Do Acura vehicles require premium gas? For most Acura models, premium gasoline is recommended rather than strictly required, but choosing the right fuel makes a difference in how your vehicle performs. At Acura of Sherman Oaks, we want you to know exactly what to put in your tank, whether regular gas is safe to use, and why octane matters for your engine.
Which Acura Models Need Premium Gas?
Premium unleaded gasoline with a 91-octane rating is the recommended fuel for most gasoline-powered Acura models. This includes the Acura MDX, Acura RDX, and Acura Integra. The high-performance Acura Integra Type S has a higher recommendation of 93 octane.
So, can you use regular 87-octane gasoline instead? In models that permit it, yes. However, you may notice a difference in acceleration and overall engine performance.
The important distinction is between recommended and required fuel. A recommendation identifies the octane rating that delivers the intended performance, whereas a requirement establishes the minimum acceptable rating. Always check your owner's manual before switching to a lower octane.
What Happens If You Put Regular Gas in an Acura?
The biggest difference between regular and premium gasoline is octane. Higher-octane fuel resists engine knock, which occurs when the air-fuel mixture combusts at the wrong time. Many Acura engines use turbocharging or relatively high compression ratios to generate power. These designs benefit from premium gasoline because it allows the engine to operate closer to its intended ignition timing.
When you use lower-octane fuel, the engine's computer can adjust ignition timing to reduce knocking. That protection can come at the expense of horsepower and responsiveness, particularly during hard acceleration.
If you accidentally fill up with 87 octane, there's generally no need to drain the tank if your model permits regular gasoline. Avoid aggressive acceleration and return to premium fuel at your next fill-up. Never use gasoline below the minimum octane specified in your owner's manual.
