How to increase fuel efficiency on a Ford Transit Custom?

I have noticed that my Ford Transit Custom is using up a lot of fuel and it's becoming expensive. What can I do to improve its fuel efficiency? Is there any maintenance I need to do or any driving techniques I should use?

One way to increase fuel efficiency on your Ford Transit Custom is to regularly check and change the air filter. A dirty air filter can decrease fuel economy by up to 10%. Additionally, driving at a steady speed and avoiding sudden accelerations and braking can also help improve fuel efficiency.

Another tip is to make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency and even cause damage to your vehicle. Check your tire pressure regularly and keep them at the recommended level.

Additionally, using cruise control on the highway can help improve fuel efficiency by maintaining a consistent speed. Also, try to avoid carrying excess weight in your Ford Transit Custom as it can decrease fuel economy.

Finally, regular maintenance such as oil changes, spark plug replacements, and keeping up with tune-ups can also contribute to better fuel efficiency. Don't neglect your vehicle's maintenance, as it can significantly impact its performance and fuel economy.
