[OL'55]

So I picked up a 2007 Chevy Colorado 2.9 5spd, extended cab, 6ft box.

I filled it up on the way home and figured I would get a baseline and just drive it like a normal person would thru the frirst tank. That lasted about 50 miles and I couldnt help my self and started driving more eco minded. At 100 miles I inflated the tires to 44lbs (max sidewall rating), at 150 miles I took off the heavy steel contractors tonneau cover. At 250 miles I took off both mirrors. At 270 miles I cleaned the MAF and throttle body. None of these made a noticeable increase in MPG.

Temps have been 45-60 over the last couple weeks and its been pretty windy. I drove maybe 50-70 miles taking loads of broken concrete to the recycler. Other than that the scangage has been reporting 24ish for my 7 mile trip to work, and one 80 mile freeway trip at 30mpg. I was fairly happy.

Today I filled up...21.87mpg for the tank. Scangage was a little off, I never had a trip that low, even hauling concrete. Hopefully next tank comes out better but Im not holding out a lot of hope.

Maybe after a few more mods? Would like to see 30 mpg averages.
