How much does it take to fill up an Acura RDX?

The cost to fill up an Acura RDX can vary depending on factors such as the current price of gasoline, the size of the vehicle's fuel tank, and the driver's driving habits. On average, it costs between $40 to $60 to completely fill up the gas tank of an Acura RDX.


Understanding the Acura RDX's Fuel Tank Capacity


The Acura RDX has a fuel tank capacity of 16.1 gallons. This means that the vehicle can hold up to 16.1 gallons of gasoline when the tank is completely empty. The actual amount of fuel needed to fill up the tank will depend on how much gas is already in the tank before refueling.


Calculating the Cost to Fill Up


To calculate the cost to fill up an Acura RDX, you'll need to know the current price of gasoline in your area. As of Thursday, February 27, 2025, the national average price of regular gasoline in the United States is $3.75 per gallon.


Using this average price, the cost to completely fill up the 16.1-gallon fuel tank of an Acura RDX would be:



  • 16.1 gallons x $3.75 per gallon = $60.38


However, it's important to note that the actual cost can vary depending on your local gas prices, which may be higher or lower than the national average. Additionally, your driving habits and the vehicle's fuel efficiency will also impact how often you need to refill the tank and the total cost of fuel over time.


Tips for Maximizing Fuel Efficiency


To help reduce the frequency and cost of filling up your Acura RDX, consider the following tips to improve fuel efficiency:



  • Maintain proper tire pressure

  • Avoid aggressive acceleration and braking

  • Remove unnecessary weight from the vehicle

  • Use the recommended grade of fuel

  • Keep the vehicle well-maintained, including regular oil changes


By following these tips, you can help maximize the fuel efficiency of your Acura RDX and potentially reduce the overall cost of refueling the vehicle.
