Does the 2015 Acura ILX require premium gas?

Yes, the 2015 Acura ILX does require premium gasoline. This luxury compact sedan from Honda's premium brand is designed to run on higher-octane fuel for optimal performance and efficiency.


Acura ILX Fuel Recommendations


According to the owner's manual for the 2015 Acura ILX, the recommended fuel is premium unleaded gasoline with a pump octane number of 91 or higher. Acura specifically advises against using regular unleaded gasoline, as it can cause engine knocking and damage the engine over time.


The 2015 ILX is powered by a 2.4-liter four-cylinder engine that produces 201 horsepower. This engine is tuned to take advantage of the higher octane rating of premium fuel, which allows for increased compression and more efficient combustion.


Consequences of Using Regular Gasoline



  • Engine knocking or pinging noises

  • Reduced fuel economy

  • Lower performance and acceleration

  • Potential long-term engine damage


While the 2015 Acura ILX can technically run on regular 87-octane gasoline, it is not recommended by the manufacturer. Using the wrong fuel can lead to a variety of issues, from annoying engine noises to serious mechanical problems down the road. For the best performance, fuel efficiency, and longevity of the vehicle, premium gasoline is required.p>

Fuel Economy and Costs


The 2015 Acura ILX with the 2.4-liter engine is rated by the EPA to achieve 25 mpg in the city and 36 mpg on the highway when using premium fuel. While premium gasoline typically costs more per gallon than regular, the improved fuel efficiency of the ILX can help offset the higher fuel costs.


Overall, the 2015 Acura ILX is designed to run on premium gasoline, and using anything less can have negative consequences for the vehicle's performance and long-term health. Drivers should heed the manufacturer's recommendations to ensure the best driving experience and protect their investment.
