If you cannot make that Prostar with an ISX CM871 turn at least 7+ or 8+ mpg.. then forget about anything newer!!!!.... --- something is wrong with the operations?. Perhaps the way you drive it?.. or that engine? .. and a newer truck is NOT going to be any better long term.

YOU ALREADY OWN A GSDDA#MN 9+ MPG TRUCK!!! --- WITH THE HIGHEST PROFIT MARGIN BRAND OF TRUCK IN THE ENTIRE INDUSTRY!!!...

IF IT IS NOT WORKING OUT FOR YOU.. THEN SOMETHING IS VERY VERY WRONG!!!... AND 90% OF THE TIME, IF IT IS A BAD AS YOU SAY.. IT IS HOW YOU ARE DRIVING IT, OR SOMETHING RELATED!.

ALL newer trucks and engines also have higher operating costs .. WITH ZERO FUEL OR OTHER FINANCIAL GAINS AT ALL (healthy engine and truck vs. newer healthy engine and truck) to justify the purchase. ALL the common rail engines are inherently LESS PROFITABLE over a million mile span vs a well cared for CM871.

A new truck is NOT going to fix this... but only make a whole lot of payments piled on top of the already unusually low fuel mileage that you currently suffer.

I know this quite well. I own a prostar with a CM871... and even at 1.4 million on the odometer.. it still breaks 9+ mpg with 80,000 lb coils in the box all day long.


-= MAKE WHAT YOU GOT MORE PROFITABLE.. squeeze it for all its worth. FIGURE OUT what is costing you your fuel mileage and other financial losses ... Then look and see where you are at.

I know that if I could do it ... So can the next person. It is called discipline and determination.

I have done everything to this motor possible and it still gets horrible fuel millage.
As for my driving I cruise at 62 never in a hurry always watching my pyro and boost gauges easy on the hills I've even been passed by Prime.
I'm at a complete loss.
And some work I'm looking at I will need a carb compliant truck... that doesn't excite me.
