11mpg?! ouch...
I did 15.5 when I filled up last night as well as the fill-up before that.
since you have oversized tires, is your speedometer corrected for the tire size? where are you getting your miles per tank from?
I use my in-dash navigation to pull miles since my speedometer is off. GPS doesn't care about your tire size

So you are basically adding 1qt 2cycle oil to a full tank of fuel?
I have also heard of people mixing in used tranny fluid in their fuel, has anyone else heard of this?

i have seen people use ATF fluid but that was in a powerstroke, but haven't seen it in a cummins. not to say it wouldnt work just saying idk anyone who has used it. the guy with the 7.3 had a transmission shop and he ran it through a few filters, and im pretty sure he cut it with diesel too. if you google it you can prolly find the article. IDK how it does for fuel mileage though. I also get better fuel mileage with my tuner on the power setting. i have a quadzilla xzt+ so it only has three settings. power, mileage and stock. You just have to keep your foot out of it. Are you running any mufflers or cats?
