Chevy/GM 6.0L Gas?

What's the word on these trucks and motors, specifically the 04-06 models?  I've seen some pretty decent deals on 2500HD's with the 6.0's in them.  A friend of mine had an 05, seemed to me that he got right around 14 mpg at best highway?  I know the 6.0's are gas hogs, but people seem to really like their towing ability.  Any thoughts here?  I'd be curious to hear what guys who have had them have to say.  Any issues, etc?

Hey trax~

Good engine and tranny,2003-2005 1 outof 10 had lifter noise (actually cyclinder slap) when cold starting but know worries,the same powertrain from 2007 and up have a 5yr/100k warrenty.

One other thing is the secondary steering shaft,take her for a spin and turn a few corners,you might feel a raddle,its an easy fix and most dealers have "good will'd " the fix @ n/c on trucks under 100k,but your area might be different,just a headsup.

I had an 03 Chev 3/4 6 liter and I loved it.
I traded it because I did not think I would be
pulling a camper anymore but found out
later that was very wrong.  I've been running
Chevy 1/2 tons with the 5.3 liter but they
are a little to light for pulling a heavy camper.
I went to a crew cab 4 door, but I hate the
small box, it's a real pain.

Funny you should mention because I just
traded again on a 09 3/4 6 liter with a 6
speed auto trany. Price was very right!

We have 5 of the 6 litres in our workfleet and for the 3 years I've been there they have been great trucks.  Snow plows on them in the winter and lot's of towing year around.  Like was mentioned above my only complaint is they are really 'THIRSTY".

I have an 2001 chevy with a 6.0 and I love it, good power, make around 15 hwy, always starts in the cold, loves to run at higher rpms, I was told the piston slap is normal and that the top end of the engines are built like the engines for race cars once everything warms up the noise goes away.
I am excited to get my hands on the 6.2ltr and see if there is any difference, I think its bigger gas engine you can get then with a ford or dodge I believe.

be careful pressure washing these engines.  moisture gets in the knock sensors and ruins them.

I have a 01 5.3 in a half ton.  I hear rattling and knocking when she is cold but goes away when it warms up.  It has been doing it for quite some time.  I have almost got a 150,000 miles on er and it has been a great truck.  My buddy has the same truck and he has almost 400,000 miles on it with no major problems.

Had a 2000 chevy 2500. Great towing power but the gas mileage abosolutly sucked.

I joined the military not only to fight for my country but to fight for those that can't fight for themselves. Thats why I'm here.

Traded in my 01 1500 on a 04 Yukon XL Denali last summer.  Was pretty anxious to see what kind of milage I would get with the 6.0 and AWD.   Pulled 16-17 this summer and averaging around 13 this winter so I'm pretty pleased.  Cold snaps usually worse as idle time to warm up I increase quite a bit.

I have an 01 with 100,000 trouble free miles.  I run this truck like I'm in a BAJA race every time I take to the hills, can't seem to break it.  I would purchase another in a heartbeat.  Decent towing power for a gasser, gets 10.5 mpg towing and 13.0 otherwise.  The piston slap is from a skirtless piston design in 01 and 02.  I believe they went back to a skirted piston in 03.

My personal opinion.  Get the most heavy duty pickup you can afford.  The gas mileage isn't going to be a big enough difference between a 1500 half a 1500 HD or the 2500.  Maybe when you get up to the 2500 HD it will but I'm here to say that driving my 2006 it gets hardly any worse than my buddies regular 1500.

Even if you want to pinch pennies.  The saving in your fuel is going to pale in comparison to the loss in power and ability to handle loads.  Big GIANT difference in both my uncle and my opinions on the 1500 HD he sold me to the new regular half he purchased brand new.  The HD is just so much more comfortable with ANY type of load to it.

I will most likely never own a regular 1500 again as long as I will be hooking onto boats, campers, snowmobile trailers, etc.

Now as far as fuel.

My uncle put about 27,000 miles on the pickup before I bought it.  He never ONCE changed the fuel economy.  For the life of those 27,000 miles he averaged 12.2 miles per gallon.

I have done much more eye watching on it.  On the highway with no load and no wind I can get 16 to even 17 mpg at 65 mph.  Now, if there is a wind or I bump it up to 70 I'll get around 14.5 mpg.  The minute I hook up to a boat or work it hard I'm going to be down to 10 to 12.  In town, well, it just pure stinks.  Usually around 10 and lower.  So, if you punch all those numbers together and stuff is pretty much a lock that over the life of the pickup I'll get around 12 mpg.

Was hooked up to a non-aluminum 4 place snowmobile trailer with three snowmobiles and two portable ice houses and averaged 9 to 11 miles per gallon.  9 was when I was putting the screws to it via hills or something.

My buddies regular 1500 half crew gets really nothing better than my 1500 HD.  He said over the weekend he'll never not get the at least a 1500HD.  Just some food for thought.

Tim, I assume you've got the 6.0 in that 1500HD?  One of our company trucks is an 03 1500 HD, but I seldom spend time in it.  Seems solid.  I checked today and the fuel mileage calculator says 11.5 mpg, all in town driving. 

My current 1500 needs replaced.  The 5.3 is fine really, and I can get 17 or so if I drive nicely on the highway, 14-15 in the city.  The 6.0's, at least the earlier ones, seem to get 14-15 at best.  In town 10 to 11.  Average of about 12.  Not a huge difference I guess. 

I too like the HD series.  More truck than std. for sure.

For the mileage I drive, the difference between the 5.3 and 6.0 mileage probably isn't substantial.  I'll put about 10,000 mi a year on, maybe less.  The added towing capability of the 6.0 would be welcome too, I seem to be spending more and more time pulling the boat or decoy trailer.

Now I dont know how much stock to put in to this but I have been told that the 6 liters in the Denalis etc for some reason get better mileage than those motors in the HD's
Had the word detuned used on me as to why the difference .

I average about 14-15 in the summer on a Denali , less in winter , very  good power ,
never had a problem of any sort

6.0 (Chev)or V10 (Ford/Dodge) is going to be my next purhase; unless I can find a sweet deal on a gently used and low priced diesel---not likely.  

My 97 Ford 1/2 ton with a 4.6 5 speed has the pedal to the floor when pulling my boat and gets, AT BEST, 10 mpg with 7.5-8.5 the norm...  That is from Fargo to Devils which is a pretty flat pull.

2 buddies with 6.0 Chevys; 1 with the 1500HD and the other has the 2500 have been very happy.  The 1500 gets up to 15 on the perfect day, the 2500 gets 12.5 at best, but they both get 11 pulling ANYTHING..

YES, I am that foolish!

Trax,

Yes, it is the 6.0.

Been happy with the pickup.  Ride is a tad rough but jeepers, I can't have everything!  One thing I am somewhat concerned with even though I don't see a 5th wheel in my future for quite some time is I don't know if the 1500 HD is enough.  I'm guessing a guy would be much happier with the 2500.  I had a little squat to her when I was hauling the ice fishing gear last weekend.

I contemplated chipping out the pickup.  Was going to but spent the 300-400 elsewhere.  Still might, especially if fuel prices explode again.  It doesn't help you tremendously but if you drive enough the couple extra gallons per mile quickly add up when spending 3 plus per gallon of fuel.

Also, I didn't see a huge difference in fuel differences.  Dad did get the best with the pickup at 17 mpg when he filled with premium.  I'll do more studies on that this summer.

54,Not the same engine,the denalli has the high out engine,more Hp where the HD 6lit has more torq~ and less Hp,a stump puller if you will.

Timmer's~

Does'nt your 1500HD have 3.73 gears? rather than 4.10's...less rpm's= better mpg's.Just about every HD truck out there will average 12mpg's prior to 2007 when power changes were made (new body style GMT 900)

I just bought a half-ton with the new 6.0 vmax which is a different motor(L76), than the 3/4 ton 6.0, and the earlier 1500 hd's. so far i haven't really pulled anything for mileage that way but  with the AFM, which cuts it to 4 cylinders down hills, flat terrain going 55,etc, i get right around 17, i drove from bis to beulah and back which was 78 on interstate 65 on 49, and 55 on the gravel had a wind against me on the way there and no wind on the way back, the average was 16.6 that was using the auto start(runs for 10 minutes) twice, and cruise control on everywhere except the gravel. My 5.3 which i had exhaust, cold air intake, and a hypertech programmer on the similar route was getting about 17-18, summer driving nice was close to 19.5mpg. A buddy at work has an 1500HD and he gets 12-14, 4.10 gears i think, another guy has a 05 1500 hd gets around 14 pretty religously 3.73. both guys love the trucks and when they pull they are glad for the extra torque the 6.0 has over the 5.3. I liked the half ton better because i still have the Auto option for the transfer case, have 367 hp 375 ft/lbs, no stabilitrak, and half-ton ride, but it has the MAX suspension which is not as stiff or have the springs the 3/4tons have for towing but is a little beefier than the regular or z71.

this is a pretty good site for the silverado, http://en.wikipedia.org/wiki/Chevrolet_Silverado

on a side note i have a hypertech III programmer and K&N cold air intake for sale for a 2000 truck the programmer is for all 2000 model v-8 truck motors, while the K&N should fit most 5.3 99-07
