What is the best way to increase the fuel efficiency of my Ford Mondeo?

I recently purchased a Ford Mondeo and I'm looking for ways to improve its fuel efficiency. Are there any specific modifications or maintenance tasks that can help me achieve this?

Regularly changing your air filter and getting your engine tuned up can greatly improve the fuel efficiency of your Ford Mondeo. Also, make sure to check your tire pressure regularly as under-inflated tires can decrease efficiency.

Investing in a fuel injector cleaner and using a high-quality gasoline can also make a noticeable difference in your Ford Mondeo's fuel efficiency. It may seem like a small step, but it can make a big impact in the long run.
