How to optimize the fuel economy in a Ford Transit Custom?

I have noticed that the fuel economy in my Ford Transit Custom is not as good as it used to be. Is there any way to optimize it without sacrificing performance or comfort?

First of all, make sure to properly maintain your vehicle. Regular oil changes, tire checks and spark plug replacements can greatly improve your fuel economy. Additionally, try to avoid excessive idling and use cruise control on the highway to maintain a steady speed.

Another factor that affects fuel economy is weight. Remove any unnecessary items from your vehicle to reduce its weight and improve fuel efficiency. Additionally, avoid using the air conditioner if possible, as it puts extra strain on the engine and uses more fuel.

Consider switching to synthetic oil, as it can provide better lubrication and improve fuel economy. Also, check your tire pressure regularly and keep them properly inflated, as underinflated tires can decrease gas mileage.
