Does the Acura TLX 2.4 require premium gas?
Yes, the Acura TLX 2.4-liter engine requires premium gasoline. This is a common recommendation for many luxury and performance-oriented vehicles to ensure optimal engine performance and fuel efficiency.
Detailed Explanation
The Acura TLX is a midsize luxury sedan offered with two engine options: a 2.4-liter inline-four and a 3.5-liter V6. The 2.4-liter engine, which is the base engine, is specifically designed to run on premium unleaded gasoline with a minimum octane rating of 91.
Using regular gasoline in an engine that requires premium can lead to several issues, including:
- Reduced engine power and performance
- Lower fuel efficiency
- Increased risk of engine knocking or pinging
- Potential long-term damage to the engine components
Acura, like many other automakers, recommends premium fuel for their engines to ensure optimal performance, efficiency, and longevity. While it is possible to use regular gasoline in the Acura TLX 2.4, it is not advisable, as it can negatively impact the engine's operation and potentially void the vehicle's warranty.
Fuel Octane Ratings Explained
Gasoline octane ratings refer to the fuel's resistance to premature ignition, also known as "knocking" or "pinging." Higher-octane fuels, such as premium (91-93 octane), are less prone to this issue, making them better suited for high-performance engines that operate under higher compression and temperatures.
The Acura TLX 2.4-liter engine is designed to take advantage of the higher octane rating of premium fuel, allowing for increased power output, improved fuel efficiency, and better engine protection. Using a lower-octane fuel can cause the engine to knock, which can lead to long-term damage if not addressed.
In summary, the Acura TLX 2.4-liter engine requires premium gasoline (91 octane or higher) to function as intended by the manufacturer. Using regular gasoline may result in reduced performance, fuel economy, and potential engine damage, and is not recommended for this vehicle.
Can you mix 87 and 91 gas?
Typically you'll want to stick to the gas that is recommended for your own vehicle, but you may be wondering what happens if you mix premium and regular gas? It depends on the situation, but mixing regular and premium gas is typically not detrimental to newer engines.
Does TLX require premium gas?
According to Acura, the Acura NSX requires premium gas. For models like the RDX, MDX, TLX, RLX, and ILX, premium gas is recommended.
Can I put regular gas in my Acura TLX?
We contacted Acura and Nissan, asking why both automakers recommend using premium gas. An Acura spokesperson referred us to the TLX's owner's manual, which states, “Use of lower-octane gasoline can cause occasional metallic knocking noise in the engine and will result in decreased engine performance.”
What to do if you put 87 instead of 91?
For some car models, higher octane fuel is recommended instead of required. If that's you, the lower stuff should be sufficient enough to not cause problems. But if you hear knocking and pinging noises, or you're not getting the mileage you should, switch to higher octane gas at your next fill up.
Will regular gas ruin my premium car?
However, remember this: when a premium fuel engine runs on regular fuel, there's a risk of combustion of the fuel mix before the spark plug even lights up. This causes a phenomenon called knocking, which is likely to damage the engine.
What happens if I don't use premium gas in my Acura?
When you fill your Acura's fuel tank with a lower octane level than is recommended, you'll experience pre-ignition (also known as engine knocking). Pre-ignition negatively affects your fuel economy and can damage your pistons or cylinder walls over time.
Do all Acura models require premium gas?
According to Acura, premium gas is required for the Acura NSX, and it's recommended for the MDX, RDX, TLX, RLX, and ILX. The answer to the question, “Do all Acuras require premium gas?” is no — but it's recommended that you use a higher-octane fuel in your Acura for several reasons.
Do Acuras hold their value?
Acura vehicles are renowned for retaining their value, and experiencing less depreciation compared to other brands. Discover what makes Acura vehicles a smart investment below.
Is it worth putting 91 instead of 87?
Premium gas is also often called high-octane gas thanks to its octane rating of 91 to 94. Regular gas typically has an 87 rating, while the 88-90 range is considered midgrade. Premium gas drives performance in specific engines, but the idea that it's more fuel efficient is a myth.
What happens if I accidentally put regular gas in my Acura?
If you put lower-octane fuel into your high-octane vehicle, whether by mistake or to save money on gas, you'll probably notice the effects right away: things like poor fuel economy, reduced acceleration, and spark knock, which sounds like a high-pitched pinging or rattling noise.
