14.3 for me, see what summer time brings. My 05 with the same temp. 19.6
GMC 2500HD Crew 6.5 bed LBZ W/ DiamondBack Cover +/- 300# in bed.
SE region of PA. Short hops to football practice, staples(beer,wine), project site visits(work out of my Van), family typical runs w/ the 15mile run on the highway to get here and there, mostly Suburban mix type driving. I drive more towards the aggresive side but not like an A hole.
13.5K miles best average by hand calc. is 15.6/ Straight HW is aroung 18.5
pulling a light 3500# Boston Whaler.
We filled up in Thurmont Md. I added some Lucas fuel treatment and also DP cetane boost to the fill up. Then we drove to the Farm show complex in Harrisburg, PA. and back. About 140 miles round trip. 55 to 65 mph. semi Hwy and urban driving. The computer said I averaged 15.9 mpg. The truck only has 1,070 miles on it. I guess I will know how accurate the computer is after I fill up agin and hand calculate.
Filled up on the way on Hwy 15 and ran 108 miles at semi hwy speeds. 55 and 65 mostly. Went to Harrisburg, Pa and back to Rocky Ridge, Md. Drove 4 miles to town and topped it off 7 gals. We averaged 15.7 mpg. hand calculated. The computer said we averaged 15.8 and said we used 6.9 gals.
It was pretty acurrate. Only have about 1100 miles on the truck, so it should get better. We were empty not towing and it was 35 to 40 f. outside.
Just running around town and back country roads the computer say's about 13 mpg.
I just got mine Wednesday (crew cab, 4x4, 6 1/2 foot bed), my first tank was 13.7 mpg. So far all of my driving has been city. My previous truck was a 2005 extra cab Z71, it was nice, but I really like the diesel so far.
Has anybody tried condition consistent back to back runs in 5th vs 6th gear?
I'm wondering if we won't be surprised. 60 mph is my suggested speed for this test...
Got the LBZ full up from the dealer. Just filled up for the first time. 16.66mpg. Diesel is now cheaper than even regular gas around here. First time I filled a tank over $75.00 worth. the system just stopped right at $75. I had to reinsert my card and do another coupla gallons! Anyway, for a first tank and mostly city driving I thought that was okay mileage.
That's actually pretty damn good considering that it's fresh off the lot and hasn't had a chance to break in yet. Mine didn't get consistent 16 (city)/18 (combined) until i hit nearly 5k miles and had already changed the Oil.Quote:

As i drove past a bunch of stations today, Cheapest 87RUG - 2.98 (ARCO aka Cheap-Gas) And Diesel from my favorite station was a modest 2.77 (up from 2.68 Last Week)
The Gas vs Diesel price is sort of a wash, as one can't really predict why all of a sudden prices shoot the way they do.

Notes:
- This is not the most conclusive (as far as fuel prices go, i may not have shopped around the best).
- There are several fill-ups missing, most notably in the beginning and some in the middle, due to lost receipts :-P
- Note the best tank avg of 18+ mpg (made it back from Vegas on 1/2 tank, getting 22mpg @ 67mph, then kinda wasted the 2nd half of the tank.
I still like my Diesel though. Don't think i'll go back to a Gasser anytime soon, not in a truck anyways.
I have installed the Edge Evolution and have the #3 tune installed. Using the DIC alot, but it seems very close to actual when I compare.
I used to get 16-18 with mixed driving, now I am getting over 20 with mixed driving :D
I do hear a little more rattle, but not much and for this MPG I can live with it.
Roughly 18 - 20 MPG if I don't put my foot in it, but what the sense, if you can't show off. :cool:
I've been averaging just over 17 with mine, As of this morning I now have 1011 miles on it, havent taken any long trips yet. mostly city driving and about 100 miles towing my 16,000 trailer/backhoe.
My most recent tank gave 19.6, and that was winter blend. Must be breakin in a bit with 7000 miles. I`ll be doing a trip this weekend of 400 miles so hoping to break the 20mpg barrier
16.7mpg hand calculated. DIC said 1mpg less. I love this 34 gal tank!
466 miles on the tank netted 21.47mpg my new best ever! 80 miles was local to work and back. the rest was cruising @ 65mph. When the gauge was 1/2 it showed 410 mile and I was hoping it was getting 24mpg but the gauge is not real true. When I filled, the gauge was 1 mark below 1/2 and took 21.7 gallons.
Exactly what I was gettin while it was a stock motor. Now I ain't callin BS on those that say 20mpg + on a stock motor...but yaz got me wonderin for sure..!!:confused:Quote:
I have an 06 LBZ CC SB, and have been seeing anywhere from 14mpg (all streets mostly), to about 18 on the highway
Now....after mods
City 16.2 - @ 35 mph or better
Hwy 20.2 - @ 75 mph
Truck is MT, stock tires (60 psi front -50 back), and running the Banks at Level 4, driving was done daytime, springtime and on fairly flat terrain.
To get any better, I think I'll need a sail.:cool:
rgds,
stk;)
13.5 with 45 miles on the clock.
Is it broke in yet?

You've already got a sail. Those clever marketing guys just call it a tailgate.:DQuote:

I towed my 19' boat (4500 pounds boat and trailer) 210 miles Friday night and it got 16.1 mpg at 65 mph, 99% interstate highway calculated. On the return trip without the boat also at 65 mph, 20.3 mpg calculated. I had the a/c on both ways. Ed
2006 sierra quad cab, 4x4, best i ever got was 25 mpg highway doing about 110 km/hr
I have a 2500 HD Crew cab 4 inch lift LBZ I used to get about 9.9 towing(8400lbs Fifth wheel) and about 14.3 not towing on the Highway. I put on a Banks Monster exhaust, and Banks cold air intake, and I used a Superchip programmer. Can you say Rocket. I towed a Aluminum car trailer and a Chevy Caviler 400 miles with the new upgrades with 4100 pounds and 15.7 mpg I could not be happier. (55-65) Climbed the Grapevine in California twice during this trip. I was very reluctant to do anything to my baby. But it seems this was the right choice. Goes very fast if you let it, or make it. I look forward to visiting the pumps again. 500 Hp up from 360hp stock, 740ft lbs torque up from 650, according to the very happy parts man who sold me all this shiney stuff for $1800.00 . I figure I am saving 10.00 per 100 miles driven just while towing mind you and you gotta love that. Now if I can just keep from showing off at every stop light I will be doing very well.
