Does Acura need premium gas?

The short answer is that most Acura models recommend the use of premium gasoline, but it is not always strictly required. The specific fuel requirements can vary depending on the Acura model and engine type.


Acura's Fuel Recommendations


Acura, a luxury vehicle brand owned by Honda, generally recommends the use of premium unleaded gasoline (91 octane or higher) for its vehicles. This is because Acura engines are designed to take advantage of the higher octane rating of premium fuel, which can help improve performance, fuel efficiency, and engine longevity.


However, it's important to note that Acura's fuel recommendations are not set in stone. Some Acura models, particularly those with smaller displacement engines, may be able to run on regular unleaded gasoline (87 octane) without any significant issues. The owner's manual for each Acura vehicle will provide the specific fuel requirements.


Consequences of Using Regular Fuel in an Acura


While Acura recommends premium fuel, using regular gasoline in an Acura vehicle that is designed for premium fuel is generally not recommended. Here are some potential consequences:



  • Reduced performance: The engine may not be able to produce its full power and acceleration capabilities when using regular fuel.

  • Lower fuel efficiency: The engine may not be able to operate as efficiently, leading to decreased fuel economy.

  • Increased risk of engine knocking or pinging: The lower octane rating of regular fuel can cause the engine to experience knocking or pinging, which can potentially lead to engine damage over time.

  • Voided warranty: In some cases, using regular fuel in an Acura that requires premium may void the vehicle's warranty, as it could be considered a form of owner neglect or misuse.


It's important to always refer to the owner's manual and follow Acura's recommended fuel requirements to ensure the best performance, fuel efficiency, and long-term engine health for your Acura vehicle.

What happens if I use 87 instead of 91?


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.



Does the Acura MDX really need premium gas?


The Acura MDX may be a premium SUV, but does the Acura MDX require premium gas? The answer is no, but it is recommended by the manufacturer. The only vehicle in the Acura lineup that absolutely must use premium gas is the Acura NSX sports car, due to its turbocharged engine.



Can Acura run on regular gas?


The Acura MDX, RDX, TLX, RLX, and ILX all run more efficiently on premium gas, but you can use regular gas if you need to.



What happens if I don't use premium gas in my Acura RDX?


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.



Can I mix regular and premium gas?


There's nothing wrong with mixing premium and regular gas in the same tank. In fact, this is how midgrade gas is formulated at the station. Rather than drawing from a separate storage tank for each octane rating, gas pumps actively mix high-octane fuel with lower-octane fuel to create midgrade gas.



Can you put 87 gas in an Acura RDX?


If you want to experience the full performance potential of your new Acura, it's best to opt for premium gas. Your luxury vehicle is still able to run on lower-octane or regular gas, but with this type of fuel, you won't be able to see all that it can do.



What happens if you accidentally put regular gas instead of premium in an Acura?


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.”

While modern vehicles, Acuras included, are equipped with knock sensors to prevent pre-ignition, using premium gas becomes essential for unlocking the full performance potential.
