5,000-mile mark (or 6 months). Even if the light does not come on, do not exceed 12 months between changes.

Drain Plug Torque & Crush Washer

• Drain Plug Torque: 29 lb-ft (39 Nm)
• Drain Plug Size: 17mm socket/wrench
• Crush Washer: 14mm aluminum (Honda Part # 94109-14000)

Crucial Note: Never reuse the aluminum crush washer. Always install a new 14mm washer with the flat side facing the oil pan and torque the plug properly to 29 lb-ft to prevent leaks and stripped threads in the aluminum oil pan.

How to Change the Oil

1. Prepare the Vehicle: Park on a level surface, engage the parking brake, and raise the front of the vehicle safely using ramps or a jack and jack stands.
2. Drain the Oil: Remove the oil filler cap under the hood to improve flow. Locate the 17mm drain plug on the rearward-facing side of the oil pan. Remove it and allow the old oil to drain completely into a catch pan.
3. Replace the Filter: Locate the oil filter (accessed from underneath, near the passenger side of the engine block). Place a catch pan directly below it to catch residual oil. Remove the old filter, wipe the mating surface clean, lubricate the new filter's rubber O-ring with fresh oil, and install it hand-tight (typically 3/4 to 1 turn after the gasket makes contact).
4. Reinstall Drain Plug: Install a new 14mm crush washer on the drain plug. Thread it in by hand, then torque to 29 lb-ft.
5. Refill and Check: Pour 5.7 quarts of 0W-20 synthetic oil into the engine. Replace the filler cap. Start the engine and let it run for a minute while checking for leaks underneath. Shut the engine off, wait 3-5 minutes, and check the dipstick to ensure the oil level is at the upper mark.
6. Reset Maintenance Minder: Turn the ignition on (engine off). Use the steering wheel controls to navigate to the Maintenance menu, select Oil Life, and hold the reset button until it resets to 100%.

Common Issues / Tips for the 2023 Odyssey

• Variable Cylinder Management (VCM): The J35 engine uses VCM to deactivate cylinders for fuel economy. While much improved in this generation, older VCM systems were notorious for oil consumption. It is still highly recommended to check your oil level on the dipstick every 1,000 miles.
• Filter Location Mess: The oil filter sits directly above subframe components. When removing the filter, oil often drips onto the frame rail. Use a form-a-funnel or cover the frame with aluminum foil before loosening the filter to save yourself a massive cleanup job.
• Direct Injection Dilution: The 3.5L is direct-injected. If you make short trips where the engine doesn't reach full operating temperature, fuel can dilute the oil. Following the Maintenance Minder severe schedule helps mitigate this wear.
