What Type of Gas Does the Acura ADX Need?
October 14 2025 - CardinaleWay Acura Las Vegas

The ADX runs best on premium unleaded gasoline (91 octane) — the same recommendation across Acura’s turbocharged lineup.

You can safely use regular fuel, but doing so can slightly reduce performance and efficiency. In the long run, using premium helps the engine deliver full horsepower, smoother acceleration, and better mileage — especially important when merging onto I-15 or making quick moves in city traffic.

In short:

  • Recommended: Premium (91 octane)
  • Acceptable: Regular (87 octane, with minor performance trade-offs)
  •  

For Las Vegas drivers, where freeway speeds, elevation changes, and heat can all challenge an engine, premium fuel helps maintain consistent power and efficiency year-round.
