Does the 2019 Acura Ilx require premium gas?
The 2019 Acura ILX does not require premium gasoline; regular unleaded fuel (87 octane) is sufficient for normal driving. Premium fuel is optional and unlikely to yield dramatic improvements for everyday use.
For context, the ILX uses a 2.4-liter inline-4 engine, and Acura's official fuel guidance for this model year describes regular unleaded gasoline (87 octane) as the standard fuel. Higher-octane premium (91–93 octane) is not required, though some drivers may notice minor performance or smoothness differences under certain conditions. Always refer to the owner's manual or the fuel-filler-door sticker for the exact specification for your vehicle.
Fuel requirements and octane guidance
The ILX’s 2.4L engine is designed to run on regular unleaded gasoline. Acura’s documentation for the 2019 ILX lists regular 87-octane gasoline as the standard fuel, with premium gasoline as an optional choice that may offer marginal benefits in specific driving situations, but is not a necessity for daily operation.
What that means for drivers
Most owners can operação with regular gasoline without issue. If you notice knocking or pinging under heavy load or in high-temperature conditions, you can experiment with premium to see if there is any perceptible improvement, but there is no requirement to use premium to maintain performance or reliability.
Practical tips for fueling
To ensure you’re following the manufacturer’s guidance, check the owner’s manual and the fuel-filler-door decal on your specific car. Stick with 87-octane regular unleaded for daily driving, and consider premium only if you want to test for slight differences in performance under particular conditions.
Summary
In short, the 2019 ILX does not require premium gas. Regular 87-octane gasoline is suitable for routine use, and premium fuel is optional and typically provides only marginal differences in performance for most drivers. For confirmation, consult your vehicle’s manual or speak with an Acura dealer.
