Premium unleaded 91 octane fuel is required for the Acura NSX and recommended for the Acura ILX, Acura TLX, Acura RLX, Acura MDX, Acura RDX. Don’t be scared, though — there’s a reason that your Acura should use premium gas.

Why is Premium Gas Recommended for Acura Models?

Asking whether your Acura needs premium gas is a little like asking if your body needs healthy food — you can get along with something less, but why wouldn’t you treat your body to the best there is?

Your Acura ILX, TLX, RLX, MDX, or RDX will run fine on regular gas, but using the recommended premium unleaded 91 octane fuel will improve performance and boost longevity, something that should give you confidence between Naperville and Plainfield as well as on the long haul. For a high-performance vehicle like the Acura NSX, premium fuel is downright necessary to keep its exhilarating 573-hp powertrain working at full strength.

Octane Ratings and Your Acura

A fuel’s octane rating measures its stability during combustion. A high octane rating is more resistant to “knocking” or “pinging,” so the air/fuel mixture is less likely to denotate prematurely. In the U.S, octane ratings usually break down as:

  • 87 for Regular
  • 88 – 90 for Midrange
  • 91 – 94 for Premium

Acura models tend to be designed for high performance, often fitting turbochargers or superchargers with that end in mind. Their engines use a higher compression ratio than average, which means that higher-octane fuel is recommended to prevent pre-detonation. You’ll likely notice the difference in terms of both performance and efficiency, too.
