98 3.0 MPG Log (shows how mods affected MPG)
I've been recording MPG for a few months now to see how recent modifications affected gas mileage. With all of the threads started about how to improve gas mileage I thought this might be of some interest.

the gasoline confuses me, is e10 ethanol? if not why did you not stick with the same octane gas until the new tuned setting? orrrr am I just reading it wrong ( the climb from 89-102 octane confuses me)
102 octane gas wouldn't be any more useful in our trucks than 89 if the truck wasn't tuned for it. you would just be wasting money at the pump.
Also what's the reasoning behind odometer and actual miles being roughly 30miles off?

The Odometer and Actual miles are a ratio of 1:1.113 to correct for my larger tires.

Yeesh, I only run 87 octane on my 3.0 and I average at least 18-19 City/Highway combined. A reason why I don't lift my truck and run 30" tires.
Some of my best highway MPG ever was around 26 MPG. I have underdrive pulleys to be delivered tomorrow and just installed new spark plugs, wires, and the demon coil pack. I'll be tempted to see what that does for my fuel economy. Granted, I think one of both of my O2 sensors are dying, so I haven't been able to obtain solid data henceforth.

I have gotten a worst of 21 and a best of 25mpg. I see a few around that get that. Guess I'm lucky.
I just looked again...you have a 4X4 or a $X$.
