What kind of oil does a 2014 Acura RLX use?
The 2014 Acura RLX uses 0W-20 synthetic engine oil.
Beyond the grade, the RLX owner’s manual specifies that the oil should meet ILSAC GF-5 (API SN or newer) standards. If 0W-20 is unavailable, a temporary use of 5W-20 is allowed, but you should revert to 0W-20 as soon as possible. Always check the manual or with a dealer for climate-specific recommendations.
Oil grade and compatibility
The following notes summarize the key specifications to ensure proper lubrication and performance.
- Oil grade/viscosity: 0W-20 synthetic motor oil. The oil should meet ILSAC GF-5 and API SN (or newer) standards.
- Alternative when needed: 5W-20 can be used temporarily if 0W-20 is not available; switch back to 0W-20 as soon as possible.
- Quality standards: Use a reputable full-synthetic brand or Honda/Acura-approved oil to ensure compatibility with the RLX’s engine and emissions systems.
Adhering to these specifications helps maintain lubrication quality, fuel efficiency, and emissions performance for the RLX.
Oil capacity and maintenance interval
These details relate to how much oil the engine holds and when to change it, as guided by the vehicle’s maintenance system and manual.
- Oil capacity: Approximately 5 quarts with filter; exact capacity can depend on the specific engine variant and model year, so confirm with the owner's manual or service department.
- Change interval: Rely on the vehicle’s maintenance minder. Normal conditions typically call for oil changes at longer intervals (often around 7,500 miles or more), while severe service may require more frequent changes (potentially around 3,750 miles or as indicated by the minder).
- Service considerations: Use synthetic oil and a fresh filter for each change to maximize engine protection and longevity.
Following the recommended oil type and maintenance intervals helps preserve engine performance, efficiency, and warranty coverage.
Summary
The 2014 Acura RLX is designed to run on 0W-20 synthetic oil that meets ILSAC GF-5/API SN or newer standards. If 0W-20 is temporarily unavailable, 5W-20 may be used briefly, with a return to 0W-20 as soon as possible. Expect an oil capacity near 5 quarts with filter, and rely on the maintenance minder to determine when to change the oil—typically around 7,500 miles under normal conditions, with more frequent changes under severe driving. Always consult the owner’s manual or a certified Acura technician for model-specific guidance and climate considerations.
