Low Fuel Efficiency in Kia Ceed

I recently bought a Kia Ceed and I noticed that its fuel efficiency is not as good as advertised. What could be causing this issue?

I suggest checking your tire pressure regularly, as under-inflated tires can greatly affect fuel efficiency.

Another factor to consider is your driving style. Avoid rapid acceleration and braking, as it can significantly increase fuel consumption.

Make sure to maintain your car's engine regularly, as a dirty air filter or clogged fuel injectors can also contribute to poor fuel efficiency.
