Yesterday morning I threw in my scan gauge 2 and drove "normal" to work and it indicated 20mpg, on the way home I played around with speeds, gears, etc to see what effects what. 55mph on the express way and 45mph on the back roads netted me 22.5mpg for the trip home which normally is worse. That is WITH 4x4 usage due to slick roads on the way home. When I put it in 4x4, the mpg dropped about 12%, but I do have a miss matched tire in the front, and I suspect that is causing some extra drag. I'm thinking manual locking hubs would really help when I don't need the 4x4.
Anyway, last night I took the mechanical fan off and removed my grill block. No fan currently, but I have extremely little city driving, only 4 stop lights. I plan to install an electric fan before spring hits.
Hopefully the scan gauge says my mpg increased today, I'm sure it will since I'm going to leave a bit early and go slower.
Just some fun numbers (purely from memory before any mods but the grill block)
70mph warmed up - 19-21mpg
55mph warmed up - 22-25mpg
55mph cold (first ~10-15 miles) - 17-20mpg
45mph warmed up - 24-26mpg
35mph warmed up - 28-31mpg
MPG figures are not calibrated! But the % differences should be semi accurate.
