What kind of mileage do you get?

[Blue95]

Mine seems to get bad MPG on the hwy if I start the tank out in town/city for even 30 miles, but if I start it on hwy and run only hwy it is much better

Mine went to crap with the mud tires and possible winter gas being sold now.. 11.4 avg last tank.

 

[Blue95]

I am wondering when they switched to winter gas since mine has dropped some too

Just did a little maintenance. Last tank before tune up: 12.4 mixed

After replacing the spark plugs, corroded cap and rotor: 14.5 mixed and then pulling two barges full of ash logs I was still getting 12 mpg.

It helps to check those things once in a while, you know?

Good news... yes I dont know when the last time my plugs wires and cap/rotor have been changed.. I needs to do that

Last fill up with some gas treatment I'm gettin avg. 11 mpg's without going through town. Through town probably 8mpg

 

[Blue95]

Last fill up was 140 milesinterstate and the other 100 was 40mph and under and all kinds of lights and stop signs - 14.31

97 GMC Sierra with 3.73's and 305 70 r16 Maxxis Bighorn mud terrains on a 4 inch Rough Country lift with some heavy full replacement bumpers and I get in between 13 and 14 all city. I couldn't be happier with it I thought I would drop way off but not too bad.
