Diesel truck guys.....

[Kells81]

Well after a couple of Hemi's I ponied up one of my 1500's and purchased a 2500 Ram last night. Ended up with a 6.7L HO 4x4. Anyway I was getting stellar mileage out of my Hemi powered truck and would like to max out on the mileage I can get out of this bad boy. I know what it is and I know its not a civic and dont expect that kind of mileage. I would like to get in the 20 range though. I was getting 22-26 over the tank out of the truck I traded for this one. I know this is a gun forum but usally the type of people who own these trucks usually own a weapon or two.

Anyway Performance chips, do these work and will they increase mileage?

Tire size, this thing came with some chrome clad steel wheels as I didnt like the others and planed on getting aftermarket anyway. What is the largest tire size I can install without getting a lift. Its already higher than my jeep that had a 4" lift so would prefer not to go higher with it.

Picked this up to pull a fifth wheel with once every now and then. Will be heading back into the box soon so it will do the same thing my last few vehicles were good at, sitting there lookin good.....

Any suggestions from the veteren Diesel truck owners. What to look for, what not to do etc? I.E. DONT PUT GAS IN IT...

Re: Diesel truck guys.....

1. Most important add on is located in your right foot and is internally connected to your brain. Drive like you have an egg between your foot and the gas pedal.
2. Anticipate green and red lights so you keep rolling until the light turns green.
3. A good set of gas mileage tires will help. Low rolling resistance.
4. Keep those tires properly inflated at "COLD" pressure.
5. There are programmers that will help with mileage but I don't personally know what kind of real world increase it will give you as apposed to modified driving style induced mileage after software change.
6. Maintain your equipment and it will save you more money than the increase in mileage. I have simplified that!
7. If you are pulling make sure the trailer has properly inflated tires, and good ones.
8. When towing attempt to keep it light. Do you REALLY need to take every single ATV and toy you own if you are just going with your wife?
9. Make sure it runs at proper operating temp. Cold motors mean accelerated wear and poor mileage.
10. I will have to think these are just off the top of my head.

Re: Diesel truck guys.....

Amsoil diesel fuel conditioner, at a minimum. Makes the injectors last a lot longer. If you want it to really perc, chage to Amsoil engine oil, transmission fluid, and rear end oil. Should improve the milage 5-10%, better acceleration, and infinite engine life. Synthetics rule. Wait til about your first oil change to switch them out. If you cant find an Amsoil dealer local, contact me.

Re: Diesel truck guys.....

I haven't owned a diesel but have friends who have owned them and played around with tuners/etc. You can get a tuner that will give you more torque and hp and also give you better mileage if you don't have a lead foot. A friend had a Banks 6-gun that was pretty sweet. Just a simple dial on the dash with 6 positions. #1 is basically stock settings, #6 is all out balls to the wall. If you keep it on setting 2-4, you can get good mileage and have power on tap if you need it. IIRC, he averaged 16ish in town and 22-24 on the highway. This was with a lifted truck with 35" tires. Pretty good all things considered.

 

[Bradu]

Re: Diesel truck guys.....

You won't pick up much mileage from a tuner unless you do a dpf delete along with it. If you plan on pulling a 5th wheel, you don't want lift kit. Btw, if you do your own maintanence, prepare to be pissed off the first time you change the fuel filter.

My first experience changing my 2002 f-250's oil ended up with 15 quarts of black as night oil on the garage floor thanks to a hole in the bucket I was using. Bad memory.

Re: Diesel truck guys.....

Tires make a huge diference on my truck, 2004 Duramax, 6spd manual trans. I run load range E 265/75R16 at 65psi, I had to lift the front end about 2" so they wouldn't rub on the bumper when turning. I get about 15mpg when I have the mud & snow tires on the truck, when I put the highway tread tires on I get 21mpg. I could get better mileage but I run the truck hard. My truck is not chipped, but I had a friend who is a service tech at the dealership where I bought it flash the ECM and it runs a lot better in the mid range and top end. The only other mod to my truck is a K&N air filter and I ground down a lip on the inside of the air cleaner housing where the mass air flow sensor attaches to allow better air flow.

Re: Diesel truck guys.....

Put a leveling kit in the front and you can run 33's easily.
A chip with a "fuel mileage" feature will help you out some.
Keep your foot out of it and your gas mileage will be great.
An air intake can help the engine breathe better and help gas mileage...

Drop some diesel fuel additive in the tank every once in awhile to help keep it running clean.

 

[The Mechanic]

Re: Diesel truck guys.....

You should see how many updates there are on a typical 4 to 5 year old Duramax ECM. There can be more than a 100 different updates to fix this or that, and then more to fix the problems some of the fixes were supposed to fix. They used to come out almost one a week. They have them pretty worked out now though. I can not imagine that Dodge and Ford would be any different in programming to fix different problems.

Programming is one of the first things I check for when doing any drive ability diagnosis.

Re: Diesel truck guys.....

Hate to break it to you but that 6.7 is going to kill you. Your main problem will be the emission crap. Between the egr and dpff you have one clogged up cummins. Now you can delete all of that and you will have to get a chip to trick the motor or you can deal with it. If I were you go check out dieseltruckresource.com tons of info there and lots of smart guys. But congrats on the new truck im sure shes a beast best of luck.

Re: Diesel truck guys.....

I have a Dodge 2500 w/ 6.7 Cummins.
It is a great truck but I would advise you not to go to the dealer and let them do an update for cleaner air.
I fell for that and lost power and a lot of mileage, like 4-7 MPG.
They have problems with the DPF and their answer to that is to shoot more unburned fuel into the DPF and hope you get it hot enough[exhaust tamp.] to clear it.
I don't think warranty covers DPF so it is on you.
My truck has about 49,000 miles total and an extended warranty purchased by the previous owner, so I hesitate to delete the DPF but do know how the truck ran before they[Dodge/Chysler] did this re-programming and when to go 'Blow the Cobs out of it."
I do think that you can get something called a Power chip, that that re-programs the engine and will put it back close to how you bought it, but I am not sure.
I am now at a point that I think the thing to do it get a delete kit and chip and not worry about smoke in the air.
I live in a rural area so I would probably be the only one who saw the smoke, however, I don't want to lose the warranty either.
What do you do, shoot unburned fuel on a DPF and make the tree huggers happy or make the truck run and lose the warranty?
I am beginning to think that I will trust Cummins for building a good engine and let the smoke roll.
I am not sure. Regards, FM

I dont know about the trucks, but I have an 05 MB E320 CDI (diesel). The ones since 2007 are called Blu Tec, and dont run as well and dont get the mileage of mine (10% less). A friend has one identicle to mine except for the year model and the Blu Tec stuff, and verifies that. They do run cleaner though.....you dont see that belch of unburned fuel or what ever it is, coming out the tailpipe.

Re: Diesel truck guys.....

Here's mine. 06 4x4 2500 Cummins Those are 33"s on 20" wheels. I have added a leveling kit from Hellbent Steel http://www.hellbentsteel.com/product/dodge/dodge-leveling-kits.html If your interested check them out. Waaaay cheaper than pro comp and the other big names. I tried 35"s and they would have tore the front fenders off if I would have turned with them on. Haven't tried a chip or programmer on this one, because I honestly don't drive it much. Got it new in 06 and have around 50k miles on it now.

 

[Foul Mike]

Re: Diesel truck guys.....

Do any of you know how well the Dodge 6 speed auto transmissions are holding up?
That is one of the things that holds me back as to deleting the warranty on this by making or adding modifications to the engine.
So far, all is well, and I have used a Power chip that has helped some.
I had to take the truck in for an exhaust leak , on warranty, but used the Power chip to set it back to Stock and they didn't say anything about it, just fixed the problem.
I wonder how it would go if the trans. went shithouse and I showed up at a dealer with that.
The engine is great and has all of the power a person would want and then some even on the lower settings of a Power chip.
If the trans. cratered out I would want to go to an Allison. Is that possible?
All advise would be greatly appreciated.

Re: Diesel truck guys.....

Since I use this truck as the prime mover for my 5th wheel trailer, and it is high enough already, I am not looking to raise the truck or put on bigger tires.

Re: Diesel truck guys.....

All kinds of performance mods for the oil burners. You can add a lot of HP with enough cash. I have a 99 7.3 with a lot of mods. The funny thing is the more HP you get out of your plant the next weak link in the system is exposed.
First: Do you live in a Pollution controlled state? IE CO. If so make sure you know what mods are legal to pass inspection.

Keys, the motor has got to breathe! A good intake will help, there are a lot of them out there. Next is Exhaust. IF you do not have the Cat converter a 4-5 in straight thru will help a lot. If you have a cat or DPF check to see what will not void your warranty. The whole in out thing will be felt at the pedal and the pump.
IF you go with a chip I would install a set of gauges! These are vital if you are increasing your HP. EGT is a must if you are towing, if you get to hot you can back out of it with your foot and save the motor. Tranny is helpful if you have an auto, boost is just fun to watch.
Tire pressure, and I found a double shock kit for the front of my truck took the whoops out of it and improved the handling. I run a fuel stabilizer year round, and am anal about my filter and fluid changes.

Re: Diesel truck guys.....

You'll be hard pressed to get the milages you are talking about out of that truck. I've got the 5.9 cummins in my '06 dodge 2500 and the only time I get into the low twenties is on long trips where I set the cruise control at 65mph. I probably average 15mpg on an average tank, which is mostly driving around town. The fuel itself isn't near as good as it was 5 years ago when I got my truck, not sure if the additives fix that or not. I have 60k on my truck and just put on a fresh set of tires. I went with the Nitto Terra Grapplers because I wanted something all terrain, E-rated and in the 305-70-17 size. They are a perfect fit and don't rub anywhere throughout the whole turning radius. I'm pretty sure I lost an mpg or two from the bigger tires, but need to have my speedometer recalibrated to know for sure. Congrats on the truck.

Re: Diesel truck guys.....

I skimmed through most of the post and I don't think this has been mentioned but if it has I apologize, but if you do decide to go with a tuner and DPF delete you will have to be careful depending on where you're from and emissions testing, Its not a problem here in Ky but I know it is a PITA in a lot of states..

I have an 08 Duramax and love it.. got a programmer on it and deleted DPF and straight piped it, give me about 3-4 MPG, well worth it...

 

[Foul Mike]

Re: Diesel truck guys.....

CO does have emissions laws but they are not state wide, as far as having to get the vehicle checked. That is mostly Front Range and probably in ski areas infested with trust funder/slat rats.
I live in the boondocks and at present don't fall under all of those rules.
Who knows, it might be just around the corner.
My 07 has 43,000 miles on it and came with an extended warranty for 7 years and 70,000 miles.
With my luck, if I did a delete of the DPF and a chip I would get about 10 miles down the road and the trans. would go shithouse and the dealer would say that because I did the delete, "So sorry, you altered the vehicle so it is all on you."
I have a feeling that if something like that were to happen today, before I did a delete, I would hear the same kind of shit from the dealer and the only reason the exhaust leak was fixed by them was because Cummins picked it up.
I don't know how good Dodge is with these extended warranties when it is on their dime. I would guess they would try and weasel out of anything they could.

Re: Diesel truck guys.....

I cannot imagine what on earth the DPF delete could hurt. if anything I can see the truck as more reliable w/the delete.

Re: Diesel truck guys.....

I am still wondering about the reliability of the Dodge 6speed auto transmission.
I have heard stories anywhere from they are good, to expect them to fail at 60,000 miles if pulling a trailer.
I don't know what to think.
I am kind of in a 9 line bind because I have this extended warranty, but wanting to put on a delete kit that I think will make performance and mileage better.
What do you do?
All advise appreciated.

Re: Diesel truck guys.....

Your mpg will be false if you run oversized tires , you should get better than what it shows ..do a manual test to verify
most programmers deliver best MPG when set on Kill...but you have to stay out of the throttle or it will go south in a hurry..
do as many deletes as you can legally get away with ..open up the exhaust and air intake as much as possible

Re: Diesel truck guys.....

Thanks for the reply's, averaged 18mpg this week working in north Dallas over 500 miles. Not to bad I guess. Looking for the right set of tires/wheels for it. Right now am looking into Nitto Terra Graps, and some sort of 6-8 spoked chrome or chrome and black rim. 4 wheel parts has but 3 get one free on pro comp rims which come out to a bargain compared to what I paid for the ones on my jeep. Not a gear head by any means but if I dont set it up right now I wont bother with it later.

Not bad for 32k, plus $1500 for Nerfs, rear seat DVD, Remote start added. Didnt get cab lights or the tow mirrors but at least its not white or black

 

[Landis45]

Re: Diesel truck guys.....

Hey!!! Nothing wrong with black!!!!! lol
The Nitto Terra Grapplers are great tires, That is what I am running and got about 10 k on them right now and they seem to be holding up great so far. I do recommend getting them in "E" load rating, especially since you'll be towing. My tires are over size but the programmer I am running allows me to adjust my speedometer accordingly so that My gas mileage will still be right.

Congratulations on the truck, the wheels and tires will really set it off, throw some tint on glass and you will be GTG!!!

Re: Diesel truck guys.....

I run a stock size (265/70R17 E) set of Michelin AT/2 tires on my 2006 Ram 2500. They are simply the best tires I've ever run on a mainly street driven truck. Handling and ride is great, traction both wet and dry is excellent. I would avoid going wider on the tires than necessary if you want to keep your fuel economy. The tall but skinny 285/75R17 Nitto Dura Grappler are a good road tire in that size. You should be able to score a set of takeoff factory aluminum wheels on Craigslist for cheap, they are strong and look good. I haven't found any aftermarket wheels that don't stick out too far for my taste, most run 5" backspacing, factory is 6.5".

Mid 20 mpg's is unrealistic on any of the late model Cummins trucks. My 06 doesn't have as much OD with the 4 speed, but the best I've ever gotten in my stock truck was 21.5 mpg hand calced on a flat 65 mph road trip. The best tuner on the market for the Cummins is the Smarty from Mads Electronics, the Jr model should be plenty for the average guy.

Here's mine:

Re: Diesel truck guys.....

Got my first diesel a month ago - 2008 Chevy 2500. Drove it a weekend and got around 12 mpg. Local guy didn't do much on Chevys and a friend on another board suggested Trey Fox in Augusta, GA. He spent a day on it early the next week. Chipped it, increased transmission line pressure, put in an Air Dog and an exhaust. Mileage is now around 18 to 19 on highway driving hard. Very impressed with his work; I've tried to break it since he did the work, but it's held up well and has more power than I can use. Trey's number is 706-318-0852 if you want to run some things by him. He seems to know his stuff.

Re: Diesel truck guys.....

If you chip it, be very careful how you run it, or be prepared to purchase a new transmission in the future.

I have a 3500 SRW megacab, 2007 w/5.9L, and I'm getting between 18.5 and 20 MPG per tank in city/hwy driving.

I have an Icebox intake with Amsoil filter, and Cool Hose to my turbo, as well as having the icebox modded on the bottom with a 3" flexible hose to bring cool air up from the bottom of the truck instead of hot air from the engine compartment.

Amsoil Aux. oil filter, and running Donaldson ELF OEM oil filters.

additional CAT 2 micron absolute fuel filter between my stock filter (Baldwin 7 micron ablsolute) and the CP3 with braided steel fuel lines.

Banks intercooler and intake.

Mag-hytec transmission pan and rear diff cover.

autometer 3 guage cluster with EGT, fuel pressure, and boost reading.

I have an aux transmission filter kit, but still need to install it.

6. Maintain your equipment and it will save you more money than the increase in mileage. I have simplified that!
7. If you are pulling make sure the trailer has properly inflated tires, and good ones.
8. When towing attempt to keep it light. Do you REALLY need to take every single ATV and toy you own if you are just going with your wife?
9. Make sure it runs at proper operating temp. Cold motors mean accelerated wear and poor mileage.
10. I will have to think these are just off the top of my head. </div></div>

And

1. You will not get 20 mpg out of a 4 wheel drive diesel, just be prepared
2. As far as over sized tires; put a leveling kit on and you can run pretty large ones. In the winter I run Maxxis Big Horn 305/70/17 on the factory wheels. May through November I run Nitto Terra Grapplers (all terrains) 295/70/17 and they drive waay better and get better fuel mileage.
3. Unplug the EGR valve now! No engine, especially a diesel wants dirty, hot air going into the intake. You will get a check engine light, put a piece of black tape over it if it bothers you.
4. I've changed the oil every 7,000 but I'm going to shorten that to 5,000 or 6,000. Change fuel and air filter every other oil change. Yes the fuel filter will piss you off! But it can be done if you're a little mechanically inclined.
5. I'm a carrer fireman and a steel fabricator, my days off from the station. There is not a week that goes by that I don't have a trailer hooked to my truck. Use the exhaust brake all the time. Put the transmission in Tow/ Hual mode when you have more than 800 pounds in or behind the truck. I've had no transmission problems what-so-ever. And I've put 20,000 behind that truck pulling up and down hills.
6.Don't baby the truck and don't hot rod it. The service manager told me the day I purchased mine "drive it like you stole it" I don't do that but I drive it somewhere between that and a 90 year old that can't see well.
7. I just put an Edge tuner on and a DPF exhuast delete. The truck is not sick anymore. It runs like it should. The DPF is choking the hell out of it, and it's an extra 100 pounds or so that you're toting around. I gained 4 mpg (18-19 mpg now) by getting rid of the f-ing factory exhaust.
8. While you still have the DPF installed use the high idle feature. If you don't you'll clog up the filter.

I am so close I can taste it. Averaging 18 over 700 miles city/hwy I am pretty sure I can tweak and get 20.

Re: Diesel truck guys.....

my deleted 6.7 running a 120 horse tune will see 19-20 highway and 15-17 city, prior to that i was seeing a whopping 12 city and a max of 16 highway. that being said, i have to drive it like a granny to get 20 highway, driving go fast style i still see 16-17 average.
as to the question of how to get fuel mileage, you will have to get rid of the DPF at minimum due to the fact that it uses a 4th injection event on the exhaust stroke to (regen the filter)which just dumps tons of fuel down the pipe and raises your egt's to close to 1800*f. once you turn off the 4th injection event and take off the dpf it will cool down considerably and will quit dumping extra fuel and also raise your fuel mileage in turn. With reguards to the EGR, that is an optional delete, i still have mine, but it is deactivated. I have had no problems with it just sitting there cluttering up my engine bay, so i'm going to leave it till the rest of my warranty is up then it will come out just in case i have to bring it back to the stealership for some kind of warranty work.

The best I have ever gotten out of mine (08 4 door SRW Duramax) was 22.6, And yes that is hand calculated, that is over about a 100 mile trip, setting the cruise on 63mph,

I'm waiting for the new 4cyl cummins Nissan titan which is reported to get 30mpg.

Re: Diesel truck guys.....

This is the same as committing internet suicide... Or ask how to make your diesel smoke more!!! I think that might even be worse lol
