What happens if I accidentally put regular gas in my Acura?

If you accidentally put regular gasoline in your Acura, it's not the end of the world, but it's important to address the issue as soon as possible. Acuras are designed to run on premium fuel, and using regular gas can have some negative consequences for your vehicle.


Potential Consequences of Using Regular Gas in an Acura


When you put regular gas in an Acura, the engine may experience a decrease in performance, reduced fuel efficiency, and potentially even long-term damage. This is because Acura engines are designed to operate at higher compression ratios, which require the higher octane rating of premium fuel to prevent knocking or pinging.



  • Decreased Performance: The lower octane rating of regular gas can cause the engine to knock or ping, which can lead to a loss of power and acceleration.

  • Reduced Fuel Efficiency: Using regular gas in an Acura can result in a decrease in fuel efficiency, meaning you'll get fewer miles per gallon.

  • Potential Engine Damage: In the long run, consistently using regular gas in an Acura can lead to increased wear and tear on the engine, potentially causing more serious problems down the line.


It's important to note that the severity of these consequences can vary depending on factors such as the frequency and duration of using regular gas, the specific Acura model, and the overall condition of the engine.


What to Do If You Accidentally Put Regular Gas in Your Acura


If you realize you've put regular gas in your Acura, the best course of action is to take the following steps:



  • Don't Start the Engine: If you've just filled up with regular gas, don't start the engine. This can help prevent any potential damage to the engine.

  • Drain the Fuel Tank: You'll need to have the regular gas drained from the fuel tank and replaced with the recommended premium fuel. This is best done by a professional mechanic.

  • Refill with Premium Fuel: Once the regular gas has been removed, fill up your Acura with the recommended premium fuel. This will help restore the engine's performance and efficiency.

  • Monitor the Engine: After refilling with premium fuel, keep an eye on your Acura's performance and any warning lights or indicators. If you notice any issues, have your vehicle checked by a qualified mechanic.


By taking these steps, you can minimize the potential damage to your Acura and ensure that it continues to perform at its best.
