What is the best fuel-efficient engine for the Ford EcoSport?

I am looking for a fuel-efficient engine for my Ford EcoSport. Which engine option would be the best for saving on gas? Any recommendations and personal experiences would be greatly appreciated!

In my personal experience, the EcoBoost engine in the Ford EcoSport has proven to be the most fuel-efficient option. It delivers impressive gas mileage without sacrificing performance.

I have found the diesel engine to be the most fuel-efficient for my Ford EcoSport. It may be a bit noisy, but it's worth it for the savings at the pump.

For a more budget-friendly option, I would recommend the standard gasoline engine in the Ford EcoSport. It may not be as efficient as the other options, but it still offers decent gas mileage and reliable performance.
