One way to improve gas mileage is to regularly maintain your vehicle. Make sure to get your oil changed on time and check your tire pressure regularly. This can help improve fuel efficiency.

Consider using a fuel additive or high-quality gasoline to improve gas mileage. These can help clean your engine and improve its performance.

Avoid excessive idling and try to combine trips when running errands. This can help save gas and improve your overall gas mileage.
