Does the Acura TSX only take premium gas?
Yes, the Acura TSX is designed to run on premium gasoline. The Acura TSX is a luxury sedan that requires higher-octane fuel to operate at its optimal performance and efficiency levels.
Acura TSX Fuel Requirements
The Acura TSX is powered by a 2.4-liter four-cylinder engine that is tuned to take advantage of the higher octane rating of premium gasoline. According to the owner's manual, the recommended fuel for the Acura TSX is 91 octane or higher. 1 Using a lower-octane regular gasoline could result in reduced engine performance, decreased fuel economy, and potential engine damage over time.
The higher compression ratio of the Acura TSX engine requires the increased combustion resistance of premium fuel to prevent knocking and pre-ignition. 2 This helps maintain the engine's optimal power output and efficiency. While the Acura TSX can technically run on regular 87 octane gasoline, it is not recommended by the manufacturer.
Consequences of Using Regular Gasoline
- Reduced engine power and acceleration
- Decreased fuel economy
- Potential for engine knocking or pinging
- Increased risk of long-term engine damage
Using the recommended premium fuel ensures the Acura TSX engine operates as designed, providing the best balance of performance, efficiency, and longevity. While premium gas may cost more per gallon, the benefits typically outweigh the additional fuel cost for Acura TSX owners.
Conclusion
In summary, the Acura TSX is engineered to run on premium 91 octane or higher gasoline. Using a lower-octane regular fuel can compromise the engine's performance, fuel economy, and long-term reliability. For the best driving experience and to protect the investment in an Acura TSX, premium fuel is the recommended choice.
