The standard answer is to use 5W-20 motor oil that meets API SN or newer, preferably synthetic or synthetic-blend, and to change it with a new filter according to Honda’s maintenance schedule. The typical fill is about 5 quarts.
For more detail: the 2010 Odyssey uses a 3.5-liter V6 and Honda generally specifies 5W-20 as the standard viscosity, with API SN or newer and ILSAC GF-5 or newer. Use a high-quality oil that meets those specs—Honda Genuine Motor Oil or a reputable aftermarket brand—and consider synthetic or synthetic-blend for longer intervals and easier cold starts. Always consult the owner's manual or your dealer for climate-specific guidance and never exceed the recommended viscosity range. After adding oil, recheck the level with the dipstick to ensure proper fill.
Oil specifications for the 2010 Odyssey
Here are the oil specifications to follow for the 2010 Odyssey's V6 engine.
- Viscosity: 5W-20 is the standard recommended grade for the 3.5L V6.
- Quality and certifications: API SN or newer; ILSAC GF-5 or newer.
- Brand/approval: Honda Genuine Motor Oil or a top-tier aftermarket oil that meets API SN and ILSAC GF-5 or newer.
- Oil type: Synthetic or synthetic-blend is acceptable; conventional oil is generally not preferred but may be allowed if specifically recommended by the manual.
- Capacity: About 5 quarts with a new filter; always verify the exact capacity in the owner's manual and on the dipstick after pouring.
Bottom line: for most drivers, use 5W-20 API SN+ synthetic or synthetic-blend oil, sourced from a reputable brand, and fill to roughly 5 quarts with the oil filter changed. Check the manual for any climate-specific allowances.
Maintenance intervals and practical tips
Before listing the guidance, consider how you’ll manage oil changes and maintenance reminders.
- Maintenance Minder guidance: The Odyssey uses Honda’s Maintenance Minder system to indicate when service is due, including oil changes. Follow the indicator rather than a fixed mileage alone.
- Oil change intervals: With conventional oil, expect about 5,000 miles (about 8,000 kilometers) or six months, whichever comes first. With synthetic or synthetic-blend oil, intervals often extend to roughly 7,500–10,000 miles (12,000–16,000 kilometers) or as indicated by the Maintenance Minder, depending on driving conditions.
- Topping up and level checks: If you need to top up between changes, use the same viscosity (5W-20) and do not exceed the maximum oil level on the dipstick. Recheck after the engine runs and sits for a moment.
- Oil filters: Use a quality oil filter compatible with the 3.5L V6 and preferably one endorsed by Honda or the same-brand standard that meets the oil spec.
In short, adhere to the Maintenance Minder, use 5W-20 oil that meets API SN or newer (synthetic or synthetic-blend preferred), and perform oil changes on schedule to protect the engine over the long term.
Summary
For a 2010 Honda Odyssey, the recommended oil is 5W-20 that meets API SN or newer, preferably in a synthetic or synthetic-blend formulation. Use Honda Genuine Motor Oil or a top-tier brand that meets the same specs, with about 5 quarts of oil plus a new filter. Follow the Maintenance Minder to determine exact changing intervals, and always consult the owner's manual for climate-specific guidance. Regular, quality oil changes help ensure reliable performance and engine longevity.
