Woo Hoo! She's getting better with mileage. Just returned from another 900 mile trip and the CTD did awsome as usual. 75mph with no load, just truck and two passengers, 17.8 mpg! That is the best to date! Trip was from Louisville, KY to Milwaukee, WI (read: all flat). Truck now has just a tick overf 6,500 miles on the odometer.

Take care.

 

Patience grasshopper, wait till you get near 20,000

 

what happens at 20? I've got 22k and i'm averaging about 16.5 using the psd/mmo mix... which BTW it seems that I get about .5 better mpg if I use 20 oz of psd.

 

usualy around 20K eveything has seated and fuel mileage wont be increaseing drasticaly by that point.
