cleaners, which keep them in tip top condition for the best fuel

The 6.7L Scorpion engine was an all-new in-house Ford design in 2011, which has proven to be very reliable compared to previous generation Powerstroke engines. The fuel system components are even more precise, allowing for extremely high pressures and multiple injections per cycle making them quieter, more efficient
