MPG Spike

[FLynes]

For the last few months I've been lucky to get 19. 7MPG's max on my 05..... usually it's between 17. 8 and 19. 7. It's obviously a CTD, has the 48RE, manual 4wd shifter, 3. 73 posi rear and has no mods, with the exception of a Mag-Hytec DD trans pan. I filled up at Citgo yesterday and drove around for a bit, then today I drove in to work, which is 45 miles away from home. The computer is saying 23. 1MPG's. I have no idea what the heck is going on..... the needle is in between full and 7/8's and the tripmeter is reading 139. 2. I'm confused on this. I regularly use Howes Meaner Power Cleaner, and occasionally Power Service which I added on the last fill up, but not this one. Anyone got any ideas?

Ignore it. Just calculate your mileage at the end of the tank and compare it against the average from all the other tanks. Intermittent values are unreliable and so is the overhead.

Moving into summertime... no more blended fuel. . may account for a little better mileage
