Need help with Chevy truck mileage

Things that don't fit anywhere else...

Casey,
I looked up rear end ratios, and find that it can help with highway miles, but not so much with in town driving.

Mark,
The fuel management system sounds good for highway miles, but 99% of my driving is stop and go in town.

The other Mark,
Yes, I run with a service bed of sorts.
It is slightly heavier than a standard bed, and it doesn't help fuel mileage.
In the past, it has worked out to a 2-3mpg decrease from having the different bed.

I've had everything from a 454 1 ton camper special (9mpg) to an S-10, (12mpg) all with service beds.
My current truck, a 97 Cheyenne 1/2 ton with a 5 liter V-8 started with 12-13mpg 11 years ago, and now gets 9-10mpg (has a lot of miles on it...)

We also have an 04 Denali with the 6.0 liter engine.
It gets 11-14 mpg...pulls the trailer very well!
It is used by my wife to go back and forth to work 1 mile each way, and for vacations.
The mileage sucks, but we don't put enough miles on it to make much difference.

My employer will be buying this truck and the fuel, and thus has requested that I find a more fuel efficient solution.
It seems that 12-14mpg is the across the board norm for work trucks.
Going with a mini truck to save fuel works fine if the bed is empty, but if you actually need to use it as a "truck" then the mileage is no better than the full sized trucks.

I can see where buying a smaller, underpowered vehicle might look good on paper but what will that cost on the job by requiring you to be more selective on what tools/materials you bring along due to space or weight limits. When this came up on my last job I suggested we simply equip every substation with all the tools and test equipment we needed and then issue us all Harleys instead of service trucks, to save all that gas we were wasting in those 3/4 and 1 ton serviced trucks with service bodies or tool boxes. I'm sure the Tuttles could come up with a chopper that had a "manlift/bucket" in place of a sissy bar............ :lol:
Needless to say, we ended up staying with the same type of vehicle we had always used and continued to use 6 litre and larger engines.

That could work!
Heck, I'd even carry my tool pouch on the bike!

Even the beginning mileage for the 97 was below what I would expect for that truck even though it has a vortech fuel system which was not good for fuel mileage. My point being all about the expected load. A bit larger engine will get as good or maybe even a little better than an engine that is a bit undersized for the work to be done. Just be wary of a rear end ratio that is too low or you could end up with bad mileage loaded or empty.

But there is no substitute for a low ratio if you are going out to pick up a serious load, just don't expect to get there empty without burning a little extra fuel. Gear ratio really kind of makes the difference between a truck shaped conveyance and a TRUCK.......... :thumbsup:

Thanks Ricky!

Interesting that the small V-8 gets better in town mileage than the 6 cylinder...

I had a Chevy 1500 with the V6 and 5 speed. 20 mpg every day and 23 once in a while. Traded it off after 240,000 good miles.

Bought a Dodge 1500 with a 4.7 and 5 speed automatic. Gave up a mpg or two, but gained a lot more power and comfort.

Would have bought a new Chevy V6, but the mileage had dropped a couple mpg, making it almost the same as my Dodge. This time, the Dodge met my needs.

I miss the simplicity of the old V6, and wonder if my V8 will go as many trouble free miles. Some how I doubt it. Hope i am wrong!
