2018 Acura MDX Owners Manual - Refueling



Refueling

Use the proper fuel and refueling procedure to ensure the best performance and safety of your vehicle.

Fuel Information

Use of unleaded premium gasoline of 91 octane or higher is recommended.

  • Acura recommends TOP TIER Detergent Gasoline where available.
  • Do NOT use gasoline containing more than 15% ethanol.
  • Do NOT use gasoline containing methanol.
  • Do NOT use gasoline containing MMT.
NOTICE

We recommend quality gasoline containing detergent additives that help prevent fuel system and engine deposits. In addition, in order to maintain good performance, fuel economy, and emissions control, we strongly recommend the use of gasoline that does NOT contain harmful manganese-based fuel additives such as MMT, if such gasoline is available.

How to Refuel

Your fuel tank is not equipped with a fuel fill cap. You can insert the filler nozzle directly into the filler pipe. The tank seals itself again when you pull out the filler nozzle.

  1. The fuel fill door is located at the left rear of the vehicle. Park next to the service pump that is most accessible, and turn off the engine.
  2. Press the fuel fill door release button. The fuel fill door opens.
  3. Place the end of the filler nozzle on the lower part of the filler opening, then insert it slowly and fully. Make sure that the end of the filler nozzle goes down along with the filler pipe.
  4. After filling, wait about 5 seconds before removing the filler nozzle. Close the fuel fill door by hand.
WARNING

Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel.

  • Stop the engine, and keep heat, sparks, and flame away.
  • Handle fuel only outdoors.
  • Wipe up spills immediately.

Refueling from a Portable Fuel Container

When you refuel from a portable fuel container, use the funnel provided with your vehicle.

  1. Turn off the engine.
  2. Press the fuel fill door release button. The fuel fill door opens.
  3. Take the funnel out of its clip in the cargo area (see "Using the Spare Tire*").
  4. Remove the funnel from the case.
  5. Place the end of the funnel on the lower part of filler opening, then insert it slowly and completely. Make sure that the end of the funnel goes down along with the filler pipe.
  6. Fill the tank with fuel from the portable fuel container. Pour fuel carefully so you do not spill any.
  7. Remove the funnel from the filler neck. Wipe up any fuel from the funnel before storing it.
  8. Shut the fuel fill door by hand.
NOTICE

Do not insert the nozzle of a portable fuel container or any funnel other than the one provided with your vehicle. Doing so can damage the fuel system.

Do not try to pry open or push open the sealed fuel tank with foreign objects. This can damage the fuel system and its seal.

Improving Fuel Economy and Reducing CO2 Emissions

Achieving fuel economy and reducing CO2 emissions is dependent on several factors, including driving conditions, load weight, idling time, driving habits, and vehicle condition. Depending on these and other factors, you may not achieve the rated fuel economy of this vehicle.
