What you need for an oil change
Before you begin an oil change, gather the tools and supplies you’ll need to complete the job safely and cleanly.
- 4.5 quarts of 0W-20 synthetic oil
- New oil filter compatible with the 3.5L V6 (J35)
- Oil filter wrench
- Drain pan capable of holding several quarts
- Funnel
- Rags or shop towels, gloves
- Jack and stands or ramps
- New drain plug washer (if required)
Having these items ready ensures a smooth, clean oil change and helps prevent spills.
Steps to perform a basic oil change
Here are the general steps to replace the oil on a 2019 Odyssey. Follow the vehicle’s manual for torque specs and safety precautions.
- Warm up the engine briefly, then park on level ground and engage the parking brake.
- Raise the front of the vehicle on ramps or jack stands if needed for access; secure it safely.
- Place the drain pan under the oil pan and remove the drain plug; let used oil drain completely.
- Remove the old oil filter, drain any residual oil, and prepare the new filter by lightly coating its seal with fresh oil.
- Install the new oil filter by hand until snug; avoid over-tightening.
- Replace the drain plug with a new washer if required, and tighten to the manufacturer’s specification.
- Pour in 4.5 quarts of 0W-20 oil using a funnel, then check the level with the dipstick.
- Start the engine, run for a minute, then turn off and recheck for leaks. Check the oil level again and top up if needed.
- Dispose of used oil and the old filter at an appropriate recycling facility.
If you’re not comfortable performing an oil change yourself, a professional service can perform it quickly while ensuring proper disposal of waste oil.
Checking level and disposal considerations
After an oil change, double-check the level and observe for leaks. Properly dispose of used oil and filter in accordance with local regulations to protect the environment.
In all cases, refer to the owner’s manual for precise guidance tailored to your vehicle’s trim, climate, and service history.
