RAM V10 mileage-Any way to improve MPG?
« on: April 17, 2006, 02:53:10 PM »
Greetings all...new member...new to Dodge Trucks.

I recently purchased a 99 Ram 2500 V10 (yeah I know...$3.00 a gallon...bad timing on THIS purchase!!) and apart from the usual steering problems you've all covered in excellent detail here, I'm wondering if I can improve the mileage to better than the 7.5 I'm getting now.

It doesn't have stock width tires so I know that getting rid of them will improve mileage but are there any tips n tricks anyone knows of? 
I installed Bosch 4 platinums but I can't say as I like them very much. I lost 1/2 a gallon in mileage with them compared to the OEM Champions and need to get them out of it yet. Filters are all new.

Will going with a limited slip diff and getting rid of the locked posi pumpkin at the rear diff do anything for mpg (and possibly helping get rid of the bunny hopping around corners at low speeds)

I was thinking about yanking out the V10 and trying to shoehorn a hemi in there...is there any reason other than the need to change electronics why that wouldn't work?

OK..that's enough for now from the newbie.   ::)

I love the truck but I only wish it would pass gas stations as well as it passes everything else on the road.

 Thanks! I'll be looking forward to your replies!

Attempting to swap a hemi into that rig opens a whole can o' worms.  Besides the electronics, you would also need a tranny, and Tcase if it is a 4x4.  I am not saying it cannot be done, but it would be a loooong time before you paid off teh cost of converting with fuel mileage savings.

My old man managed 8.5-9 mpg around town with his '01 V10 4x4.  The only modifications were true 3" duals and a K&N drop in.

Every time I drove the beast I got comparable mileage to you, 7-7.5.  A light foot may be about all you can do. :-\  That is 488 cubes of fuel thirsty beast....

whiner
that's not much worse than my worn out 318, and it has no power to go with the sucky gas mileage.

Anyways, as suggested a better flowing exhaust and intake could help some.  Even if only 1 mpg improvement, it won't take too long to make the cost back up at almost $3 per gallon.
Skinnier highway tread tires, at max pressure, could help as you mentioned.  And of course, going easy on the skinny pedal.
If it's feeling rather strong off the line, and you wouldn't mind loosing a bit of giddy-up there, going to higher gearing will help too.
Can't see a limited-slip doing anything for mileage.

There's another thread going somewhere (Vehicle Help, Technical, or Open boards.  Can't remember which) with an arguement over tailgate down, full bed cover (hard toneau) or full topper.  may find it and see if any of the theories there interest you too.

Thanks guys. Great site! I'm enjoying it.
That's the kind of reply I was looking for...no BS just the Fax. Scrap the hemi idea. The truck has to be a daily driver so can't be down for a month or more to make the conversion. Looks like it's down to skinny tires and gear changes.

Yeah, in retrospect it wasn't the best purchase I've ever made. I got giddy when the kids all grew up and moved out and just wanted a toy. At my age it's either toys or chucking it all for a shiny red Corvette and a 19 yo blonde (or is that blonde 'Vette and shiny redhead..I get confused)   ;D....
I think I would have gotten better mileage from the 'Vette and the blonde..and that's including the cost of Viagra.    ::) ;D

Thanks again. I have some forum searching to do for tranny repairs for the beast in question.

Assuming its a factory set-up and not an open diff, than it is a limited slip. It wouldn't have a locker unless the previous owner installed it. Also, "posi" is GM's name for a limited slip, it's the same thing.  ;)

Regardless of what is in your diff now, changing it will not affect mileage.

The width of your tires won't adversly affect your mpg either, taller tires will affect it much more.  You could try going with a slightly taller tire and see if your mileage improves on the highway.

Wider tires = greater rolling resistance (i.e. friction) which can lead to worse fuel economy.  But I do agree the diameter of the tire has a more significant effect.

...and the additional weight of a wider tire takes more energy to get rolling.

  The tires weight,  and a rear with a tight diff that makes the rear jump in turns or binding WILL effect your mileage quite a bit,  any binding in the drivetrain will effect mileage.

I assume the "bunny hop" he explains is the normal give and grab that a LS will do on a corner while giving a little throttle when there is a bit a loose gravel or dirt on the pavement .
Unless a person drives around corners all day, it won't affect mileage.

      That isn't true....you do realize if one tire is at 38 and the other is at 33 it will make a difference and there will be some binding... That means you don't need a turn to bring on added force and most roads have turns in them,  and slight turns in them then they are straight for any period of time.
   If such a thing was true then the syn oil in the driveline wouldn't make a difference either...everything adds up and you might not think it is enough,  but it's enough to add to mpg decreases,  running syn everywhere and over inflating the tires and lighter wheels and lighter driveline parts will always help mpg and power increases... just turning 1 tire rather then both in an open diff will make a difference...

Well that's interesting.  ::)
I haven't noticed a mileage decrease since I put my locker in (read, way more "give and grab" than a LS)  ::)

Of course I've checked, or I wouldn't have made a claim.

If he is talking about the same bucking that I get with my LS in my 2000, this is only on the tightest corners. There is no "bind" otherwise.

over inflated tires, syn oil, light wheels.

These things have nothing to do with the subject. If a LS is going to affect mileage (which I say it won't), it would do it regarless of the PSI of tires, type of oil or weight of wheels.

     A diff that powers both wheels will be affected by air psi in the tires not being equal it will have steering effects,  nothing hardcore, but it will have steering effects as in drag...if you can't notice it then there are all kinds of slop in the driveline absorbing it..further effecting mpg..which would be something that is highly possible

I can't speak for the original poster, but my tires psi is always the equal in the rear, I would not assume his is otherwise.

As much as I hate to hijack, I must.  :-\

You have an aftermarket OD unit right? I assume it is mouted behind the t-case? If so, do you compensate for speedo error when calculating your mileage?

I still find your mileage claims hard to believe, I'm not saying you are lying, but 20 mpg is still hard to swallow. My much more aerodynamic, lighter, OD equipped, synthetic oil everywhere, 31" tires, 3.92 gears, fuel injected 2000 1/2 ton at best got about 14.5 when new, all highway miles. Now, it gets about 12.5 highway/city driving.

   My mileage is calculated  the same way....the miles are counted at the rear of the tail housing which is correct and has nothing to do with the splitter, you have an auto also which takes away from mpg unless it's locked as for the tc which helps.

Yes,  but it doesn't matter if it's the tail housing of the splitter or the t-case or the trans it's still only calculating the tires and gears to the speed of the driveshaft, the splitter has no effect on anything past it.

I don't know anything about your splitter, so I must ask, where is it mounted, after the t-case?

Just for arguments sake...
If it is after the t-case, and if your speedo was still hooked to the t-case (which I now know it is not), then the speedo would NOT be accurate.

Geeze you're vaque. How about yes or no. Is the splitter after the t-case?

Based on your response, it sounds like it most likely is after the t-case, in which (as I said before) if the speedo was hooked to the t-case, it would NOT be accurate.

Alrighty then, I stand by my above statement, a speedo connected to the t-case would not be accurate.

Yes, but it doesn't matter if it's the tail housing of the splitter or the t-case or the trans it's still only calculating the tires and gears to the speed of the driveshaft, the splitter has no effect on anything past it.

Tell me how a change in ratio occurring after where the speedo is connected would not affect speedo accuracy?
Me thinks this is why they put a speedo connection in your splitter, it would not be accurate otherwise.

  What change....where is your speedo calculated from.....driveshaft speed...just like mine..just like everyones,  except for some newer vehicles that calculate it from the computer and trans gear x rpm...again the speedo is reading shaft speed and nothing else...the splitter and everything before it is the only thing changing...the speedo is not before or in the splitter,  it is only reading shaft speed from the what the tires are making the rear spin it at

  What change....where is your speedo calculated from.....driveshaft speed..

Normally yes, but more specifically the tailshaft speed of which ever gear box it is mounted in.

In your case, you have the splitter following the t-case, so, tailshaft speed of the t-case would be different from driveshaft speed and it is also variable.
If your splitter is acting as an overdrive, this means the tailshaft speed of your t-case is slower than your driveshaft. If your splitter can also act as a gear reduction (I don't know if your splitter is capable of this or not), your t-case tail shaft would be spinning faster than your driveshaft.

This is why they bother mounting the speedo cable in a t-case on a 4wd as opposed to in the tranny like a 2wd. You can't have a variable reduction after the speedo cable connection point and expect it to be accurate.

The speedo cable is mounted to the tail shaft in transmissions and t-cases and measure only
the driveshaft speed whether it is in a t-case or a trans the tail housing is just housing the rear shaft and seal beyond all gearing increases or reducing effects they might have.
    The tailshaft is never different then driveshaft speed

Monkey bars.  3:00.  I'll bring the radar gun.

Topic at hand:

I'm glad you went v-10; It's just a cool engine.  Sorry about the gas prices.  I agree with the previous posts; taller tires, taller gears.  I'm sure you have the extra power to spare out of the engine bay.  Enjoy your truck.

The tailshaft is never different then driveshaft speed

If you have an OD unit, and it is engaged, the driveshaft is spinning faster than the output shaft (called the intermediate shaft in A500/A518's) of the trans itself.

What Kendall has been getting at, is with an aftermarket OD unit that mounts after the trans tailshaft, if the speedo is still reading based on the trans tailshaft speed, it is not accurate, because the driveline is spinning faster than the trans output shaft with the OD engaged.

The speedo cable is mounted to the tail shaft in transmissions and t-cases and measure only
the driveshaft speed whether it is in a t-case or a trans the tail housing is just housing the rear shaft and seal beyond all gearing increases or reducing effects they might have.
    The tailshaft is never different then driveshaft speed

SM gets it, you're still not getting it. If you haven't caught on by now, there is nothing else I can say but the same thing, again.

None of this really matters,  I'm just being persistant on this hoping, just hoping, he'll admit just once, that he may have been wrong. This would earn Marty some respect points from the KThaxton camp, after all, isn't that what we're all after?  ;D

      OK for the mentally challenged this time...

   
    MY SPEEDO READS THE DRIVESHAFT SPEED...THE DRIVESHAFT SPEED LIKE IN EVERY VEHICLE IS NOT ALTERED BY ANY TRANS,  T-CASE  OR SPLITTER...

    THE TAIL HOUSING    NO MATTER WTF IT IS ON......THE TAIL HOUSING    IS ALWAYS ALWAYS LOCATED ON THE FURTHEST MOST POINT OF THE DRIVELINE BEFORE THE DRIVESHAFT....IF YOU HAVE ANYTHING BETWEEN THE TRANS AND THE TAILSHAFT HOUSING IT IS NO LONGER A TAILSHAFT HOUSING,   BUT AN ADAPTER TO ANOTHER UNIT...

     WTF is wrong with you...can you be that ..

    THE OUTPUT SHAFT IS ALWAYS ALWAYS SPINNING AS FAST AS THE DRIVESHAFT.


     Do you have some invented in your mind thing that is inside your slip yoke slowing down the output shaft yet able to let the driveshaft spin faster and yet not have any problems,  and keep up the speed of the vehicle...if you do please share this brilliant piece of mulit million dollar hardware.

     I can't believe i had to explain TAILSHAFT housing and OUTPUT shaft

Ok, for the MORE mentally challenged....We know how your speedo is in the splitter, but remember, you said...

Yes, but it doesn't matter if it's the tail housing of the splitter or the t-case or the trans it's still only calculating the tires and gears to the speed of the driveshaft, the splitter has no effect on anything past it.

Remember, we are speaking hypothetically that IF the speedo was coming out of the t-case and you had a splitter following it, it would not be accurate.

Now you're just getting really picky and mincing words in order to side step the issue.

The output shaft of the t-case isn't spinning the same speed as the output shaft of the splitter.

Since we are getting nitpicky, bent out of shape, and mincing words, this statement is technically WRONG.  The trans on a truck with a divorced Tcase has the TCASE mounted AFTER the TAILSHAFT of the TRANSMISSION.  There is no adapter.  Just a intermediate driveshaft.  There's your multi-million dollar piece of equipment.  ::)

      Are you retarted...how many times did i say tailshaft housing...the tailshaft housing on everything is located right in front of the driveshaft,  at the shafts tail....that means the very END.    IF you call things tailshaft housings that are adapter flanges or even adapter housings because you don't know what it's called then you need to do some homework...i wouldn't call an adapter flange a tailshaft housing...and i know where a tailshaft housing is located,  if you would put a speedo gear in a adapter housing you really would be retarded....are you done trrying to be stupid

     SM you are retarted since there is no intermediate shaft...

   When you 2 get done figuring out wtf a tailshaft housing is and where tf a speedo is located that is calculating driveshaft speed....like i said umpteen times,   we can get back to drag on a vehicle and what soaks up energy and causes drag...but i wouldn't get involved if i was you 2 since you are easily confused between tail and adapter

Sorry if I don't have the correct name for it.  How about "the short driveline between the trans TAILSHAFT (or are you still calling that an adapter flange or adapter housing?  Funny how if the same trans is on a 2WD it is a TAILSHAFT) and the divorced transfercase"?

Must be swimming in rice by now.

the driveline is spinning faster than the trans output shaft with the OD engaged.

     WTF  are you crazy..the output shaft is the only thing connected to the driveshaft and it is spinning the same speed as the driveshaft...output shaft is connected by a slip yoke or a end yoke to the driveshaft...where in the hell are you coming up with this.

    Where in  the world did i mention divorced...

You're mincing words again.  A 727 output shaft does not magically lose its name when you bolt an aftermarket OD unit to the trans.  It is still the transmission output shaft.  The GV unit has an output shaft that connects to the driveline.  OK.  But the original output shaft of the transmission connects to the GV unit (through an adapter) does it not?

Thus, henceforth, and therefore, the transmission output shaft is not connected to the driveline, and spins slower than the driveshaft with the OD unit engaged.

Geeeeeeeeeeeeeez

  No you are changing words,  the trans becomes the main shaft,  you can't just keep adding output shafts....so then you would say what the output shaft broke...ok so change the output shaft....no you mean the main shaft or  trans,  when you start getting into other shafts as in auxiliaries they all have there own name you just don't continue to call it all output shafts
because it's not anymore.   
       Doesn't matter this was stupid,  i don't why a particular person contiually tries this stupid shit and then keep on with the bs like i would have made a stupid mistake as to where and what the speedo is calculating not to mention the trip i do the tests on is 218 miles anyway....

Ok, lets simplify things so you can understand.
In order, we have:

An engine, then a
tranny, then a
t-case, then a
Multi speed splitter.

We'll call them 1,2,3,4 respectivly. Engine has an output, the tranny, t-case, and splitter all have inputs AND outputs. The thingy on the end of each that turns, we'll call the output shaft (wether this is the textbook term or not  ::)).

You are saying that we could have a speedo cable connected to #3 and have a variable speed #4, yet still have an accurate speedo reading.

If you still don't get it, I'll draw and scan a picture, this way we can't argue definitions.


Edit, removed duplication of words. I typed "all have" twice, I can admit a mistake. ;D

       No you have an Engine  and it's Flange, then you have a Transmisson or the Mainshaft ,  then you have a Transfercase  or  Intermediate shaft with a Splitter  or Auxiliary  then you have a Tailshaft Housing....only 1 tailshaft housing there...isn't that just utterly amazing...terminology is everything....you can't call the adapter between the trans a tailshaft housing or the adapter between the t-case a tailshaft housing...

    Where in this world did I SAY you could have a speedo in a adapter between the tcase and splitter  or between the intermediate and auxiliary...I saaaaiiiid  TAILSHAFT HOUSING.

  Now in between  all these   Transmisson  Mainshaft  Transfercase    Intermediate  Splitter   Auxiliary  you have adapters..............not Tailshaft Housings

Pick up a 727 or 518 rebuild manual (a factory one)

A 727 has an input and an output shaft.

A 518 has an input shaft, an intermediate shaft, and an output shaft.

You're right, terminology IS everything.
