Data verified by Nick Marchenko, PhD
Maintaining proper oil levels and quality is crucial for the performance and longevity of your 2014–2019 Acura RLX. This luxury sedan comes equipped with two engine options: the J35Y4 3.5L V-6 engine, which has an oil capacity of 4.2 quarts for models from 2014 to 2017, and a slightly larger 4.5 quarts for the 2018 and 2019 models. Both engines require a viscosity of 0W-20, ensuring optimal performance in various driving conditions.
In addition to oil maintenance, it's important to keep an eye on the coolant levels, which are set at 8.5 quarts for both engine configurations. Regular oil changes, in accordance with the manufacturer's recommendations, will help maintain engine health and efficiency, allowing your Acura RLX to perform at its best.

What type of oil does the Acura RLX use?
The Acura RLX uses 0W-20 engine oil across all its engine variants. Full synthetic oil meeting API/ILSAC specifications is strongly recommended for optimal engine protection and performance.
What is the coolant capacity of the Acura RLX?
The coolant capacity for the Acura RLX varies by engine: J35Y4: 8.5 qt; J35Y4: 8.5 qt. Use the coolant specification listed in the owner's manual for your engine variant.
What type of oil does the Acura RLX use?
The Acura RLX uses 0W-20 viscosity oil for both of its engine options.
How many quarts of oil does the Acura RLX take?
The 2014–2017 Acura RLX with the J35Y4 engine has an oil capacity of 4.2 quarts, while the 2018–2019 models require 4.5 quarts.
How often should I change oil in a Acura RLX?
It's recommended to change the oil in your Acura RLX every 7,500 miles or 12 months, whichever comes first, but always refer to your owner's manual for specific guidance.
What is the coolant capacity of the Acura RLX?
The coolant capacity for both engine options in the Acura RLX is 8.5 quarts.
Does the Acura RLX need synthetic oil?
While synthetic oil is not mandatory, it is highly recommended for the Acura RLX as it provides better engine protection and performance.
What happens if I use the wrong oil viscosity in my Acura RLX?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating, which can severely damage the engine.
What is an oil life monitor and how does it work?
An oil life monitor tracks the engine's operating conditions and driving habits to determine when an oil change is necessary, providing a more accurate interval than just mileage.
Can I mix synthetic and conventional oil?
While it's technically possible to mix synthetic and conventional oils, it's not recommended as it can reduce the effectiveness of the synthetic oil.
How do I know if my Acura RLX has an oil leak?
Signs of an oil leak include oil spots under the vehicle, a burning oil smell, or a drop in oil levels without any recent oil change.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn engine components, such as piston rings or valve seals, and can lead to serious engine issues if not addressed.
Should I check my oil when the engine is hot or cold?
It's best to check your oil when the engine is cold, as this provides a more accurate reading of the oil level.
What is the difference between an oil change and a flush?
An oil change involves draining old oil and replacing it with new oil, while an oil flush cleans the engine by removing sludge and contaminants before adding new oil.
