All this makes the 15mpg in my S-Jimmy look frugal!

My Durango R/T got 10-11 mpg.  My theory is the engine was designed to use gasoline as a lubricant and coolant.

International Scout II, with the 345.  As the speedometer went East, the gas gauge would go West.  Going up any steep highway, you could watch the gas gauge go down.  Great truck, owned it for a few years, sorry I sold it.
