How to improve gas mileage on my Ford Transit Custom?

I have a Ford Transit Custom and I've noticed that my gas mileage isn't quite as good as it used to be. Is there anything I can do to improve it?

One way to improve gas mileage on your Ford Transit Custom is to regularly check and replace your air filter. This can help your engine run more efficiently and use less fuel.

Another tip is to avoid aggressive driving and excessive idling. This can waste fuel and decrease your gas mileage.

Properly inflating your tires can also improve your gas mileage. Make sure to check your tire pressure regularly and keep them at the recommended level.
