3/4 ton mileage

[jp0863]

Folks with a 3/4 ton both diesel and gas, what kind of mileage are you getting?

Pretty variable answers to this question. A friends 91 burb 350 with 3.42 and 33s gets 12-14.
My 91 4.10 geared 35" crew cab gets 10.

Never checked it. If I knew the truth it might ruin it for me. I just close my eyes and fill it up. 91 V3500 crew.



My 2006 and 2010 3/4 GM work trucks really only managed about 12 anyway.

10,,,up hill, down hill, trailer, no trailer.
99 Burb with 454/4:10's & Texas hills (damn near flat)

When I think about gas mileage of my tow rigs I always think of CAMARO....which is an old Native American word for "Fill this F*cker up again".

Not a 3/4 ton but the weight difference isn't too much. My 84 6.2 pulled down 20 on the highway. Got 13 towing a full size blazer. Which was good considering I had it matted the whole time. Stock size tires 3.73 gears and a 700

Current 3/4 ton burb 2wd big block 10.5 empty or towing a small load ( under 1k) around 8 towing. 3.42 gears stock tires and a turbo 400

My '82 K2500 pickup with a 6.2 / TH400 gets about 15 mpg no matter what I'm doing with it..dont know the exact gearing,I'm guessing it has fairly high gears because it can hit 60 in second gear or a bit more before the govenor starts kicking in..
A Burb might get less,since they are heavier..never had my '85 K10 Burb with a 6.2 / 700R4 on the road,it has 3:73's,I doubt it would be much better on fuel..

88 3/4 ton, 2007 LQ4, 4.56s.
I am at 9-14mpg depending on venue and foot angle.

My 89 burb 350/700r4/4.10/31.5" tires gets 12-14.
When I had the turbo diesel burb with 700r4/4.10/33" tires I was getting 20-24, but was before the ulsd.
I know with all my diesel vehicles I lost a few mpg with the nee fuel.

Pulling a camper uphill = 5MPG. Pulling a camper downhill = 35MPG. So I average 20MPG, right?

90 3/4 ton burb, 2wd, 6.2, turbo 400, 3:73s 17 mpg. It would do better with overdrive & 3:42's I'm sure.

 

[sreidmx]

16 with 6.2 diesel and sm465 on 3.73 gears and a 34 inch tire, and with the 5.3 ls swap and best was 19mpg on same axles with an mv4500.
I get 13 on e85 in the ls.

So far driving to Boston 14 to 12 just depends on how hard I hit the skinny peddle . talk to a couple of guys today with new 3/4 tons Chevy crew cabs 4x4 they are like 13 and Dodge are under 10 in the city so my old 1990 suburban with a new crate engine with 650 dbl 2500 stall th400 3: 73 with 33x12:50r15 not to bad

Not uncommon to see 19mpg in the Wife's 98 6.5 Burb, 3.43s. With ~42 gallons of fuel it's a real bladder burster!
