Does the 2018 Acura TLX require premium gas?
Yes, the 2018 Acura TLX requires premium gasoline. This luxury sedan from Honda's premium brand is designed to run on higher-octane fuel for optimal performance and efficiency.
Acura TLX Fuel Requirements
The 2018 Acura TLX is powered by a 2.4-liter inline 4-cylinder engine or a 3.5-liter V6 engine, both of which are recommended to use premium unleaded gasoline with a minimum octane rating of 91. This is a common requirement for many luxury and performance-oriented vehicles, as the higher octane fuel helps prevent engine knocking and allows the engine to operate at its peak efficiency.
Using regular gasoline in the Acura TLX is not recommended, as it could result in reduced power, fuel economy, and engine performance. The engine is designed to take full advantage of the higher octane rating provided by premium fuel.
Why Premium Fuel is Recommended
- Engine Performance: Premium gasoline has a higher octane rating, which allows the engine to operate at higher compression ratios and temperatures without experiencing knocking or pre-ignition. This enables the engine to produce more power and torque.
- Fuel Efficiency: The higher octane rating of premium fuel can also improve fuel efficiency, as the engine can operate more efficiently with the higher-quality fuel.
- Engine Protection: Premium gasoline contains detergents and additives that can help clean and protect the engine's fuel system, reducing the risk of deposits and other issues that can occur with lower-quality fuels.
While the Acura TLX can technically run on regular gasoline, it is not recommended, as it will not provide the same level of performance, efficiency, and engine protection as premium fuel. For the best driving experience and to maintain the long-term health of the engine, Acura recommends using premium gasoline in the 2018 TLX.
