2008 dodge ram 2500 q. cab cummins



Someone should call this guy and ask him how he achieves this!

 

[JohnBoy5]

lol maybe its a VW diesel in a costume.....

 

[domehead]

Is that going down hill with a tail wind LOL right someone has been smoking something

 

[JohnBoy5]

yea a 100 mph tail wind pushing the truck. lol i didnt know you could smoke anything that good to come up with a number like that. LOL

 

[Simplysmn]

awwwwwww COME ON GUY'S HE THOUGHT it was a power Joke:-laf:-laf:-laf:-laf:-laf

 

[AWeiman]

ya he is lying about being a non smoker thats for sure. what is really sad is someone will buy that expecting to get over 900 miles on a tank of fuel.

 

[icman95]

I think it's just an honest mistake. He simply misplaced the decimal point. Should have been 2. 7

 

[Wingate]

Thats funny...

It can be done. I have the same vehicle. I was stationed at Fort Huachuca AZ, Sierra Vista AZ 2008-2009. I ran Route 90 North towards Benson AZ to the intersection of I-10 and 90 and headed West on I-10 to Tucson AZ. Total trip was less than an hour... but I was experimenting at speeds of 50 MPH. That was not only scary but stupid as I almost got my butt run over on I-10 where the speed limit is 75 but everybody is running 80+. ANYWAY when I got to Tucson I looked at the overhead mpg/avg it said 26 mpg/avg. Now I did not check it against fuel-vs-mileage using a calculator..... but... if you hold your speed down, have an empty truck... you can possibly achieve this. I am now in the hills of Pennsylvania and I can still get 25 mpg on the overhead driving from Volant, PA to Erie PA on I-79 . . again doing only 50 mpg. My average in the city is around 18 mpg. Nuff said.

 

[JohnBoy5]

hmmm IDK, was that hooked to a tow truck.....

Do you really believe in the overhead dummy light?? I'd suggest that you do some old fashion arithmetic.

 

[SNGLESHOT]

Just using the overhead "dummy" light as a trending point. If you read my post I did elude to the fact that I did not calculate by hand. I have since done so and my calculations do come out a little less than the overhead but not much at all, in fact less than one mpg. I was only trying to press the point that this person selling his truck may be telling the truth as HE sees it. Im not lying about my numbers either as I have no reason to do so. I am done with this post. You guys can go back to ridiculing someone you don't know again.

Please give us more information about your truck and what type of driving highway, city, flat, hills etc. Any mods on your truck etc. The reason I am asking is I have not been able to get over 16 with my 2010 and 18 mpg with my 1998 2500 etc. and I think most dodge owners have below 20 mpg.



So we need to know how you are making that type of fuel mileage.



Thank you for your feed back

My '94 did an honest to god 27mpg one time on a 200 mile trip. I was driving 55mph, empty. Truck was pretty modified, different injectors, turbo, straight pipe, cam plate, electric fan clutch. What gave me the fuel mileage was a US Gear overdrive. 55mph the motor was only turning like 1200 rpm. The electric fan clutch made a pretty good difference as well, still quite a bit of drag with a viscous fan clutch even when not engaged. I generally drove it 75mph and usually averaged 21-23mpg. All hand calculated (not even sure if it had a DIC back then)

Domehead (me too), I thought I pretty much explained it in my first reply post as to the location, area, distance, and speed of my truck, etc. My signature states no mods but here it is:

It is pretty flat in Arizona for sure and the rolling hills you climb are very gradual. As for Pennsylvania, it is very hilly, rolling and otherwise. Both times I was on an Interstate highways and both times doing 50 mph. My truck is 100% stock off the lot with no modifications at all. It currently has 49,000 miles and the only problems I have ever had was with the DPF and the recall flashes fixed that problem. I currently use it consistently between home and work, with combined city and country, 2 lane, red lights, and hills. I still average around 18 doing that. This is with the truck being empty except for tools and some stuff in the back seat. I think it is really all about how you drive. Keeping your speed down below 50 if possible. Stopping and starting easy if possible. I don't lug my truck even if it wants to (and it will) ... I choose a lower gear to keep rpms up around 1500 at least. I don't let my truck idle. I don't let it warm up either, I just make sure I have good oil pressure and take it easy for the first few miles. In the winter I use the block heater and that helps some i would guess. I use my exhaust brake ALL the time except for during icy snow or rain conditions. Not sure if that has anything to do with it. I buy my fuel from same place that has high volume turnover and I change my fuel filter every 15,000 miles too... just in case.

One thing my friend Harvey B. told me a year or two ago when I was brand new first time diesel owner... . "it takes some time and miles to break these beautiful engines in ya know". Personally I think mine is STILL breaking in. :-laf These engines love to work hard. Don't be afraid to hook up to heavy load and mash that pedal to the metal. Its the 'grocery getter' crowd that is usually having all the problems. I pulled my camper from PA to AZ approx 2200 miles and averaged 13. 4 mpg on overhead. That was heading west and my truck was brand new right off the lot too. I did better coming home to PA because I didnt have to fight headwinds heading east as much as I did heading west- 14 mpg. My truck and camper weighed 18,746# combined total with me in it . I weighed the whole outfit on a truck scale at flying J truck stop. The truck bed was full of stuff and the camper itself was quite full.
Well that is all I can think of. Long story. If you want more specifics not sure what else I can offer you. These are beautiful machines and they will work their hearts out for you with just some good maintenance habits and common sense driving habits. They will last you a lifetime. Enjoy!

Sngleshot,



Intersting I just did around trip to Disney in Fl towing a trailer with a small car on it total weight of trailer and car aprroximently 8,500 pounds. hand calc. the mpg and it was 10 going down and 11 coming back. Yes I was traveling at the post speed limit otherwise on I-95 you willl be road kill. Even with the truck empty the best I can get out of it is 16. 5 thats going down hill.



It appears that you have one of the better trucks for MPG.



I use my truck as work truck and I do load it down.

 

[SNGLESHOT]

I understand about getting run over. It is risky. As I stated before on I-10 between Benson AZ and Tucson... everybody is doing 80+ mph and you turn into a moving roadblock. The cops there don't like that at all... jams everything up. However, the day I did my 50mph test run there was hardly any traffic at all. I have no answer as to my MPG ratings other than the way I drive and the consistency of what I do when I am driving... . it all I can think of right now. If something comes to light, I will post it here or message you directly. Stay safe and enjoy that beautiful machine.

10mpg pulling a small car on a flatbed?? Wow!

 

[SNGLESHOT]

Domehead, PS from my last post:
I still think part of your situation is the motor needs broken in a little more... . it will loosen up for you and then your mileage may increase. When I was pulling my camper cross country that time, I stayed with traffic flow pretty much and didnt experiment with slow speeds, etc. mpg avg fluctuated greatly during the trip but the overall average was 13. 8 and 14 mpg with the camper. Headwinds will definetly make a difference overall too. Take care.

 

[domehead]

10 MPG is going through rolling hills and traveling at 70 mph. The truck has the 3. 73 gears, plus a manaul and is a 4x4 which will decrease over all mpg. As of todate it has 15,000 on it and by the end of the year it will most likely be close to 25,000.
