Just out of curosity, let's compare a 1500 club cab 4 x4 5.9L to a 2500 club cab 4x4 8.0L. Both trucks will have the auto trans and 3.55 gears. Also, lets say that both trucks are running 265 x 75 x 16 tires. Both trucks have not been modified in any way. Which truck will be quicker and how much better MPG will the 5.9L get (if any)?

I realize the 8.0 has a ton more power than the 5.9 but there is also a large weight factor in there. Anyway, those who know, what do you think?

 

Assuming the V10 doesn't burn it's tires down to the rims while the V8 is actually going somewhere ... the V10 will OWN the V8.

Some V10 owners report similar mileage to that of the 8 ... oddly enough.

Some don't.

 

notice the differance between the 5.2 and 5.9 avg the 5.2 gets 16-18 mpg where the 5.9 gets (for me anyway) 12-16.

i've heard the 10 can get 10-14 if you're light on the throttle and not actually using the power that it has.. and i've heard as low as 6-8. remember the good ole 440's of the 70's? yeah they got 6-8 mpg.

 

I would like to try a V10 sometime. I know my 5.9L has traction issues as well when taking off. I realize the V10 is the more powerful engine, but it is pushing a lot more weight (remember the comparison is between a 1500 vs a 2500 equally equipped). The more you read on the V10 trucks, the more I wonder how they really are. Some people say they are the greatest, some say they ain't! Any more opinions?

 

I've had two 5.2L 1500s and a 2500 V10. The V10 was auto, 2wd and was a handful in the rain; couldn't go anywhere in the snow there was just so much torque right off idle. If I was really careful with the happy peddle it wasn't too much worse on fuel than my 5.2s, but if I was being stupid it would drink hard. The engine never felt like it had to work to move the truck at any speed.

 

I feel I have a solid opinion on this matter as I sold my 99 3500 2WD QC CUmmins last month and bought a 99 QC SB 4X4 V10 2500 Sport. Furthermore my company truck for 3 years was a 99 Ram 2500 2WD SB with a 5.9. I have driven over 300,000 miles in 1999 Dodge Rams, and they all had the same Grey SLT cloth interior, they are pretty familiar to me by now. The 5.9 would get ~14 MPG day to day driving with about 6-700 Lbs of tools and equipment in the bed. Before I bought my own truck I borrowed the company truck to pick up a Grand Cherokee I bought in North Carolina. Pulling a trailer empty I got 12.5 MPG (all highway) and 9 MPG with the Jeep on the back. In the hills of western North Carolina I remember going up a couple of grades at about 45 MPH with my foot to the floor. When I bought my Cummins I put an edge comp box, AFE Magnum and 4" Dynomax exhaust on it got ~18 MPG day to day and 16 MPG towing. Up the same hills in NC with a Beetle on a trailer (The Beetle was obviously lighter, but my new trailer is 1000 Lbs heavier closed deck, winch, etc...) so the weight is about the same I took the grades with the Cruise on at 65-70 MPH, no sweat. My new V-10 has been around 12 MPG day to day, but I seem to put my foot in it more, I like the way it pulls, and its still my new "toy". Pulling a 1953 Plymouth Station Wagon last weekend I got 10 MPG, only went to Michigan this time, so no comparisons in the hills. One thing I did notice is the Cummins would hardly ever downshift with the cruse set at 65-70 MPH towing, where the V-10 does occasionally, it never dropped back like the 5.9 did, just needs to stay in the powerband. No trailer, driving around town, the V-10 will easily out run both of the other trucks. I am looking forward to see what Improvements I get in Milage and performance, as Just today installed a Gibson Cat back exhaust on it and hallowed out the Cats, as they were bad and rattling anyway. This combined with the FIPK I installed last week have seemed to help wake up the V-10 quite nicely. Next plans are for a TB, and lastly a set of headers. I am very happy with the V-10 compared to the Cummins. It burns more Fuel, but Gas is ~.50-.60 cents a gallon cheaper here in Chicago, and Its soo quiet, even with the Exhaust and intake compared to the Cummins. The Cummins I had was a "53" block and I always worried about it cracking or the Injector pump failing, they are not cheap to repair. Now all I have to worrie about cracking Cylinder heads and detonation

 

I have to argue with these statements unless you are talking about 2wd standard cab...I have documented every mile that I have put on my truck(5.2, 4x4 QC)and every drop of gas that has gone into it and my MPG only equates to 12.8-12.9 with the occassional high of 14.? and a few lows down to 11.6. It doesn't matter what I do, that's what I get.

My dad also has the 8.0 and has never gotten better than 8.5-9 MPG.

 

I got around 17.2 mpg on a trip a couple of weeks ago. Mine is a 5.9L ,4x4 QC . It gets around 13-14 mpg around town on average. Everything is stock for now.

 

my v10 gets about 12.4 all the time and when running right, the pweor versus the 5.9 is tremendous. if you plan on pulling heavy stuff the v10 or cummins is the way to go. many opinions to be had. dive a v10 ifyou like but it.they rally are great GAS powered workhorses.

(bye the v10 comes with 4.10s i believe, least mine did)

juswt go test drive one, you will see/FEEL the power difference.

then if you can try all three towing. (if you do that sort of thing.)

 

I don't tow, but I do love torque!! I couldn't afford a V10 anyway, they usually run about 2 grand more than a equally 360 equipped 1500. Not to mention the added gas costs.
