How can I optimize my Kia Soul's fuel efficiency?

I've noticed that my Kia Soul's gas mileage isn't as good as it used to be. Are there any steps I can take to improve its fuel efficiency?

First, make sure you are keeping up with regular maintenance such as oil changes and tire rotations. This will ensure that your car is running efficiently and not working harder than it needs to.

Consider switching to a synthetic motor oil, as it can reduce friction and improve fuel economy.

Check your tire pressure regularly and make sure it is at the recommended level. Under-inflated tires can decrease fuel efficiency.

Avoid carrying excess weight in your car, as it can put extra strain on the engine and decrease fuel efficiency.
