I cant afford to drive my Stroke

[toast]

Ever since I've modded my PSD, my gas mileage has gotten worse. I didnt mind at first because I was "testing" the settings with a heavy foot. My mpg has gotten worse since I stopped beating on it. No matter what tune, even stock, I cant get better than 14, usually 10-12. Towing is 8-11 mpg. 8 mpg towing two cars on a 32 ft goose, and 11 is towing the goose empty. What gives?! Any suggestions where to start?

It could be the winter blend fuel. mileage tends to go down because of that. are you using diesel kleen or any other addditives with it

I agree it is probably winter diesel. My milage drops 2mpg every winter. You can also do like me and build your own Bio processor. I will be making my own diesel for about $.75 per gal!!!

i noticed my MPG going down the tubes once winter hit. i didnt think they had a winter blend for diesel but i guess i was wrong. they should have one blend. the one that gets us better MPG.

My milege is stuck @ 14.4, since winter blend started w/ Diesel Kleen. And w/ my winter tires, studded 285's.

I agree that it is the winter fuel. I notice that every winter my mileage drops by about two miles to the gallon. Typically I get 16-17 during the summer and then 14-15 during the winter. The additive helps a little but not much. I still would recommend the additive just because of the crap fuel.

I have not put any additives, but I picked up some. I thought all of these mods were supposed to help with mpg....I was getting 18 before I started...

I have the best suggestion. Sell me your stroke. I'd love to have a 7.3 with only 39K on it. Then I could still drive a powerstroke when my 6.0 inevitably breaks.

Sorry to bring up an old thread but I took another trip to Utah with both Jeeps. In the mountains I got 5.7 mpg average for an entire leg of the trip! With the summer blend, I still could not break the 14 mpg mark.

A diesel mechanic suggested I remove the tuner to see what happens. I didnt personally drive it, but my nieghbor borrowed it yesterday to move some stuff from college. 210 miles, and back up to 20 mpg. She said she didnt go faster than 63 however lol. I guess the "stock" setting still isnt stock. Good god its a slow SOB now, but I can almost afford to drive it!

tuners never give worse milage unless you have a heavy foot or something wrong with the truck.
