Does the 2016 Acura TLX require premium gas?
Answer: It depends on the engine. The TLX's 2.4-liter four-cylinder uses regular 87-octane gasoline; the 3.5-liter V6 is designed to use premium fuel for optimal performance.
Since its 2016 refresh, Acura offered two engines in the TLX, each with its own fuel guidance. Understanding which powertrain you have is essential for choosing the right fuel, maximizing performance, and managing fuel costs. The following breakdown reflects typical guidance from Acura's manuals for that year.
Engine options and octane requirements
Before listing the octane guidelines, note that each engine has its own fuel spec. The breakdown below aligns with the 2016 TLX material provided by Acura.
- 2.4L four‑cylinder engine: Regular unleaded gasoline (87 octane) is suitable. Premium fuel is not required, though using higher-octane fuel is optional and may offer marginal benefits in certain driving conditions.
- 3.5L V6 engine: Premium gasoline (91 octane or higher) is recommended to maintain peak performance and efficiency. Using regular (87 octane) may result in reduced power or throttle response under load or hot conditions.
Bottom line: The TLX’s fuel needs are engine-specific. Identify which engine powers your car and follow the corresponding octane guidance in the owner's manual or on the fuel-cap label.
How to verify your TLX engine
To confirm which engine your TLX has, check the engine cover under the hood, review the window sticker, or consult your vehicle’s VIN documentation. In 2016, the TLX was offered with either a 2.4L four-cylinder or a 3.5L V6, and the engine type dictates the octane requirement.
Practical considerations for drivers
Beyond octane, several practical factors influence fueling decisions for the 2016 TLX. Here are key points to consider as you fuel up and drive.
- Cost versus performance: Premium gasoline is more expensive, so owners of the V6 may face higher fueling costs than those with the 2.4L engine.
- Performance perception: If you own the V6 and notice reduced acceleration or responsiveness on regular gas, switching to premium typically restores the engine’s expected performance.
- Maintenance and warranty: Follow the octane level recommended by the manual to prevent engine knock and to maintain warranty coverage.
If you’re unsure which engine powers your TLX or which octane level to use in your region, consult your Acura dealer or refer to the owner’s manual and the fuel-cap label for the precise specification.
Summary
The 2016 Acura TLX does not require premium gas across the board; it depends on the engine. The 2.4L four-cylinder uses regular 87-octane fuel, while the 3.5L V6 benefits most from premium (91 octane or higher) for best performance. If you have the V6 and cannot access premium fuel, your car will run on regular but with potential compromises in power and responsiveness. Always verify the recommended octane in your vehicle’s manual or on the fuel-cap sticker for your specific car.
