Most current Honda Ridgeline models require SAE 0W-20 full-synthetic motor oil, while older first-generation Ridgelines typically call for SAE 5W-20, with 5W-30 sometimes recommended in very hot climates. Always verify your exact specification in the owner’s manual or with a Honda dealer.
Oil requirements by generation
Below is a concise, generation-specific guide to the recommended viscosity and oil type for Ridgeline engines.
- Second-generation Ridgeline (2017–present): SAE 0W-20, full-synthetic motor oil recommended by Honda.
In brief, modern Ridgelines rely on 0W-20 full synthetic oil for optimal protection and fuel efficiency.
- First-generation Ridgeline (2006–2014): SAE 5W-20 is typically recommended; 5W-30 may be used in very hot climates if advised by Honda’s official guidance or dealer.
Overall, the 1st-gen Ridgeline commonly used 5W-20, with 5W-30 as an alternative in certain climates; always check the specific year’s manual for exact guidance.
Choosing oil type: Synthetic vs conventional
Honda generally aligns with using synthetic or synthetic-blend oils for Ridgeline engines, especially for 0W-20 in the newer generation. If you opt for conventional oil, ensure it meets the vehicle’s API certification and viscosity requirements and be mindful that oil-change intervals may differ from synthetic oils.
How to verify the exact specification for your vehicle
To be certain, consult your owner’s manual, check the vehicle’s VIN in official Honda resources, or ask a Honda service advisor. Always use a reputable oil that matches the recommended viscosity and API/service-grade requirements for your model year.
Summary
For the current Ridgeline lineup, expect 0W-20 full-synthetic oil. In the first generation (2006–2014), 5W-20 is commonly specified, with 5W-30 as an alternative in hotter environments. Climate, model year, and official manuals determine the exact choice, so always confirm with your documentation or a dealer. Regular oil changes with the correct grade help protect the V6 engine and maintain performance.
