How can I increase the fuel efficiency of my Ford Mondeo?

I've been noticing that my Ford Mondeo has been using up more gas than usual. What are some tips or techniques I can implement to improve its fuel efficiency?

One simple way to improve fuel efficiency is to regularly maintain your car and ensure that all filters and fluids are clean and up to date. Additionally, try to avoid heavy acceleration and braking, as these can contribute to decreased fuel efficiency.

Another tip is to check your tire pressure frequently and make sure they are inflated to the recommended levels. Underinflated tires can increase fuel consumption.

You can also try to reduce the weight in your car by removing unnecessary items from the trunk or backseat. The more weight your car carries, the more fuel it will use.
