The 2008 Honda Odyssey uses 5W-20 engine oil, with a total capacity of about 5.5 quarts when a new filter is included.
In this article we outline the correct viscosity, typical capacity, and the oil options you can use—from conventional to synthetic—so you can choose the right setup for your vehicle and climate. We also cover practical tips for ensuring a proper oil change and maintenance schedule.
Oil specification and capacity
The Odyssey's 3.5-liter V6 is designed to operate with 5W-20 motor oil under most conditions. When changing the oil, replace the oil filter and use oil that meets the vehicle’s certification requirements. The engine’s oil capacity with a new filter is approximately 5.5 quarts.
Common oil choices you’ll encounter that meet the 5W-20 specification include conventional, synthetic blend, and full synthetic formulations. Any of these can be used as long as they are 5W-20 and meet the appropriate industry standards.
Options you may consider:
- 5W-20 conventional motor oil
- 5W-20 synthetic blend motor oil
- 5W-20 full synthetic motor oil
After completing an oil change, ensure the oil filter is properly installed, the sump is filled to the recommended level, and dispose of used oil responsibly. If your Odyssey is equipped with a Maintenance Minder, reset it according to the owner’s manual to track future changes.
Choosing between conventional, synthetic blend, or full synthetic
Conventional 5W-20 is typically the most affordable option and is adequate for normal driving in moderate climates. Synthetic blends offer improved protection and better performance across a wider range of temperatures, while full synthetic oils provide the highest level of protection and can offer longer intervals between changes, especially under demanding driving conditions. Any of these can be appropriate as long as they meet the 5W-20 specification and are compatible with your engine.
Practical notes
Always double-check the exact specification in your vehicle’s owner’s manual or with a Honda dealer, since regional recommendations can vary and service updates may change requirements. For extreme heat, cold, or heavy-use driving, a synthetic option can provide extra peace of mind.
Summary
In short, the 2008 Honda Odyssey takes 5W-20 motor oil with an approximate capacity of 5.5 quarts including the filter. You may choose conventional, synthetic blend, or full synthetic 5W-20, as long as the oil meets the appropriate standards and the level is maintained according to the vehicle’s maintenance schedule. Always consult the owner’s manual or a dealer for the most precise guidance for your specific vehicle and climate.
