Most recent Honda Ridgelines run on a low-viscosity synthetic oil, typically 0W-20, while older first‑generation models generally use 5W‑20. Always verify the exact specification for your year in the owner’s manual or on the engine oil fill cap.
Oil grade and viscosity by generation
Honda has used different recommendations for the Ridgeline’s two generations. The guidance below reflects common practice, but your specific year may vary. Always confirm with your manual or dealership if in doubt.
- First generation (2006–2014): The typical recommendation is 5W-20 engine oil for normal driving in a wide range of climates. Use an oil that meets API service standards and Honda’s requirements.
- Second generation (2017–present): The typical recommendation is 0W-20 engine oil for normal operation in most climates. If 0W-20 is unavailable, 5W-20 may be acceptable, but check the owner’s manual for your exact guidance.
Regardless of generation, use oil that meets API SN or newer and ILSAC GF standards, and consider a full synthetic or synthetic-blend for best protection and efficiency. Always check your specific model year’s manual or the oil cap for the exact grade.
Synthetic vs. conventional and standards
There are practical choices beyond viscosity. The following guidance helps you choose the right oil type while staying compliant with Honda’s specs.
- Synthetic 0W-20 is preferred for most second‑generation Ridgelines to maximize protection and fuel economy.
- If 0W-20 isn’t available, a high-quality synthetic blend or conventional 5W-20 that meets API SN or newer and ILSAC GF-5/GF-6 can be acceptable, but keep in mind that switch may affect oil-change intervals and performance.
Always prioritize oils that meet Honda’s certification and the API/ILSAC standards listed in your owner's manual, and revert to the manual if you’re mixing oil types for a temporary repair.
Oil capacity and change interval
Knowing how much oil your Ridgeline takes and when to change it helps prevent under- or over-filling. Exact values vary by engine and year, so use the manual for precision. The notes below give typical ranges and practices to expect.
- Oil capacity is generally around five quarts (with filter) for most Ridgeline engines; exact figures are provided in the owner’s manual for your year and trim.
- Oil-change interval under normal driving with synthetic oil is commonly about 7,500 miles (12,000 km) or 12 months, whichever comes first. Severe driving conditions or using conventional oil typically shorten this interval to around 3,750–5,000 miles (6,000–8,000 km) or 6 months, depending on conditions.
Always follow the maintenance schedule printed in your manual, and reset the oil-change light as instructed after every change.
How to verify the exact spec for your vehicle
Because model years and production changes can affect the recommendation, use these quick checks to confirm the right oil for your Ridgeline:
- Check the engine oil fill cap for the viscosity (for example, 0W-20 or 5W-20).
- Open the owner's manual and review the "Lubrication System" or "Engine Oil" section for the exact grade and standards.
- Ask your Honda dealer or service center if you’re unsure about any year-specific requirements.
Choosing the right oil helps preserve engine performance and long-term reliability. When in doubt, follow Honda’s official guidance for your exact year and engine code.
Summary
In short, most modern Honda Ridgelines use 0W-20 synthetic oil, especially in the second generation (2017–present). The first generation (2006–2014) typically calls for 5W-20. Always verify with your owner’s manual or the oil cap, and ensure the oil meets API and ILSAC standards. Use a high-quality synthetic or synthetic-blend oil and adhere to the recommended change intervals to keep your Ridgeline running smoothly.
