How can I improve fuel efficiency in my Kia ProCeed?

I've been noticing that my Kia ProCeed's fuel efficiency has been slowly decreasing. I'm wondering if there's anything I can do to improve it and save some money on gas. Are there any tips or tricks I should know about?

Firstly, make sure to keep up with regular maintenance checks and tune-ups for your Kia ProCeed. This will ensure that all components, such as the air filter, spark plugs, and tires, are in good condition and working efficiently.

In addition, try to drive smoothly and avoid sudden accelerations and harsh braking. This can significantly improve fuel efficiency by reducing fuel consumption.

Consider using a fuel additive or cleaner to remove any deposits that may be hindering your Kia ProCeed's fuel efficiency. Also, check your tire pressure regularly as under-inflated tires can decrease fuel efficiency.
