What is the most efficient engine option for a Ford Transit Custom?

I am looking to purchase a Ford Transit Custom and I am wondering which engine option would be the most efficient for my needs. I will be using the vehicle for both city driving and long distance hauling. I don't want to sacrifice power for fuel efficiency, but I also don't want to break the bank on gas.

I have owned a Ford Transit Custom for several years now and I have found that the 2.0L EcoBlue diesel engine is the most efficient option for my needs. It has plenty of power for both city and highway driving, but I also save a lot on fuel costs compared to the 3.5L V6 engine.

I highly recommend the upgraded 3.0L Power Stroke Turbo Diesel engine for the Ford Transit Custom. It may be a bit more expensive upfront, but the fuel savings in the long run are worth it. Plus, you'll have all the power you need for hauling heavy loads.
