What oil does an Acura Rl take?
The oil specification for an Acura RL depends on the model year and engine, but most RLs use synthetic oil in the common Honda/Acura ranges: earlier models typically call for 5W-30, while later models often use 5W-20. Always verify the exact grade for your vehicle in the owner’s manual or on the oil fill cap.
Oil recommendations by RL generation
The RL was produced in two main generations with different engines, which influences the recommended oil grade. The following guidelines reflect typical factory recommendations, but your exact specification may vary by year and region.
- 2005–2008 RL (3.5L V6): synthetic 5W-30 is commonly recommended, with an oil capacity around 5.5 quarts (including a replacement filter).
- 2009–2012 RL (3.7L V6): synthetic 5W-20 is commonly recommended, with an oil capacity around 5.5 quarts (including a replacement filter).
These recommendations are intended as a general guide. For precise grade, viscosity, and capacity, consult your owner’s manual or the under-hood oil cap for the exact specification used by your VIN.
How to confirm the exact spec for your car
To ensure you use the correct oil, follow these steps before an oil change or when in doubt:
- Check the owner’s manual, which lists the exact oil grade and capacity for your model year and engine.
- Look at the oil fill cap on the engine; many caps indicate the required viscosity (e.g., 5W-30 or 5W-20).
- Refer to the service reminder sticker in the engine bay or the vehicle’s maintenance history from Honda/Acura’s service portal, which may specify the recommended oil type.
- When in doubt, call an Acura dealer or a certified mechanic with your VIN to confirm the correct specification.
Regardless of the year, using a high-quality synthetic engine oil that meets or exceeds the API/SACE/ILSAC specifications recommended by Acura will help maintain engine protection and efficiency. If you drive in extreme temperatures or with heavy towing or aggressive driving, you may need to adapt the grade within the recommended range as advised by the dealer.
Additional considerations
Climate and driving conditions can influence the optimal viscosity within the recommended range. In very cold climates, some owners opt for the lighter end of the recommended range (e.g., 5W-20), while extremely hot or heavy-use conditions might justify the higher end (e.g., 5W-30). Always verify with official guidance for your specific vehicle and region.
Summary
In short, an Acura RL typically takes synthetic oil, with 5W-30 common for older 3.5L models and 5W-20 common for later 3.7L models. The exact specification depends on the year and engine, so always check the owner’s manual or the oil cap to confirm the correct viscosity and capacity for your vehicle. Regular use of the correct oil helps preserve engine performance and longevity.
