Data verified by Nick Marchenko, PhD
Maintaining your Acura ILX is essential for optimal performance and longevity. The 2013–2022 Acura ILX offers five engine options, including the K24Z7 (2.4L I-4) and R20A5 (2.0L I-4), each requiring specific oil capacities and viscosities. For instance, the K24Z7 engine, available in 2013 and 2014, has an oil capacity of 4.4 quarts with a recommended viscosity of 0W-20. In contrast, the K25V7 engine, found in models from 2016 to 2022, requires 4.6 quarts of the same viscosity.
Additionally, the R20A5 engine, which powers the 2013–2015 models, has a smaller oil capacity of 3.9 quarts. It's also crucial to monitor coolant levels, with the K24Z7 requiring between 5.6 to 5.8 quarts, while the K25V7 engines need up to 6.9 quarts. Regular oil changes not only ensure your engine runs smoothly but also help in maintaining the overall health of your vehicle.

What is the coolant capacity of the Acura ILX?
The coolant capacity for the Acura ILX varies by engine; the K24Z7 requires between 5.6 to 5.8 quarts, while the K25V7 can require up to 6.9 quarts.
Does the Acura ILX need synthetic oil?
While synthetic oil is not strictly required, it is highly recommended for the Acura ILX as it provides better protection and performance, especially in extreme temperatures.
What happens if I use the wrong oil viscosity in my Acura ILX?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potentially overheating, which can severely damage the engine.
What is an oil life monitor and how does it work?
An oil life monitor is a system that calculates the remaining life of your engine oil based on driving conditions and habits, alerting you when it's time for an oil change.
Can I mix synthetic and conventional oil?
While it's technically possible to mix synthetic and conventional oils, it is not recommended as it can reduce the benefits of synthetic oil and may lead to performance issues.
How do I know if my Acura ILX has an oil leak?
Signs of an oil leak include oil spots under the vehicle, a drop in oil levels on the dipstick, or a burning oil smell while driving.
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 damage 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 warm but not hot, as this allows for a more accurate reading on the dipstick.
What is the difference between an oil change and a flush?
An oil change involves draining the old oil and replacing it with new oil, while an oil flush uses a cleaning solution to remove sludge and deposits before adding new oil.
