Kev,

I am getting around 10.8 mpg and I now have 11300 miles. I will keep you informed after the performance mods are done. BIG-C

10.4--I stared at that Number for the better part of a year. I've changed oil 4 times. The last two were Synthetic. I picked up 1 MPG on the first change. One week ago, I had the second change and now stare at 11.9-12.4, go figure! The rest of the drive-train is soon to follow.

I suppose this falls into the same category as Dicemans post on the fuel saver, and will most likely render the same response. My Experience is, --THIS--snake oil worked for me. Might be reconsidering one of those fuel savers just to try--Hell .5 or more MPG, still adds up!

Anyway, with 17,383 miles on my rig, i don't think these are bad numbers--since it isn't even "broke-in" yet.

. . . You all should see a jump of about 1-2 MPG around the 5K mark as the computer keeps the fuel mix rich for engine break-in. I am now seeing 11-12 in town, 12-14 highway, less so when the temp drops. . . Ric >>


I have heard this from others too, but I saw no noticeable increase in mpg after 5000 miles. I am at 12000 miles now.
