Cummins mpg vs 225 Slant 6 mpg

Nobody asked if it was one of those pre turbo motors, if it is skip it...

yeah the pre turbo ones were early 1989, still worked good but not as much jam, but really good fuel milage

WRONG WRONG.

The Cummins motors in the dodges were ALL turbo. Not all were intercooled, intercoolers were put in mid 1990

Our 89, we've owned since it was ordered in 1988, is number 16 off the line. It is turbo'd, though tiny and non-intercooled.
