If you REALLY need the power for towing, go for it. From what I've seen and observed (and I work at a chevrolet dealership in the service department). You'd be best to get the max if your really going to use it for what it's intended for (towing larger loads). The differance in mileage is minimal, I've seen max's come in with an average of 13.7, but I've seen them with 9's too. It all depends on the situation and driver. Same goes for the 5.3. I've seen em as high as 19s average and as low as 11-12.


The 5.3 will be sufficent unless you haul big loads and do it often. Then the 6 is worth its weight in gold.

I have the 4.10s and I'm averaging 12.5 around town on 89 octane gas. The best highway average for me was 16.5 when it only had 1,000mi on it. FWIW I have about 8,500 miles now.

I have an 1500HD as well. Mine has the 4.10 gears though, I'd like to have a 5.3 right about now ;) best I've ever seen out of mine is 10-12 :) It's been a great truck for what it's worth, and will tow just about anything I've ever hooked up too, stopping on the other hand is something different ;)

I have a 2008 Crew Cab 4X4 with the 6.0 VortecMax, Trailer Max package, and 4.10 gears. Only about 2500 miles on it so far. I have a GMPP CAI and Magnaflow catback.

Back and forth to work, 1/2 freeway and 1/2 city, I get about 15. I did a 100 mile freeway round trip over the weekend, had the cruise set at 65 and was very easy on the gas and got 20 mpg.

I get around 13 in the city and 17 on the highway when I drive it like I want to (pretty agressively). If I baby it, I've gotten as high as 18.5 on a 200 mile, all interstate trip at 75 - 80 mph. I could probably get a little better if I had the 5.3, but the little bit of mileage I lose is well worth the extra power and towing capacity. These numbers are with the Edge Evolution on the extreme setting. I'm guessing that my numbers would be better if I put it on a lower setting or put it back to stock.

I am looking at an '08 Silverado 1500 Crew Cab 4X4 with the Max Tow pkg which includes the Vortec Max AFM 6.0L with 4:10 gearing.
There seems to be a huge discrepancy in the MPG numbers given by the dealer (18mpg) for the new 6.0 in a 1500 and people I know that have the 6.0 in 2500's (10mpg). I need both, MPG and tow capacity, not necessarily at the same time though.

So, if you currently have a '07 or '08 1500 with the 6.0L with please reply with the mileage you experience in the real world.

I'm not interested in stories of older 6.0 or 5.3, or the hypermilers... Sorry

Thanks in advance,
Pete

I have the VMax w/HD tow package and 3:73 gears. Driving 70 mph on interstate and around the house for errands etc. I get 15.4 consistently. Went to Columbus on the 4 lanes (not interstate) at 55-60 mph (posted limits) and got 19.6. There will be a difference between 4:10 and 3:73 gears. The 3:73s are plenty for towing as I tow a 33 ft camper that weighs around 9000 lbs. I get around 11 mpg when I tow. The 4:10s will only make your motor turn more rpms and use more gas when not towing, but will help you a little more when you do tow. But not that much...

Hope this helps,
Mike

Just filled up last night, and on the ride from the gas station, to the so's house, to home, I'm averaging 18.3. I've switched my display from the instant econ to the avg, and I think I'll leave it on that and see how well I can maintain that number.
