How to improve the fuel efficiency in my Kia ProCeed?

I have noticed that my Kia ProCeed's fuel efficiency has been declining lately. What steps can I take to improve it?

You can start by regularly checking and replacing your air filter. A clogged air filter can reduce fuel efficiency by up to 10%.

Another tip is to ensure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency by up to 3%.

Consider using a fuel injector cleaner to improve the performance of your engine and increase fuel efficiency.

Be conscious of your driving habits. Avoid aggressive acceleration and braking, which can waste fuel.
