How to improve the fuel efficiency of my Ford Transit Custom?

I have been noticing that my Ford Transit Custom has been using a lot of fuel lately and I'm not sure what to do. Are there any ways to improve its fuel efficiency?

One way to improve the fuel efficiency of your Ford Transit Custom is to make sure your tires are properly inflated. Under-inflated tires can cause your vehicle to use more fuel. Regularly checking and inflating your tires to the appropriate pressure can save you money on gas in the long run.

Another way to improve fuel efficiency is to avoid unnecessary idling. If you're parked and waiting for more than 30 seconds, it's more efficient to turn off your engine. This can also help reduce emissions and lower your carbon footprint.

Keeping your vehicle maintained can also help improve fuel efficiency. Make sure to regularly change your oil and air filters, as well as getting tune-ups as recommended by your vehicle manual. This can help your engine run more smoothly and use fuel more efficiently.
