I was gettin 19 and now I get 15. I noticed the mileage drop after the implementation of ULSDF. I think that is what is causing my mileage drop. Does adding 2 stroke oil improve mileage? The reason I bought a Dodge Cummins was for the fuel efficiency but this is getting ridiculous. Im getting what my buddies Powerstroke is getting. Both engines stoke but hes got tons more power.

Maybe you guys can help me out with this.
I cant seem to get any more than 13 mpg out of this truck, and it really is getting a little nerve racking.
It is a work truck, it weighs around 11k on a regular basis, and tows about 12-15k on a regular basis.
Sometimes when I hand calculate the mileage, I only get 10mpg.
I have tried backing the fuel plate off, the starwheel off, and even tried howes meaner power cleaner.
I used to average between 16-18, but last tank averaged out to 12.8MPG.
I have done a valve adjustment too.
Where should I go from here?

I lose a mile or two in the winter and I lost a couple miles with the ULSD. Larger tires help if you have a 4.10. iwth my 35's I get about 17 with the ULSD. I hope to gain a little more by going to 37's. 1/2pound more weight but alot more hight to gear me down.
