How can the Ford Transit Custom be upgraded for better fuel efficiency?

I have a Ford Transit Custom and I love using it for my business, but I can't help but notice how much gas it consumes. Is there anything I can do to improve its fuel efficiency without sacrificing its performance?

One way to improve fuel efficiency is by tuning up your engine regularly. This includes changing spark plugs and air filters, which can greatly affect your gas mileage. Additionally, make sure your tires are properly inflated to reduce rolling resistance.

Installing aerodynamic accessories such as a front air dam or side skirts can also help reduce drag and improve fuel efficiency. You may also want to consider switching to premium gasoline or using fuel additives that claim to improve MPG.

Another tip is to avoid excessive idling and heavy loads. The more weight your Ford Transit Custom carries, the more fuel it will consume. So try to declutter and empty your car of unnecessary items, or use a lighter vehicle for shorter trips.
