1995 Regular cab, 3.0, short bed, automatic, 4x4
K&N filter, Taylor Wires, this Winter 235/75/15 snow tires, 3.73 or 4.1 gears, (I forgot) I now have an aluminum cap but those never made a difference for me.
Winter around town ~15- 16
Winter highway ~17.5 heavyfoot
Winter highway 55-60 mph ~19.5
Winter hubs locked and 4wd 55 mph, 20% city ~17.5
3 season city 16-17
3 season hiway 17.5 most tanks heavyfoot. (less when really heavy)
Have not tried to lighten my foot in warm weather yet.
Some of the figures I see posted here are the stuff of my dreams. I can only assume the best are from 2wd manual or 4x4 manual if not specified. i wish the postings were more specific with the specs. I will check my gear ratio if someone wants it and to remind me how without opening the diff.
