Is the 6.0ltr really that bad???

[sxmax]

I currently have an 01 Yukon XL with the 8.1 and 4.10s. The wife now wants to get rid of the cars and get a Mini-Van So I think I am going to get rid of the yukon and go back to a truck. The trucks that I am looking at are an 02 & 03 GMC 1500HD CC 4x4 with 6.0ltrs 38K & 66K respectively. Not sure of the gears in the rear. What should I look for and what can I expect for gas mileage? Will either have DIC? Any problems??

 

Thanks!

All your 6.0's will come with a 4.10 rear. The DIC comes with the trucks that have the DIC option. Gas milage should be in the 11-15 Mpg range depending on body style, driving habbits, etc. Also, to answer your header question....there is nothing wrong with the 6.0L, why do you ask? Its a strong engine and should do you fine for just about whatever you need to do.

I just see so many talking about gas mileage. I was hoping the 1500HD I could find one with 3.73's Because this will now be my commuter. Was hoping to find any edge to better gas mileage. Would like a duramax, just can't shallow the price difference.......

Not all 6.0's come with the 4.10...I've got one with the 3.73.....or were you referring to the 1500HD or 2500HD?

 

As for the 6.0, I don't get fantastic mileage but it's a truck and I wanted a truck with power...and the 6.0 doesn't leave me wanted on that. Granted, you'll get more out of the Duramax or even the 8.1 but the 6.0 is a good engine. Just set yourself for 13 or 14 mpg maximum and you won't be disappointed.

you can always change out the gears to 3:73's.. all the people that I know personally that own 6.0l's are getting no better than 11 city/highway. My previous HD had that motor and I could never get better than 10..BUT, that truck was awesome..it was quick and it could pull anything I hooked up to it.

 

Its the 4spd and 4:10's that kill your mileage.. if mileage isn't a factor then you will be very happy with it.

I have an extended cab 2500HD with a 5 speed and 4:10 in it and 275/75R16's on it and when doing mainly highway I get around 15-16mpg. With just straight city driving I get around 12 mpg. I seem to average right around 14 mpg. Once going Vegas to Denver, across Utah with a tail wind going ~75mph I got 19.8 mpg.

You can get 3.73's in 1500HD's. 4.10's are standard only in the 2500HD's. I get 12 mpg with my tryck, tires lift and all. Stock I used to get between 13-14. Not bad for a heavy truck!

[Shaners]

As was already mentioned, on the 1500HD's both 3.73 and 4.10 gears are available. The only motor available is the 6.0L on that truck.

 

Gas milage won't be any worse than the 8.1L you now own. In fact it should be much better. I would expect 10-12 MPG's in town and 16-17 MPG's on the highway.

 

I've seen as high as 16.5 MPG's (one time only) in my 2500HD with the 6.0L and 4.10's. Normally I see 15-16 highway and 10-12 around town. I don't drive with a heavy right foot either.

By the way, the 13 - 14 mpg that I get is using the odometer and gallons of fuel, not the DIC as it can be off by as much as 30%. Remember, mine is a 4x4 so you want to be sure you're comparing apples and apples, not 2x4 vs. 4x4. I also haven't done anything to the truck other than add Westin running boards, spray in bed liner and use Mobil 1 5W30 religiously. No tire size upgrades, no Westers, no air box changes, etc. Granted, 13 - 14 isn't anything to get excited about, but it sure beats towing a boat or snowmachines with a Civic or Prius!!

I myself never understand what the shock and sniviling about fuel milage is always about. NO full size gas powered truck get fuel economy to brag about. Unless you bought a truck to just drive to work everyday because everybody else seems to have one, and now that it doesn't get 30-40m/g your crying the blues. Everytime you tow or load it up it gets the job done right! Then tow it and smile. Just be glad to own a vehicle that has more than the function of hauling only your butt. Just a reality check not an attack on anybody.

I love my 2500hd. The 6.0 is great and strong. The torque management sucks but that will soon be gone for me.

 

Gas mileage isnt the best, but you're moving a truck that weighs almost 6,000lbs. What do you expect? If you want gas mileage, get the minivan. If you want balls, towing power, and one hell of a truck, go with the 6.0 or 8.1 Both are excellent choices.

 

Also, as far as mileage, I actually get only 2-3mpg LESS than my 4.3v6 ZR2 I had. I was always easy on the gas but the truck was underpowered.

My 2004 SLT Crew 4X4 is my second truck with the 6.0. I had a 2002 EC SB with the 6.0 that I used to plow with and I can honestly say that when I bought the new truck I was considering a Duramax. But I sat and thought that besides the price difference(To me it was alot) I could not think of one thing that I DIDN't like about the 6.0. It was and still is very quiet and powerful enough for me. Granted I don't tow a lot , but I do push some serious snow with it and it has never let me down. All I ever did to it was change the oil. It never needed anything else.I think you will be happy with it.

You might want to check the maintance history on both of them. The 6.0 is a great engine for most any situation. You just want to remember that the 02 and 03 were experiencing the csk(engine knock). But by 30k miles it should show itself so check them out beforehand and if ok you should have a great truck with either.

One thing that wasn't pointed out regarding the DIC..I believe this was first offered as an option in the 03 models. If it has steering wheel controls, it should have a DIC..

[sxmax]

Thanks for all your opinons. I am not looking at this thing getting 20MPG. I was OK with the gas mileage of my 8.1 because it was not a daily driver, but If I get this CC it would become my daily driver and i was just wondering about gas mileage for commuting and increased fuel costs. Things are still in the works. We are working on a package trade.

 

Thanks!
