Can I put regular gas in an Acura TLX?

The short answer is no, you should not put regular gas in an Acura TLX. The Acura TLX is designed to run on premium gasoline, and using regular gas can potentially cause damage to the engine and reduce the vehicle's performance.


Understanding the Acura TLX's Fuel Requirements


The Acura TLX is a luxury sedan that is powered by a turbocharged or naturally aspirated engine, depending on the model. These engines are designed to operate at higher compression ratios, which require the use of premium gasoline (91 octane or higher) to prevent knocking or pre-ignition. Using regular gasoline (87 octane) in an Acura TLX can lead to a decrease in fuel efficiency, reduced power, and potentially cause long-term damage to the engine.


Consequences of Using Regular Gas in an Acura TLX


Using regular gas in an Acura TLX can have several negative consequences, including:



  • Reduced Performance: The engine in the Acura TLX is designed to operate at its best with premium fuel. Using regular gas can result in a noticeable decrease in acceleration, power, and overall driving performance.

  • Decreased Fuel Efficiency: Premium gasoline has a higher octane rating, which allows the engine to run more efficiently. Using regular gas can lead to a decrease in fuel economy, resulting in higher fuel costs over time.

  • Engine Damage: The higher compression ratio of the Acura TLX's engine requires the use of premium fuel to prevent knocking or pre-ignition, which can cause significant damage to the engine over time.


It's important to always refer to the owner's manual for your specific Acura TLX model to ensure you are using the recommended fuel type. Failure to do so can void the vehicle's warranty and lead to costly repairs down the line.
