I was getting around 25 highway till they pissed our gas down with corn. Now 21-22. All stock 215K miles.

Kane

14 mpg at continuous 65mph.
I get 17 when I keep it at 45mph in 4th and 5th.

I have very heavy bumpers , roof rack, 31x10.5x15s, and the aerodynamics of a brick...

My last #'s on the 87 2.6 turbo non-lockup a/t were about 20 at 75ish cruise on the flats, and about 18avg with a bunch of kickin' it around town/freeway, on regular. Premium added about 2-3 first case and 1-2mpg second case to that because the knock box let it run more advance at cruise with the higher octane.

At the 75ish cruise, I was seeing about 200-300rpms of converter slop that a lockup would have prevented. It ran at about 1-2psi of boost at that speed and load.

As of this afternoon, I've clocked an 'indicated' (144,000-84,500) miles and change on my 87 Raider. I say indicated because of the many tire sizes I've used adn that I haven't changed the speedo drive gear yet. . The best tank mileage I had oddly was in winter and with 33's...about 20.5 mpg 'indicated'. <img src="/forums/images/graemlins/scared.gif" alt="" />

My normal driving:
235's on stock alloys = 17 to 18.5 mpg
31's on 8" steel wheels = 11 to 19 mpg, range due to trailer towing in 4-lo and substantial highway with a single bag of dirt (250 mile trip for a bag of dirt!!)
32's on stock chrome steelies, driving up and down from Tahoe = 14 to 16 mpg
33's on alloys = 13 to 20.5 mpg

I carry many tools on a daily basis, use the truck almost strictly for work, and use 4-lo quite often.

There was quite a thread on this about a year ago. <img src="/forums/images/graemlins/kewl.gif" alt="" />

14 City 17 Highway. Depends on which way the wind is blowing.

Worst ever was 10mph in a 35 knot head wind near Lancaster.
Best ever was 23 with a 25 knot tail wind near Mojave

On my 89 SWB v6 w/out a non lockup torque converter, I recently got ~15mpg mixed mileage.

19 mpg tank after tank, doing the same drive: 70-80 mph from Northern Fairfield to Yonkers, NY on 684/287/Sprain Brook.

Tailwinds do seem to help, especially on the stock 2.6 5 speed I had from 87-99...it got 22 mpg max on hwy and 20 in mixed.
