#3 of 1057 8.1 Information by woolyback2 Nov 26, 2000 (6:27 pm)
Seeing as we are switching to a new section for the New Sierra/Silverado 2500 & 3500 Topic I would like to take this opportunity ask all new purchasers of the 8.1 for their input. I would like to find out what your towing experience is and mpg or anything else that you think would be of interest to a potential buyer. Any problems with the SES light ?? All information would be appreciated, thanks.

My business just bought one that my partner will drive.He picked it up on Tuesday. I drove from his house to the service station for new tires. It only had 20 miles on it and I was driving through a housing development. It feels real good! I drive a 00 2500 and the HD is a lot different. I'm sure the 4:10 rear end has a little to do with that. It feels like a lot of power. If you like power I don't think the little bit of difference in gas mileage will make much difference. I can't wait to drive it when it's got some miles on it. That is if let me [turn it loose]. Billy

I ordered mine from Huffines for $500.00 over. I placed the order with the dealer on Aug 02. It seems the 8.1 was on constraint for a long time. I now have a build date of Dec 04. GM tells me it may be here before Christmas. The Power Tour was in my area about two weeks ago and one of the guys that does the driving said the 8.1 was getting between 9 and 10 towing one of the large trailers. He also said the DMAX was getting 15 towing the same type of trailer. The Power Tour is geared for selling the DMAX. I cannot see paying that much extra for the diesel and the only reason I ordered the 8.1 is so I could get the Allison trans.

In response to #563, my surburban has a bad "reverberation" when running at highway speeds with the back windows down. In fact, it's so bad it will run you out of the truck. So, needless to say, we keep the back windows up when on the highway. The kids don't appreciate that, but my ears can't take the pounding. I'm one of the 2 guys in here who prefer the manual transmission and after reading about the guy who wore out 3 automatics towing with ford's and gm's, I plan on staying with that attitude. I'm sure the allison is a better transmission, but at 2,000 bucks, it better be. I just don't won't to be the one to pay all that money to find out. Bud

#10 of 1057 MPG's... by 4x4 Nov 27, 2000 (12:03 am)
I would really like to see someone's 8.1L MPG's...everyone keeps saying the mileage will not be too much different than the 6.0..I just don't see it..365CU VS 496CU..I have gotten 14 on highway and 12 city..4Wheeler Mag tested the DMAX and 8.1L and there mileage reports for mixed driving was 15.8-DMAX and 9.1MPG for 8.1..unloaded ext cab 4x4's.. I could see maybe the 8.1 getting better MPG's if the 6.0 needed to work harder to push the truck but i don't see that at all..Honestly, I feel the 6.0 has a lot of power and hauls butt...again if i towed a lot i would get the 8.1/allison combo but the most i tow is a 22 ft bay boat... anyway , I would like to see some REAL LIFE numbers from someone with 8.1 and 4.10...
#11 of 1057 auto vs manual by tnglator Nov 27, 2000 (1:46 am)
I ordered a 2500 HD with a HD NVG manual tranny. Did I make a mistake? I wont be towing an incredible amount at least not for now. Has anybody ever driven the manual, how does it feel? I would appreciate some input while there is still time to change my order if I want to. Mileage i figure would be around the same since fourth in the auto and 5th in the manual are the same and I do alot of freeway driving....please help me out with this decision...
