I've pulled 16.8 and 16.9 MPG in mixed driving on my last 2 fillups. The abuse management really holds this engine back. Going WOT @ 40 mph will put you back in the seat. Stock exhaust sounds almost perfect.

I pulled an 8 foot trailer full of sand bags plus a box full of sand bags with my 6.2 gas mileage stayed basically the same at about 14.8-15 there was definitely less power but having a box full of sand bags is a lot of weight I should have tried it with just the trailer but still there wasn't a tremendous loss of power I love my 6.2

Just got back from a weekend camping trip. My Camper weights about 7500 to 8000K loaded. I got on average for the trip 9.3 mpg on the 330 mile round trip across Pa. And Pa has some mountains to climb especially on Rt 6 which runs across the top of the state. Power...well no problem there. That 6.2 with 3:72 rear, K&N CAI and BB tune is absolutely amazing........Not towing, realistic numbers are 17 to 18 highway (my best is 18.6) and 14.8 to 15.2 in town. Thats driving sensibly.

I've had my 6.2 since '06. I do have the Denali (AWD). One of the best vehicles I've driven so far. It's a damn shame it's consuming oil and has excessive piston slap.

 

I didn't realize the 07 Denali trucks had the 6.2L. I'm thinking about buying a Sierra with the 6.2L. Care to elaborate about your troubles? Anyone else having these issues?

Hi, guys. This is a very interesting and informative thread for me.

 

I have a 2008 Silverado Crewcab 4x4 Vortec Max and the performance of this truck is awful at best. We are planning to get a new trailer/5th and will be in the 6000-7000# (dry) and 600-1000# hitch weight range. This truck is frustrating to drive and there's no way I'll consider pulling anything with it. It does have good power once you get going and the computer allows full fuel delivery to the engine but based on the poor driveability empty I can't imagine having 6000# + behind it. In my opinion, a 5.3/6-speed auto performs better than this truck.

 

The size range of the trailer seems like perfect match for a Sierra 1500 Extended Cab Max Tow 4x4. I was considering an Ecoboost/6.2 F150 but eliminated them. The Sierra extended cab would give lightweight 5th capability even if I don't end up needing it. We aren't millionaires but we will spend the money on the proper vehicle in order to not be dissapointed.

 

I think the Max Tow Sierra will be fine and will cost a lot less then even a 6.0HD in similar configuration. I don't plan to tow to it's maximum ratings, maybe up to 75-80% towing and payload. On paper, this truck is perfect IMHO and I won't be overloading it based on what we're planning. The 1500 is easier to park, lower to the ground for less drag and easier to use than a HD in general. I'm not concerned about having the biggest, tallest truck. We're just trying to find the best bang for the buck.

 

I don't care about mileage. The amount it will be used will never make up for the cost of a diesel.

 

You've already answered a lot of questions I had so thanks! :rollin: I do have a few questions, though...

 

1. How well does this truck handle the weight? Is it stable in all conditions ie. wind, crosswind, bumps, rough roads etc.

 

2. How is the braking? Does tow/haul downshift on it's to help keep things under control? Anything scary going downhill?

 

3. I know the power is there but can it truly hang on the hills with 8000# or more without making it scream?

 

4. Does the truck hold gears well under load? No constant shifting?

 

Outside of this, I have a company truck so the Sierra would spend a lot of time sitting in the garage. It's sole purpose is pretty much for towing the trailer and the odd general use. It might see 10,000km's per year (6,000miles). The truck we buy will last a LONG time so I wanna get it right lol

 

Any input beyond this list is welcome, too. Thanks in advance for any info! :mad:

You must have a bad Vmax. I had an 07 4-speed with 4.10 gears and I felt it handled the weight very well. Although I had mine tuned but thats not alot when it comes to towing. I've towed many times close to 8000lbs without issue and distance too. That being said, the new 6.2L 6-speed with 3.73 gears is nothing short of awesome in my opinion. The only thing I've towed so far has been a small trailer and a 3000 lb car. Both loads, the truck hardly knew it was there. Braking on the 2011 is MUCH better than the 2007 I had.

 

As far as your questions go, I'm not much help but I assure you, it would/will run circles around your current Vmax. :mad:

It might be a bad truck but I have 3.73's and 20"ers. That could have a lot to do with it. The throttle control is really intrusive, I assume it's a way to help reduce warranty claims on the extended driveline warranty. When it powers up it has balls, no doubt. I'm looking forward to see how knarly a 6-speed/3.73/17" wheel truck moves with a bunch of extra power on tap lol.

 

Braking is a big deal, thanks for the info. Mountains and braking go hand in hand!

I'm running 20" wheels and did on the Vmax as well. The throttle delay is TERRIBLE for the Vmax. The Custom tune REALLY helped that. The 6.2L does not suffer from the throttle delay. It will roast the tires on demand. No lack of power or throttle control.

 

It's night and day over the Vmax.

I have a Predator on the truck and it helps but I just got tired of the driveability issues. I barely use it but it is a beautiful truck. I've had good luck with GM's.

 

I gotta admit the 6.2 would be fun as a sleeper. I think it'll also pull well with no drama. I'd like one with the two-tone interior in black. These trucks aren't exactly common and my guess is I'll have to order one. I'm not settling for something close. It'll have to be exact.

I had to order mine. I looked for more than 6months to find exactly what I wanted and it wasn't out there. :rollin: As for the Vmax, the diablo had no TQ management controls and still lacked in programming. I had one too. It was ok, but when I got the Blackbear tune for it... it was again a very different driving truck with the custom tune.

 

I got the 6.2L tuned as well :cheers: It rips :mad:

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.

      Weird click noise when revving my truck?

      By JimmyB4 · Posted

      Hello Guys I'm new to the form,         I just put a 7-inch Rough Country lift on my 2016 GMC Sierra 1500 with the 5.3 and I also put a Borla exhaust on it. But I noticed when I'm in park or in neutral and then I rev my truck up really quick there is a bad click noise and I think it's coming from the motor somewhere. Anyways I got a video of it I will attach below I was just wondering if you guys think its rod knock or lifter tick or something like that because I know the AFM kind of made the lifters weak on these trucks.       Thanks!!!!!

      OCI, not when but why?

      By KARNUT · Posted

      We’ll have to agree to disagree. I didn’t experience or know anyone who had a decent car after 100K miles in the 60s through the 80s that were daily commuter vehicles. Unless they were collector vehicles. Of course things cost more due to inflation. But we also make more money. The biggest money drains these days are things people think they need today versus what we require back in the day. Like cell phones and internet as examples. Another example is where you live. Cost of living varies from state to state. I would need twice the money to live in NJ vs Texas in retirement. The car you recently purchased was less than my first car with inflation at 3000$ in 1973. I didn’t have air, electric windows, cruise etc. Purchasing power is equivalent, you just have to do the research.

      Trim level custom/pro

      By newdude · Posted

      Sierra HD Pro:   - If you want a power driver's seat on the Pro, you can't get it.  You have to go to SLE.   - Factory remote start?  Can't get it on any of the Sierra Pro trim (1500 or HD).  You have to go SLE.     - 7 inch radio has limitations for replacement if you wanted to upgrade the screen, etc.    - Steering wheel radio controls?  Nope.  Can you add them?  Yes.  NOT CHEAP.  Requires a new instrument cluster, steering wheel and wiring harness mod kit.     - Fog lights?  Nope.  And no factory path to install them.    Sierra HD SLE:   - IMO, the larger radio screen is a much better interface.   - Fog lights?  You can get them.  Steering wheel controls?  Has them.  Remote start?  Yep.  Power driver seat?  Available.       Silverado WT:   - Same as the Pro above however you CAN get factory remote start installed at the dealer for the WT Chevy.     Silverado Custom:   - Comes with 20" wheels only.  Can you swap later?  Sure.  But.  Truck is calibrated for the stock 20s (34" tire) and no path to properly recalibrate.     - Power seat?  Yes.   - Steering wheel controls?  Same as the Pro above.  No but can be done and not cheap.     Silverado LT:   - Same as the SLE.  You can get or it comes with many features you can't do on the lower trims.       I'd say its all going to come down to what you NEED and what you WANT to have that you'd benefit from.  For me, things like power seat is a must (I hate the WT/Pro seating position), so I'd have to go Custom, LT or SLE right out of the gate.  Steering wheel controls?  Should be standard in 2026 across the board IMO, so again, puts me to LT or SLE.

      Trim level custom/pro

      By Coastie05 · Posted

      I have a 1500 but the Custom trim. I bought it solely for the simplicity meaning less electronics. I also love the old school gauges. The only thing that I like about the LT better than my Custom is the front grill. Otherwise, absolutely no regrets choosing this trim.
