How to improve gas mileage on my Nissan Micra?

I've noticed that my Nissan Micra isn't getting as many miles per gallon as it used to. What can I do to improve its gas mileage?

Firstly, make sure your tires are properly inflated. Underinflated tires can decrease gas mileage by up to 3%. Additionally, avoid speeding and quick accelerations, as these can also decrease gas mileage.

Regular maintenance is key for improving gas mileage. Make sure to get your oil changed, air filter replaced, and spark plugs checked according to your vehicle's maintenance schedule.

Consider switching to a higher octane gas if you're using regular or mid-grade. While more expensive, it can improve your gas mileage and overall performance.
