I have noticed that the fuel economy on my Nissan Qashqai has been decreasing over the past few months. I used to get much better mileage when I first bought the car. What could be causing this decrease and how can I improve the fuel efficiency?
ReplyFirst of all, make sure you are regularly maintaining your car by getting oil changes and tune-ups as recommended by the manufacturer. Old oil and dirty filters can significantly affect your fuel economy. Additionally, check your tire pressure regularly and keep them at the recommended level. Under-inflated tires can decrease your mileage. It might also be worth considering switching to a higher octane fuel for improved efficiency.
