Opting for a used Hyundai Elantra Eco is the best way to capitalize on the model’s fuel efficiency, while the Elantra Sport is the least fuel-efficient model in the 2020 lineup. That being said, there are some ways that you can save on fuel costs for your Elantra. Let’s take a closer look.
  • Keep up with maintenance. Letting small problems develop into big problems can, in certain cases, affect the model’s fuel efficiency over time. 
  • Drive carefully. Avoiding harsh acceleration and riding the brake can help to keep your fuel consumption both steady and low. 
  • Avoid idling, especially in cold weather. Idling your Hyundai’s engine leads to wasting fuel. Avoid letting your engine run, even if you’re just trying to warm up your car, if you want to conserve fuel.
