8.1 vs 6.0


Recommended Posts

Posted

I'm looking to get a new 2500 Suburban.  I will use it mainly as a daily driver, but sometimes for some light towing/hauling (e.g., a couple of dirt bikes on a small open utility trailer).

 

I am debating between getting the 8.1L and the 6.0L.  Because my towing is so light (my wife's current 1500 5.3L 'burban can handle it no problem), I want to get the best daily driver.  Is the 8.1 much faster than the 6.0 (the 8.1 has much more torque, but not much more HP)?  How bad will my MPG be (unloaded) if I get the 8.1?  What would the MPG be on the 6.0?  Does the extra weight of the 8.1 cause any problems?

 

(I'm a newbie, but this looks like a great board)

 

Thanks for any thoughts.

The 6.0 sounds perfect for what you are going to use it for. The milage on the 8.1 is around 10-12mpg so for a daily driver it is not the best. Hp does not mean a thing in a truck, it is all about the torque. The 8.1 has 455tq and the 6.0 has 360tq, but there is no need for the 8.1 unless you tow 10,000lbs. The 6.0 also has more than enough power to move the 'burban with no complaints. BTW, welcome to the board :cool:

I agree that the 6.0L would be a good choice for a driver and light tow vehicle.  In fact you really don't need the 3/4 ton unless you just really want one.

 

In the 2500 series Avalanches and Suburbans, the 8.1L is restricted through a "torque management program" in the computer.  The computer won't allow all the HP and torque of the 8.1L to be released until the truck is rolling.  Once the truck is rolling it will pull like a "raped ape"...

 

The 6.0L will certainly give a little better gas milage...

you will go through alot less oil with the 6.0 as well.  I pull 2 500lb sleds on a 1000lb sledbed trailer with my 6.0 and dont even notice the weight. :cool:  :thumb:

    • New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended? 
    • So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.  
    • Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.
    • That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
