In the United States, the Powerstroke is a $4000 option while in Canada it is $7500 extra. The other major factor when it comes to cost is that Ford has limited the diesel to its Lariat and higher trim trucks, so the brand has made it essentially a luxury option. The cheapest F-150 diesel you can buy in the US is about $45,000, while in Canada it sits at about $58,000.
So right off the bat, your 3.0-liter Powerstroke truck isn’t going to come cheap. So where can you save with a diesel? Fuel consumption is the probably the biggest one.
Fuel economy is rated at 22 mpg combined and 25 mpg highway for the 3.0-liter diesel with four-wheel drive, while the two-wheel drive version does manage 30 mpg highway and 25 mpg combined. In Canada, the truck is rated at 10.7L/100KM combined with four-wheel drive.
