The right engine can make a big difference in the cost of operation and maintenance. So, what semi truck engine gets the best fuel mileage?

Finally, there are several options for light-duty trucks that get great fuel mileage. The Ford 6.7L Powerstroke V8 turbo diesel engine is one example. This engine has advanced features like a variable geometry turbocharger that help it achieve excellent fuel economy while still providing plenty of power.

Conclusion:

When looking for a semi truck engine that offers the best fuel mileage, it’s important to consider the type of truck you’re driving as well as your specific needs and budget. For heavy-duty applications, the Cummins X15 Efficiency Series diesel engine offers excellent efficiency ratings; for medium-duty applications, the Paccar PX-7 is a popular choice; and for light-duty trucks, the Ford 6.7L Powerstroke V8 turbo diesel is an excellent option.
