Give your truck a tune up. No reason for 11MPG.
I posted a short time back that I was getting almost 15 MPG on my 99 quad cab 4x4 2500. I drove it 197 miles today . Half that was empty and half was picking up an 18 foot davetail car trailer and coming home. Only about 50 of that was interstate, The rest was backroad 60 MPH driving. My lie o meter is saying 15.7 and my math has it a tad higher. My truck was eating fuel when I got it, but I did a tune up with quality parts and fixed the intake plenum. Now I am pretty happy with the mileage. And I have 4:10 gears. These trucks have a bad name for poor fuel economy and I can only assume theyere are alot of them out there that arent running well, Or are jusr worn out. I cant see any other reason for getting 11 MPG around town other than stomping the heck out if it at every take off.
