Anyone here own a diesel truck? I have been setting my sights on a dodge cummins when I can get the chance. I have never dealt with a diesel rig before and would like to know if there is anything important I should know about?

Will it save me more money in the long run? A guy I was talking to at work said it may not be a good idea as a diesel engine takes more crankcase oil and you have to have an oil additive in the fuel? Not to mention he said that gas mileage is about the same(but loaded down) with gas vehicles(not loaded down). So I would be paying that much more in diesel than gas cause diesel is more spendy.

Input?
 
If it's your regular commuting vehicle and an infrequent hauler/tower, then a gasser is probably your best bet when considering fuel and maintenance costs.

I am on my second dodge.
Buy one you won't go back.
Same mileage as a V6 Ranger??
Twice the truck.
You can use the additive but no required.
Never have myself.
Yup oil change evey 10,000km (6,000 miles)
Fuel filter etc.
They all got their bugs.
Probally look at the GM right now, seems best.
IMHO
 
I have a 05 Dodge 3500 4x4 . I love the diesel. Once you pull with it you will never want to go back to gas. They used to have some issues like hard starting when cold ,taking forever to make some cab heat,louder than you could stand but they fixed all them. I use this truck to do everthing from running around town to pulling big campers,landscape trailers ,boats and anything else that comes up. If i take it easy it will get 18 mpg around town. You cant beat that .
 
I forgot ...No additive here.
Amzoil filter and 12 quarts of oil- $125.00 Can go up to 25,000 miles between changes.Not sure about the new ones.
 
It's the EPA's fault...

You know... diesels used to be really good engines but anymore they suck.I blame it mostly on the epa for making the emission laws so strict. They ruined both the diesel fuel and the engine that burns it. Without the lubricity of sulfur and the way the diesel fuel has to be refined the fuel is not as good as it used to be ( cracked twice now instead of once like before but even before that they just distilled it which was the best way to begin with) sorry for the long quote. This extra refining is the main reason why diesel fuel is higher than gas now other than the exorbantly high road tax.I could go on and on about it but it won't do any good.:deadhorse: The old diesels like the 6.9 7.3 Fords would have been better if they were direct injection instead of indirect. The p pump cummins Dodge trucks are a little cheaper and easier to work on. The 7.3 Powerstroke is a decent engine. But like previously stated the maintenance can be pricey. The 6.0, 6.4, 6.7 are all loaded with emission controls so they cause more headaches than the 7.3 and previous. The Chevy diesels I'm not too familiar with.

Diesel truck - New or Used?

As far as my own exp, I've owned all the big three. My favorites are the Dodge/Cummins. Currently own a 99 3500 dually w/ a full-on Banks kit. Also a 07 3500 srw w/ a stock (325hp) cummins & a 4 spd auto.. a real freight train! Also have a 5500 Chevy 20" stakebed w/ the Duramax / Alison combo.. what a POS. 35000 miles and way too many problems. Just helped out my neighbor today w/ his 07 Chevy w/ Duramax / Allison. He asked me how deep my Terex backhoe could dig / bury it! Guess we just had bad luck with the GM stuff. Ford has hade so many engine revs from international/navistar that I don't trust them anymore. Last Ford dsl '05 1 T. Glad I sold it when I could. No owner loyalty here.. I just buy what works. Still own 3 Fords, 2 Chevys, 3 Dodges, 1 old International ( water truck), plus a lot o lil gas stuff. The new Diesels have way too much emission / computer stuff, so buy the extended warranty!!

What gear ratio are you running to get 18 MPG around town? Youre not going off the factory onboard info are you? My '07 3500 4x4 w/ 4.10 gears gets 18 mpg only when I hit all the lights green!! It gets 19-22 MPG on the freeway if I keep it @ 65 MPH. @75, the MPG tanks. @ 85 the mileage is like a tank.. Way beyond the optimal torque curve- it needs an extra gear!!
 
I do not think I would own another diesel pickup, fuel is higher, repairs are more expensive. I have a 03 ford 350 with a 7.3 and changing the injector cups right now, there always something that is unique to that truck. Have a gas gmc 3500 and other than a radiator no repairs, it starts at 20 below and I can find gas anywhere. Towing is a plus with the 350 but pound for pound the gas job is not that far behind. Now in my wheelers diesel is the only way to go, had a couple of old drill rigs that were on gas trucks and how does the ole saying go about trying to get off the pi** pot.
 
I agree with what everyone else has said so far. In my experience, the older 7.3 powerstroke was a good engine. Had one in a 97 work van that had 493,000 miles on it with only normal maintanence (starters, alternators, pulleys, a couple of sensors, etc) The only reason we got rid of it was because the tranny finally gave out. Funny thing with that was that the mileage didn't start to get good until about 300,000 miles. It was consistantaly 15mpg for the first quarter million, then began to creep up. When it died, it was getting about 19.5.

Other than that van, I've always been a Cummins fan. You'll have the least amount of problems with that, and a chassis that can handle it. The newer Duramax is impressive, but I've seen issues with the injectors, and fuel system.

One thing to add, make sure whatever you get has a cold weather package. A guy at work just bought a Texas truck for the good body. Got it to Michigan and has to keep a good supply of ether handy to start the thing. No glow plugs or water jacket heater.
 
All choices, such as gas or diesel, involve trade-offs. You'll find those that praise diesel, and those that curse them. And it's true that diesel fuel doesn't represent the economic savings as it once did and the new(er) engines have become a technical nightmare when compared to the old(er). Still, depending on what you use your truck for, diesel can offer advantages.

A diesel engine will typical (in terms of miles) last way beyond a gas engine and provide a totally different power curve well suited to pulling heavy loads. Maintenance and repairs are usually more expensive with diesel, but if you look at it in terms of miles driven before replacement is required it ain't far off from a gas engine if you drive a ton of miles each year and/or pull a lot of heavy loads. But don't forget that that diesel engine is bolted to the same basic piece of iron as the gas engine, a six-year-old truck is still a six-year-old truck with a six-year-old A/C unit, steering gear, lighting system, starting/charging system, etc. A diesel may still be running strong at 300k, or even 500k, but now you're looking at cumulative wear and stress put on the rest of the truck, such as the suspension system.

Really, you need to weigh the trade-offs against each other.
Do you need a diesel? Do you drive a ton of miles, say something over 50k a year?
Do you pull heavy loads? How often? How heavy? How far? (keep in mind that pulling ain't the same as loaded)
If you don't need a diesel, and you buy one, chances are good you'll be one of those that curse 'em.

Just my $0.o2
 
Got a 92 3/4 dodge 4wd with about 140,000 on it at the farm. A stout truck that is dead bang reliable.

No not going by the computer. Its always been wrong compared to the calculator. I think i have 3:42 gears but cant remember. Wonder if it will be on the glove box ? I have cold air intake,Bullydog smart pup tuner set to performance. Was told that would be my best mileage if i ran it easy .I try to keep it under 2,000 rpm. .those 4:10 gears are killing your mileage. I also run amzoil although not sure that does much for the numbers. I'm thinking about installing locking hubs.
 
If you want to get into it, biodiesel can take the fuel costs right out of the decision. A farmer up the road from me started making it for all his equipment. I found him by doing a craigslist search on their discussion boards. We got a barter system going and my 7.3 powerstroke loves the stuff!

As stated previously, all choices come with trade offs. This one has been eliminated for me. No cold start issues or gelling. Truck pulls better than my Chevy 2500.
 
I have an 03 with 308,xxx miles on it. Took it into the shop at 250,000 because the accelerator sensor gave up .. 650 bucks.. and got the lift pump replaced at the same time because it was junk. 250 bucks. THEN yesterday i pulled it into a diesel shop because it was -2 and didn't want to start until i shot ether to it. Guys there said i have a bad injector to start with so thats gonna be about $400 bucks. I change my oil every 10,000 miles and drive about 50,000 miles a year pulling a trailer or loaded otherwise for probably half of it.

I get 22 miles to the gallon just screwing around. 26 going down the interstate/highway and almost NEVER average under 20 unless i let it sit and idle so its warm when i get back in it.

My gas chevy i had before this got 14 MPG. so i'm getting 30% more mileage. If gas is $3 and diesel $4 its going to be the same cost per mile in fuel.

Never used a fuel additive. EVER. never added oil to my engine, EVER. never used and oil additives either. Just change oil, put brakes on it, and eventually maybe some ball joints.

Oh, and i backed over some sunflowers and poked a hole in my radiator, which was about a 2 hour job to change but not the trucks fault. :)

I'd buy a diesel if you drive further than 20 miles to work because they are just SO much more efficiant. A 2500 and a 3500 are the same truck in 5 of the 8 models made so just get one with middle gear ratio. Duallys ARE going to eat your fuel miliage... sorry :) but you probably don't need one anyway.

I don't have one myself, but I have seen the same recommendation over and over and over again as a "best buy" in a farm magazine we get. 1990-yr 2000 dodges with the cummins. After that year apparently they changed some things and they aren't quite as good. Still decent but not the same. Note: not me saying that, just other owners. This is from "farmshow" magazine, they have a feature "best and worst" buys, those particular trucks are like 95% best buys compared to all other pickup sized work trucks, no comparison at all. I mean, really. Not to start a flame war but you just don't see the fiords and chevys being pushed as a best buy comparied to those older dodge diesels. All kinza dudes got them with a half a million hard miles on them, still kicking, zip repairs besides like starters, etc. Over and over again I have read that..just might be true.

If I had a need right now for one, a larger pickup, and the scratch, that is what I would get.

With that said, we have access to a variety of big trucks here, from a f450 on up, so I don't need a big pickup if I have a big load. I got an old half ton datsun diesel for my personal ride and *precisely* because of the diesel engine they put in them, an industrial forklift engine. I get right at 40MPG highway, and it varies in the 30s with a moderate load and on the more backtroads and in lower gears. Can't beat it with two sticks for being reliable and good mileage. I see them occassionaly being offered in ace shape for like three grand or so, fair running shape for 1500. Got mine for four hundred but it "needed work" as in the body is a rat (I never cared much about bodies if the drivetrain was doable) and I had to pull the tranny fix a few things, and do some new front end pieces. Have around 800 in mine now, total.

I been through that OPEC nonsense way back (under fifty cents gal to TEN BUCKS over night, and you could only get two gallons max with mile long lines at the stations) and learned my lesson, your fuel cost and availability can change OVERNIGHT, and it won't matter one bit how "bad" and "redneck" someone is with their own mindset and their huge hopped up gasser truck..them big international energy fatcats and wall street commodities speculators could give crap one how "bad" some redneck gearhead is with their 6 MPG bigfoot stump jumper or bonedoed out old rat camaro. They'll be pedestrians real soon if they don't have a huge fuel stash to tap, or they'll be forking over more than their trailer rent just for fuel. And that's just what the fatcats want, all your money.

So yes, diesel has its place, the engines are built stronger, because they have to handle just much higher compression, they get much better mileage cube for cube over gassers, etc, and got the torque you want in a truck. I know I won't own another gasser nuthin, especially with ethanol fuel now and next year they are bumping it to 15% all over (heck, I mean *this year*, supposed to be happening soon). Gonna be killin a lot of older gas engine stuff.

I wish we could get those great european diesel passenger cars over here,(or the smaller pickups like those great toyotas you just can't kill) but for some reason we can't. They have cars over there just as safe, plenty "clean" enough, they get upwards of 80 MPG!!!

Over here they are bragging on 30 and you'll pay through the nose for that. They sell all the electronic add on do dads now, seems the big three, here anyway, have lost sight of what transportation means. That should come first. Heated DVD players with GPS equipped curb feelers and 500 horsepower framis valved muffler bearings and..what the heck IS all that crap they put on new rides anyway , and why do you need so much horsepower just to go to the store or to work? No wonder new cars and trucks cost what a house used to cost not too long ago.
 
12 valve dodges are simple and reliable. The bodies they're in now are hard to find a good one. The 98-02 dodges have injector pumps that die between 50-100k miles. If you get one in those year models get an aftermarket lift pump and filter setup. The 03-04.5 ar ethe best years of the commonrail dodge. 2 injection events and better mileage than the 04.5 to 07. The oil stays a lot cleaner in them also. They have less injector problems. The injectors in the commonrails do go bad. They're about $300 a piece and can be changed in less than an hour. When they go bad put the new one in number 6 that way you don't have to go back there again for a long time. Fuel filtration and water contamination is what kills them. In those trucks aftermarket fuel system is a big plus and will add life to your injectors.

Fords the 7.3 in the OBS seem to need glowplugs and cam sensors. They're not that expensive but aggrivating to change. 6.0s scare me, never owned one. I've got a 6.4 now and the mileage is 15 most of the time. If gets better on highway driving at 55-60. Interstate it's 15 with 3.73 gears and the auto.

Chevy/duramax had injector problems in the LB7. The warranty on them was extended to 7 year 200k miles. All of them except the very last 04s are out of warranty. It's about $2k for a set plus labor. The LLY is the next generation and I owned one of them. That generation gets the worst mileage before the LMM. The LBZ is the one to own in my opinion. You get the 6 speed allison with the selectable gears and good mileage with the best reliability out of them. Never messed with the LMM. The mileage on those seems to be in line with my 6.4.

I've owned 2 93 dodges, 97 dodge, 01, dodge, 02, dodge, 05 dodge, 3 07s 5.9s. One 00 7.3 ford with over 300k on the engine and it's at 400k now. The guy that bought it off me is still driving it everywhere. The 6.4 is a 09 model with 33k miles in a year on it. I had one 04.5 LLy duramax. The mileage was bad on it and it didn't seem to have any more power than the LB7 I test drove before I bought that one. I've got 500k miles or so in diesel pickups in the last 10 years.

Yep have used them for years. Depends on what you use them for, if towing you can not beat them, and they will cost less to run towing heavy loads. As for oil change, which everybody who has never driven one focuses on.. yes they take more oil (more compression, longer throw on crank, hence bigger pan). But other than oil, they are cheaper to run than any of our gasoline trucks. We run Amsoil synthetic.. if you put an Amsoil bypass filter on then you can go a lot longer between changes (the synthetic does not break down) and the bypass cleans out the soot and crap. Keep the bypass filter changed. Amsoil has it on their site.. as do a lot of others. We have over 400K on one of our trucks.. I know a friend who runs two Dodge with Cummins and has over a million on one and about 600K on the other.

As for cost of fuel, most of the time around here it is a few pennies cheaper than gasoline (right now I think it is maybe 2 cents more).. varies up and down (but not as much variance as gasoline - our gasoline prices jump up and down 5 or 10 cents overnight.. diesel stays pretty stable).
 
You've answered the question "Do I want a diesel?" Yes

Now answer the question "Do I need a diesel?" Depends on my driving -hauling needs.

What type of driving and hauling do you intend to do? With that information you can get some real answers. My opinion is diesels are for people who haul big loads and or drive LOTS of miles. If that's not you stick with gas.
