dats cause it wouldn't go any faster no matter how much gas you gave it.

Reading all of this makes me feel better about my mileage. I get 11-12 around town with some freeway peppered in and 13-14 pure freeway. My truck is as modified as the rest including 35s and all the bumpoer weight. The 4.56 gears probably help just a tad. Idrive with the PWR always on.

This is going to sound crazy, but my mileage has improved by a slight amount since adding the RTT. I think the gigantic basket I had up there previously created more drag than the sleek Maggiolina Grand Tour. I mounted the RTT as far back as made sense (removed the rear spoiler wing) so that air flowing over the windshield could continue right over the RTT. There is substantially less wind noise with the RTT than I had with the basket so I figure this correlates with the better fuel economy.

One more thing, I also noticed that I get slightly better mileage with the regular snorkle attachment facing forward than I do with the swirling dust bowl attachment. Ram air effect??

Anyway, my mileage test are done over hundreds of miles since it's not accurate if you just do it off one or two tanks.

Has anyone here tried "pulse and glide" technique?

Driving technique: exploring 'Pulse and Glide' - MetroMPG.com

Pulse and glide works like this: let's say you're on a road where you want to go 60 km/h. Instead of driving along at a steady 60, you instead accelerate to 70 (that's the pulse), and then coast in neutral with the engine off down to 50 (that's the glide). That's it. Rinse and repeat. And repeat. And repeat...

stupid and dangerous as well as a ton more wear on your starter. try to steer with the power steering and then have it cut out... then back on again... at 60-70mph? On a 2 ton suv?

To risk your life and everyone around you for what? a few mpg gain only at the time you are actually doing this idiotic behavior
so with a full tank of gas, you have gained 5 miles or something. BFD. Put more air in the tires and you will probably get better mpgs than morons-r-us.

Does anyone else put it in Neutral and coast down hills? I do this only when safe and I can maintain my speed. I recently went 12 miles, when coming down from Sierra Summit back to Fresno (yeah, hurts every time).

Not to hijack, but I can't do this anymore as I now stall when coasting. Maybe an altitude effect, and probably a symptom of a sensor problem. Any ideas? PM

Funny, I did that only once in my 80 driving down from Kings Canyon National Park to Fresno as well. Hand on the shift, ready to turn off the O/D, anyway. You need to have a real clear road ahead of you and I would be extra careful in the curves because you obviously have less grip when in Neutral.
I remember having done that in Greece back in 2000. There was a major shortage due to a truckers strike and every drop of fuel was precious.
Back to the 80: I just had all injectors changed. Wondering how it's going to impact my MPG, which wasn't awful for such a rig.

Huh??

 

[1shot1kill]

38s will get you 16 to 18 mpg!
Seriously, are you driving her less with gas at 4 plus dollars a gallon?

How the hell is it my 1987 Chevy Suburban with 4"lift and 35" tires and 4.55 gears and stock TB 350 gets better MPG than my cruiser? Thats insane....I know I know, its the full time 4wd right

 

[lexuslx450buyer01]

the nicer the truck, the s***tier the gas mileage

 

[Mace Bigelow]

Im getting about 220-260 miles out of my fillups. I been wanting to really gauge this until I saw some guy post up his original MPG sheet from a factory LC-it was 12 City 15 hwy and thats with stock tires.

What are you getting in that truck? 14mpg?

How is your LC set up?

I'd imagine it's because your Sub has a better power to weight ratio than the overloaded 80

 

[walleyefisher]

I get about 16/17 hwy and 13/14 city in the burb.

Funny how an inline 6 banger can be such a gas pig.

 

[kidatari]

I get 8-9 MPG on my Supercharged '93 with 33's. And that's on premium

Just hit $4.49 in Sacramento today, my wallet hurts.

I need to figure out some engine management on this thing quick.

I used to do this coming back from skiing as a dumb teenager. But that was in a stick shift (pick the right gear and compression started on the fly) beater with power-nuthin. I wouldn't try it in a 5K SUV with power steering, brakes and an auto tranny. Oh, and without the engine braking, you may be in for a big suprise when you reach the turn at the end of that long hill.
