#1 of 27 Need Information about MPG on Chevy Diesel vs Gasoline 2500
Jun 29, 2003 (4:52 pm)
We are shopping for a 2002 truck to pull a 25ft camping trailer and want to know which get better mileage and which is the most economic between Diesel and Gasoline. Looking at Silverado extended Cab C2500.
#2 of 27 Need Information about MPG on Chevy Diesel vs Gasoline 2500

I went from a 454 gas to the duramax and I get 25% to 35% better mileage with the diesel. I have the Crew Cab 4X4 short box and I get 20 to 21.5 empty on the highway and pulling a 10,000 lb. 35 foot trailer at 70pmh I get 10 to 11mpg. There is not a hill on Interstate 81 that I can't pull at 70mph and still get 25% to 35% better millage than I did with the 454 gas and with the gas there are many of those hill 50 to 55 mph was the best I could do.
Buy the Diesel !! For 14,519 on my truck now the overall average mpg is 12.8 and 3/4 of those miles have the trailer attached.
#3 of 27 Get the diesel!!!!

I pull a 28' 5th wheel (about 9,000 pounds wet) plus a boat on occasion. Recently moved from a 2001 Silverado gas to a 2003 Silverado DuraMax diesel. The difference is astounding! Towing mileage is easily 40% better, power/torque on grades is effortless where the gasser struggled, and the Allison transmission is so smart it's almost spooky!
You'll pay more for the diesel, but it's worth every dime!
#4 of 27 Suburbans too?
Aug 19, 2003 (7:58 am)
Does that go for Suburbans too? I'm looking at a very clean '95 Suburban with diesel 6.5 l. I've got a '96 E350 diesel as my work truck, and no experience with GM diesels. Why don't they put them in the Suburban/Tahoe anymore?
#5 of 27 Please

correct me if im wrong, but i remember hearing that they were having a hard time stuffing the Duramax into the Subs and even if they did it would be a detuned motor mated to a 4-speed tranny not the Alison 5-speed. Havent heard anything about it lately, but thats what i have heard in the past.
#6 of 27 95 CHEVY 6.5 TURBO DIESEL
Aug 21, 2003 (2:59 am)
THIS MESSAGE IS FOR BSPARKS. THE CHEVY DIESEL 6.5 IS NOT THE DIESEL TO BUY!!! THIS WAS THE WORST ENGINE EVER MADE WITH MULTIPLE PROBLEMS THAT STILL CANT GET FIXED. THE MAIN PROBLEM IS THE INJECTOR PUMP PROBLEM, THATS ALL YOU NEED TO KNOW, IT DOESNT WORK ALTHOUGH CHEVY TRIED TO EXTEND THE WARRANTY IT STILL DOESNT LAST LONG, TRUST ME I HAD 2 OF THEM SAME YEAR 95 SOLD 1 AND JUST BROUGHT 1 TO THE SHOP LAST WEEK. 495.00 LATER STILL HARD TO START AND STALLS OUT. THAT WAS WITH THE WARRANTY, IMAGINE IF YOU HAVE TO PAY OUT OF POCKET. FORGET IT, I AM GETTING THE NEW DURAMAX ON SATURDAY. SEE HOW THAT GOES. STAY AWAY FROM THE OLD CHEVY DIESEL

Brunopes- thanks very much. That's the kind of info I can't get anywhere else.

Is anyone having problems with the new duramax/Allisons? Also have you heard if they are going to increase the power/torque of the '04 to match the Fords and Dodges?
#9 of 27 I have heard
Aug 21, 2003 (11:34 am)
That GM is putting a variable vane turbocharger in the Duramax staring in mid 04. This is the same type that Ford uses in the new powerstroke.
As far as problems, I have heard horror stories from individual owners of all 3.
If I am not mistaken, the current DMax already has more hp and torque than the Cummins in the Dodge, especially if you but an auto tranny, Dodge has to detune the cummins because they don't yet have an auto tranny to handle 500ft. lbs.
If you are interested in a comparo Pickuptruck.com has an excellent comparison. The new Ford is the clear winner in overall power, with GM second, and Dodge third. In the end however, you need to realize all of these trucks have tons of power, my decision would be based more on reliabilty. In that vane, Ford's engine is brand new as well as the tranny, I would wait 2 years and let them work out the bugs on someone else. GM had to do that with the DMax/Allison, and now they make a great truck. Dodge has a proven reliable engine, (although with recent significant upgrades) but a proven problematic transmission (automatic), in a brand new truck design, again I would wait 2 years on the new truck, and 2 years from whenever they get a better auto tranny.

If you look at the latest specs, for Hp/torque, here is how it is:
Ford = 325/560, Dodge = 305/555, and Chevy 300/520.
Unless you know of an update, this is my latest info on the three. This makes Chevy look kinda bad. Dodge is just barely less powerful than ford. One thing Dodge has going for it is they get theirs at a much lower RPM than the other two.
I pull 9500 5th wheel and looking for the best of the three. Reliability wise, I suspect one is as good as the other, that is after Ford gets their problems fixed.
