Can you use 89 octane for an Acura RDX?
No, you should not use 89 octane fuel in an Acura RDX. The Acura RDX requires premium 91 octane or higher gasoline, as recommended by the manufacturer. Using a lower octane fuel can potentially cause engine knocking and damage the vehicle's engine over time.
Detailed Explanation
The Acura RDX is a luxury crossover SUV that is designed to run on premium gasoline with a minimum octane rating of 91. This is because the RDX's turbocharged engine requires higher-octane fuel to prevent premature ignition, also known as engine knocking or pinging.
Using a lower octane fuel, such as 89 octane, can cause the fuel to ignite prematurely in the engine cylinder, leading to a knocking sound. This knocking can potentially cause damage to the engine over time, reducing its performance and lifespan. Acura specifically recommends against using anything lower than 91 octane fuel in the RDX.
Consequences of Using 89 Octane
- Engine knocking or pinging, which can damage engine components
- Reduced engine performance and fuel efficiency
- Potential long-term damage to the engine, leading to costly repairs
- Voiding the vehicle's warranty if engine damage is caused by using improper fuel
To ensure the optimal performance and longevity of your Acura RDX, it's essential to always use the recommended premium 91 octane or higher fuel, as specified by the manufacturer. Doing so will help protect your investment and keep your vehicle running at its best.
Can you run 89 octane instead of 87?
Yes, you can run 89 octane instead of 87, and it will not damage your engine. However, it is a waste of money and provides no performance benefits for most cars, as the car's computer is not designed to take advantage of the higher octane. The only time higher octane gas is necessary is if your car's manufacturer specifically recommends it for high-performance engines to prevent engine knock.

When to use higher octane gas
- For specific engines: Some high-performance engines are designed with higher compression ratios and will benefit from higher octane fuel to prevent pre-ignition or "knocking".
- When recommended by the manufacturer: Always check your owner's manual or the inside of your gas door for the manufacturer's recommendation. If your car is designed for 87 octane, you should use 87 octane.
Why using higher octane is a waste of money
- No added performance: Using a higher octane fuel than recommended will not make your car faster, more powerful, or more fuel-efficient.
- Higher cost: Higher octane gas costs more, so you are paying extra for no benefit.
- Fuel blending: In many cases, mid-grade (89 octane) gasoline is simply a blend of 87 and 91 octane fuels, so you're not getting a substantial increase in quality over what your car needs.
Can I put 89 gas in my Acura?
The answer to the question, “Does Acura require premium gas for all its models?” is no — but it's recommended that you use a higher-octane fuel in your Acura for several reasons.
Does the Acura RDX really need premium gas?
Yes, the Acura RDX recommends premium unleaded gasoline (91 octane or higher) for optimal performance, but it can run on regular gas. Using regular gas may result in reduced power, lower fuel economy, and potential engine knocking, as the engine will automatically adjust by retarding its timing.
Using premium gas (recommended)
- Ensures the turbocharged engine performs at its best.
- Helps maintain the vehicle's intended power and fuel economy.
- Prevents engine knocking or rattling.
Using regular gas
- The engine will adjust and pull timing to avoid pre-ignition.
- You may experience a noticeable decrease in power and torque.
- Your fuel economy will likely be lower.
- In the long term, it's recommended to use premium to avoid potential issues and maintain performance.
What is the lawsuit against the Acura RDX?
In the case, plaintiffs alleged that America Honda Motor Co., Inc. (“AHM”) knowingly sold its 2019-2020 Acura RDX vehicles with defective infotainment systems that behaved erratically, malfunctioned, and repeatedly froze, thereby distracting the driver and posing a safety hazard.
