Re: Fram air filter for TJ-poor mpg
 

I'm the same as Mike with the xj, if I stay in the 'normal" range of 110-115
I get great mileage, less then 100 (if I want to be like the dumb stupid
#$%^&*&*& who insist on driving the 400's during a snow fall, when they
can't drive for ---- to begin with" then I get pretty close 26mpg. Yeah
the few times I decide to take the jeep into the warp speeds the posers and
rice burners do I get right down to 15-16 mpg. This of course is all
relative to how many transport trucks I decide to draft. :) In 2 weeks I'm
going North with the truck, I figure I'll get about 20 mpg depending on 3
things, 1 how many ricers I see, 2 how many transports I follow and 3 how
much of the trip the wife is awake for :)

Re: Fram air filter for TJ-poor mpg
 

You know, one thing I've been curious about is how the tire size will relate
to mpg - taller tires give you higher or lower mpg. I can argue it either
way in my head.

I went from 215 to 225 and saw doodle difference. Generally I think that
city mileage would get worse with taller tires (more power required to
accelerate) and highway would be better (lower rpm for a given distance)

I've seen a greater difference in milage from dirty air filters, fuel
filters, spark plugs, burned rotors, and vac leaks, than anything.

Re: Fram air filter for TJ-poor mpg
 

Hi Ken,
It takes more energy to turn the larger tire because of it's
heavier weight.
