I have tried most things I can think of, and I simply can't get to 20 mpg on the highway. (19.0 is the most I can muster pretending there is an egg under the gas pedal traveling at 75 mph on road trips) I have a 96 country with 205K, 1" lift front and rear, 235-75-15 Michelins, cone air filter (not cold air, it gets hot air), 180 degree thermostat, etc. I have also tried running up to 37 psi in the tires, with little help. Does cold intake air increase or decrease gas miledge? (I know it increases power). Will switching back to the 195 degree tstat help? I know I have a lot of miles, but the engine is kept in tip top tune and I run 10W30 Mobil 1, never uses a drop. I always read on here about guys getting 24,25 or more mpg with 4.0s, 4wd, and auto, which is what I have, so help me do it!
