What kind of oil does an Acura RLX take?
The Acura RLX uses synthetic 0W-20 motor oil.
For most model years of the RLX (2014–2020), Acura specifies a full-synthetic 0W-20 engine oil. The system uses about 5.7 quarts of oil with a new filter when performing an oil change. Always confirm with your owner's manual or maintenance minder, as the exact requirement can vary by engine variant, climate, and driving conditions.
Oil type, capacity and compatibility
Here are the core specifications to guide a standard RLX oil change.
- Recommended oil: synthetic 0W-20 that meets Honda/Acura specifications (OEM oil or approved equivalent).
- Oil capacity: approximately 5.7 quarts (with filter).
- Oil viscosity notes: 0W-20 is the standard; some regions and model variants may list 0W-20 as the preferred grade; verify with the owner's manual for your exact vehicle.
- Oil spec and grade compatibility: use oil that meets API SN or newer and ILSAC GF-6 (as applicable for your model year).
- OEM filter: use a genuine Acura/Honda filter for best performance, and replace the crush washer if applicable.
The RLX is designed with a maintenance minder system that estimates service needs based on driving conditions, not just mileage, so following the system's prompts is recommended.
Maintenance intervals and practical tips
Below are typical intervals and best practices to keep your RLX’s engine clean and compliant with warranty guidelines.
- Normal driving interval: about 7,500 miles or 12 months, whichever comes first, under standard driving conditions.
- Severe driving interval: more frequent changes may be recommended (roughly 3,750–5,000 miles or 6 months) if you operate under extreme conditions such as frequent short trips, heavy traffic, or towing.
- Practical tips: check the oil level monthly, top off with the same grade if needed, and replace the oil filter at every change.
- Reset maintenance minder after an oil change following the owner's manual steps, so future reminders reflect the new service date.
Bottom line: follow the maintenance minder guidance and use the recommended oil grade to maintain engine health and warranty compliance.
Summary
The Acura RLX generally requires synthetic 0W-20 motor oil, with a capacity of about 5.7 quarts including the filter. Use a compatible OEM or approved alternative that meets current API and ILSAC standards, and follow the maintenance minder guidance for interval scheduling. When in doubt, consult your owner’s manual or a licensed Acura technician.
Can I use 5w30 instead of 5W20 in my Acura?
Everywhere else in the world besides the US, depending on climate, Acura/Honda suggests different viscosities in our J32/J35 engines, ranging from 5w20-10w40. These engines were designed to run on 5w30. You aren't going to hurt anything. Especially if you live somewhere hot.
What kind of oil does a Acura RLX take?
The Acura RLX requires 0W-20 full synthetic motor oil. Always check your owner's manual for the specific oil type and capacity for your vehicle's model year, but for most RLX models, 0W-20 is the correct viscosity.
- Viscosity: Use a 0W-20 oil.
- Oil Type: Use full synthetic motor oil.
- API Certification: The oil should meet the American Petroleum Institute's requirements and have the API Certification Seal.
- Capacity: The oil capacity is approximately 4.2 quarts without a filter change and 4.5 quarts with a filter change for a 2016 model year, but verify this for your specific vehicle.
