Gas Mileage for 2500 series (3/4 ton) suburban or Yukon XL
John Spurrier
like to know the gas mileage for the 6.0L and 8.1L engines for City/Hwy also
if anybody has towed or know of someone who's towed about what mpg they got.
I would appreciate that a lot
Thanks

directly relate to towing limitations. Specifically, are there light versus
heavy duty features like 1/2 ton versus 3/4 ton ?
The difference in weight of those features usually affects gas mileage and tow
rating.
The available rear end gear ratio greatly affects the tow limit and gas mileage.
And of course the optional engines like deisel .
Diesel engine may be more economical for a high mileage tower. Many of us
chose gas over diesel engines merely because of the excessively long time it
takes to pay back the extra cost of purchaseing this option. A calculation
for the difference should be made to determine if it's
cost effective for you since you say you are a high mileage tower.
I have the year 2000 3/4 ton silverado 4 by 4 ext. cab truck with 6
liter engine and 3.73 rear.
My mileage is 12 mpg [without tow load ] with short 8 mile trips to work....
but total miles per year about 13000.
It would take 7 years for the deisel option to break even on the extra cost of
purchase in my case.
I tow up to 1000 per year or 10 percent of the total milage.
However your case is different.
My mileage drops with tow load and the actual amount has not been measured.
Since gas costs and purchase price costs vary, there is no one answer.

*****************************************************
You need to look for the rear axle ratio matched to the 6 liter engine in the
suburban to compare apples to apples.
A 3.xx rear versus a 4.10 rear will have a dramatic affect on any given 6 liter
engine.
Two to three cents per mile and up to 1200 pounds difference in tow limit.
Also, ensure you have the right combination of engine/ rear end axle ratio in
the 3/4 ton to handle the tow loads safely.

Your 2002 Extended cab K2500 6.0L Vortec with 3.73 gears gets 12 mpg.
My 1995 Suburban K2500 7.4L TBI with 4.10 gears gets 11 mpg.
Are you happy with the mileage you're getting? Mileage means nothing to me but I see a lot of marketing poop that claims 6.0L Vortecs get way better mileage than that. Is this just more GM BS?

Damn, dude ... 11MPG with a big block and 4.10's, you keep your engine in good
shape!
I'm seeing 11MPG on my new-to-me 350, 4.10's ... but she's a 1990 with 170K
miles and an uncertain previous history. [Bought the truck cheap on the
premise that crate motors are cheap ;-)]

pkgs. i tow a 29' air stream trailer that weighs approx. 6800 lbs. and throw
my harley in the back, so in total i haul about 7500 lbs. i regularly get
10.5 to 11 mpg. at 65 to 75 mph. hope this helps. john

going from a 4.10 to a 3.73. Makes the difference in engine rpm of about
300 rpm. Not much difference, but it does affect performance some. If you
are buying for towing, go 4.10. It's better to have a truck that pulls well
and gets a bit worse mileage than a truck that pulls just OK, but does a bit
better fuel economy. Give me power when I need it and I probably won't
notice the extra fuel I'm burning.

I have paid the money and I am stuck this reality.
The 1/2 tonvortecs are definitely better on gas but they are light duty trucks, etc..etc..
The diesels are not cost effective for me given all factors of costs and miles driven per year.
Since the capacity of the truck meets/exceeds all my requirements... I ' ll keep it.

miles 12.5 back and forth to work. No towing yet. First trip out will be in
May.

average city/highway combined when not towing. At 65 mph on the highway, I
will sometimes break 14.0 mpg. Depends on the direction the wind is
blowing. But, if someone with the short bed and 3.73 gears is only getting
12 mpg, I would say something isn't right.
Towing: too many variables for the relatively short trips I have gone on.
Most of our camping trips have taken less than 1/2 a tank of gas to get
there, and I haven't bothered to fill that half up just to find out. Still
averaging 11.0 to 12.5 mpg on those tanks.

just over 1,800 miles on it. I haven't even put a second tank of gas in my
2500HD yet as I've only put 165 miles on her! It's just approaching a half
tank. I have the 6.0L w/ 4.10 rear. Hopefully I'll sell the '95 Yukon soon
and will begin driving the 2500HD daily.....
