Can Acura ILX run on regular gas?
The Acura ILX can run on regular gasoline, but the exact octane you should use depends on your engine variant and model year. In practice, many ILX models tolerate regular 87-octane fuel, while some configurations benefit from higher-octane premium fuel for optimal performance. Always verify with your specific vehicle’s manual and labels.
Understanding the octane needs of the ILX
Octane rating measures a fuel’s resistance to pre-ignition, which matters for engine performance and longevity. The ILX, produced in different trims and years, has guidance that varies by engine type. The safest approach is to confirm the requirement for your exact car, but there is a general pattern buyers should know when considering regular versus premium gasoline.
Engine variants and general guidance
The ILX was offered with more than one engine during its production run. While some owners report that regular gasoline is acceptable, other variants with higher-compression designs are better served by premium gasoline to preserve performance and fuel efficiency. Because the recommendation can differ by model year and engine, you should check the owner’s manual and the fuel-filler label on your vehicle for the definitive answer.
To help you determine what to do next, here are the practical steps you can take regardless of your exact model:
Before you read the list, note that you should always look up the octane guidance for your specific car to avoid misinterpretation.
- Check the owner’s manual for the official octane recommendation (often stated as regular 87 octane or premium 91+ octane for certain engines).
- Inspect the fuel-filler door label, which typically repeats the octane guidance or shows the acceptable fuel types.
- Consult your local Acura dealer or service department if you’re unsure about your particular engine and model year.
In summary, the exact octane requirement is not identical across all ILX versions; verify with official documentation for your car to ensure you choose the right fuel for your engine and driving conditions.
What happens if you use regular versus premium
Choosing the right octane can affect performance and efficiency. Using the incorrect octane can lead to reduced power, knocking, or less-than-optimal fuel economy, especially under heavy load or hot conditions. Premium fuel might provide smoother operation and the highest possible performance on engines designed to benefit from higher compression, whereas regular fuel is typically sufficient for many ILX configurations used in everyday driving.
Below are common scenarios to watch for as you decide which fuel to use.
- Engine knocking or pinging under acceleration or climbs, particularly under load or hot weather.
- Noticeable drop in throttle response or performance when using regular fuel in engines that benefit from higher-octane fuel.
- Difficulty achieving expected horsepower or peak performance during spirited driving.
If you observe any of these symptoms, consider testing premium gasoline in your next fill-up to see if performance improves, and consult your dealer for an engine health check.
Summary
In short, the Acura ILX can operate on regular gasoline, but octane needs vary by engine and model year. Always verify with the owner’s manual and the fuel door label for your specific car. If you drive aggressively, tow, or operate in hot climates, premium fuel may help preserve performance and efficiency. When in doubt, consult an Acura dealer to confirm the best fuel choice for your ILX.

According to Acura, premium gas is only required for the Acura NSX and is recommended for the MDX, RDX, TLX, RLX, and ILX.
What happens if I put 87 in my Acura?
Possible Engine Knocking: Lower-octane fuel can cause engine knocking (a knocking sound), which can be damaging over time. Lower Fuel Efficiency: Regular gas may not burn as efficiently as premium fuel, which can cause lower miles per gallon (MPG).
Can you put regular gas in an Acura ilx?
According to Acura, premium gas is required for the Acura NSX, and it's recommended for the MDX, RDX, TLX, RLX, and ILX. The answer to the question, “Do all Acuras require premium gas?” is no — but it's recommended that you use a higher-octane fuel in your Acura for several reasons.
