I bought a '73 CJ5 w/ a hot 327 Chevy :twisted: in it last week and used my Coly to trailer it 260 miles. My last fill-up I got 12.3 MPG, all town miles, not very much idling time, and drove pretty much like a grandma. Got 23.3 MPG about 3 weeks ago all highway, my best ever. I usually average 16-19 over the last three years. Pulled my Jeep and trailer (around 4500lbs) and got close to 17 MPG. What the crap? How does pulling weight at 24-2500 RPM give me better gas mileage than driving like a grandma around town? My truck runs great and sounds great, but I just don't understand it. :? Oh and I have to replace a blown intake manifold gasket on my Jeep, so that will be fun, lol.
