What kind of gas does a 2016 Acura ILX take?
The 2016 Acura ILX is designed to run on premium unleaded gasoline with an octane rating of 91 or higher. Regular 87 octane can be used in emergencies, but expect reduced performance and fuel efficiency if you regularly rely on it.
Fuel requirements for the 2016 ILX
Here are the essentials you should know about octane needs, fuel economy, and what the owner’s manual advises for this model year. The information helps ensure you get the best performance and avoid potential engine knock.
- Premium unleaded gasoline with an octane rating of 91 or higher is recommended for best performance and efficiency.
- Regular unleaded gasoline (87 octane) can be used in emergencies, but you may experience reduced power, slower acceleration, and lower fuel economy.
- Always verify the exact octane recommendation on the door jamb sticker or in the owner's manual for your specific trim and market, as formulations can vary by region.
In practical terms, sticking with premium fuel provides the best balance of performance and efficiency for the ILX. Use regular only when necessary and if you notice changes in performance, switch back when possible.
Understanding octane and engine response
How octane affects performance
Octane measures a fuel's resistance to knocking. Higher-octane fuels resist pre-ignition and allow the engine to run with the timing and compression the manufacturer designed. The ILX's engine management is tuned for premium fuel, so 91+ octane supports optimal power and smooth operation.
What to do if you must use lower-octane fuel
If you temporarily fuel with 87 octane, you may notice reduced throttle response and slightly slower acceleration as the ECU adjusts to prevent knock. If you can, refill with premium as soon as possible to restore optimum performance.
Summary
For the 2016 Acura ILX, premium unleaded gasoline with an octane rating of 91 or higher is the recommended fuel. Regular 87 octane is allowed in emergencies but can degrade performance and efficiency. Always follow the owner's manual or door jamb sticker for your specific trim and region.
