Car Forum / Dodge / Dodge Trucks / January 20072006 2500 MegaCab 5.9L Cummins loses power
A week or 2 ago my 2006 Dodge Ram 2500 MegaCab with the Cummins 5.9L and 6 speed manual started to cough and lose power/RPMs and lots of white smoke (or smoke looking substance like water vapor) came out. (It had an unknown percentage of bio-diesel in it -- small repeated fillups of various percents of bio with intermittentent straight dino diesel -- truck is 4 months old but only had 600-700 miles on it. This coughing and loss of power lasted a few minutes and then it seemed to work fine for a while. Then it happened again. I added 10 gallons of dino diesel and was able to drive home 4 miles without incident. Next day went out and had similar episodes. When it drives fine there is no smoke. When it starts to cough and lag and power loss occurs lots of white smoke comes out. A ton of it. I drained the water filter a few times thinking that maybe there was a high water content in the fuel. I also added some Power Service additive that is supposed to displace water. I was able to drive 50-70 miles without incident when it started again tonight. It would idle fine but when I pushed the accelerator it was like there was a regulator on it. It would rev up a little and then just totally lose power. I added another 7 or so gallons of dino tonight and some more Power Service additive. We are now up close to 800 miles on the odometer. I went and got some Howes Lubricator Diesel Treat, which claims to eliminate water, and added some of that. After that I was able to drive 5 or 6 miles when it started to happen again but the symptoms are now a lot less severe. I don't see as much smoke or any when it "power losses" and it does not lose as much power, though it is still very noticable. It is like a governor is on the engine. It will idle and I can slowly increase the throttle and then between 1800 and 2500 (not always at the same point) the power loss happens and the rpms will drop. I was able to keep it going at up to 2000 rpm without loss sometimes but then get above that and it happens. Any ideas? I started to think that maybe the fuel filter was getting clogged and it was allowing enough fuel through for lower power use but as the throttle is increased it cannot get enough fuel to the engine. But everything is new and there should not be all sorts of deposits to come loose and clog the filter...

Change the fuel filter! While your at it buy a couple of them, sounds like you will be needing them. I'd stop putting anything else in the tank other than diesel. Actually I'd be inclined to drain the tank. I also would not go to the dealer unless you are darn sure you are covered due to the bio you added.

Have you actually reserched this subject or are you talking out of your a.s? Here's the real deal ... 100% FOSSIL FUEL isn't the right answer and NEVER was. 1) It's not renewable (that means we'll eventually run out). 2) It pollutes the air we breathe. 3) It causes war. 4) Adds CO2 and other greenhouse gases to the atmosphere which is causing a shift in our climate. (Did you read the news today? An artic shelf the size of 11000 football fields broke free. Gee ... I wonder what caused that?) There are renewable sources of energy that are BETTER in *every* way. If you want to continue making Arabs rich and polluting our air, then go ahead. It's your right, as an American, to do nothing while others fix the problem.

Environmental Science. Field of study: Alternative Energy. I just completed a research paper on bio-diesel that included: 1) making it. 2) doing the chemical analysis on it. 3) burning it. 4) doing the analysis on the air quality before, during and after burning it. Other than that, I burn B20 with no problems at all and have for last 30,000 miles. In fact, I'd bet my bottom dollar that my truck, burning B20, is going to outlast your truck, burning dino diesel, by at least 50,000 miles. I live about 2000 miles from Iowa.

It is all in models that have been shown to be unreliable. Unfortunately the topic has become politicized so not many scientists will speak out on the lack of evidence and flimsy models. junkscience.com is one interesting place to start (but not the only one). A few interesting things that they don't tell you on the news is that 1) climate started warming [biggest shifts] before the largest increases in CO2, and not the other way around 2) CO2 input affects on climate is logarithmic and not linear. That means that as you get more CO2 in the atmosphere, the effects of that extra CO2 are much less. 3) climatologists, especially paleo climatoligists, who study LONG TERM climate change, do not think that the current bit is more than a natural cycle. I am not denying that the climate is changing -- that is what climates do. Just that man's affect on it is not the cause of the change. I still think BIO is a good thing to do. Better for your engine if done in a quality way etc and also reduces dependency on those wonderful adherents to the "religion of peace" and helps the environment on the polution side of things and makes us less dependent on other countries etc etc etc Chad > I still think BIO is a good thing to do.

Islam-lunacy aside, it's pretty hard to make a case that global warming is not happening. And YES, Al Gore is an idiot. > Islam-lunacy aside, it's pretty hard to make a case that global warming > is not happening. And YES, Al Gore is an idiot. But it is easy to argue and make the case that any global warming that is actually happening is not man made. The scientists who make this claim make it based on computer models, not physical evidence, and the computer models have been shown to be unreliable (fed old data they do not predict where we are today). In the last 7 or so years there has not been an increase in global temperature, btw. (Exact number of years escapes me). The rises were previous. > There is no empirical proof that global warming is man made. Agreed. There is, however, some startling results. The cause of global warming is very difficult to prove 'empirically'. In fact, a true scientist doesn't "empirically prove" anything. They test a hypothesis and document the result that support or do not support the orginal hypothesis. It's up to the public and the government to listen or ignore the results. In short, what we do know is this: 1) We are expelling HUGE amounts of Carbon Oxide (CO, CO2), Nitrogen Oxides and other gases/particulate matter into the atmosphere. Mostly from the burning of fossil fuels, either by automobiles or industrial uses (electricity generation, etc). 2) We know that these gases/particulate matter "trap" heat. > It is all > in models that have been shown to be unreliable. Unfortunately the > topic has become politicized so not many scientists will speak out on > the lack of evidence and flimsy models. I agree to a certain extent. The political red tape that exists for *any* environmental problem is rediculous. There are plenty of viable models ... just nobody to listen to the results. > junkscience.com is one interesting place to start (but not the only > one).

True ... but this does not mean that the amount already in the atmosphere isn't enough to shift the climate. > 3) climatologists, especially paleo climatoligists, who study LONG TERM > climate change, do not think that the current bit is more than a > natural cycle. There are a few that believe this. There are more that believe that we are impacting the climate with greenhouse gases. We know who the Bush administration choses to listen to. > I am not denying that the climate is changing -- that is what climates > do. Just that man's affect on it is not the cause of the change. I disagree. Global warming is not my focus, but I do dabble quite a bit in air quality in my studies. There is enough viable evidence of global warming to warrant that our government take a more proactive role. > I still think BIO is a good thing to do.

Becoming self sufficient is going to be this countries biggest challenge. Especially in regards to energy production and consumption.

We know who the Bush > administration choses to listen to. VERY few. Basically, the guy from University of Denver, followed by a bunch of idiots. Yes the global climate thermal cycling is generally accepted fact. However, the RATE OF FLUCTUATION that is occuring now is essentially unprecedented. Most of these temperature and atmospheric CO2 values going backward in time are taken from direct sampling of ancient ice in Antartica. Pretty simple stuff. Not much room for any debate, amoung anyone who approaches the data unbiased. And dont tell me those guys drilling for ice down there are political junkies... >>>A week or 2 ago my 2006 Dodge Ram 2500 MegaCab with the Cummins 5.9L >>> and 6 speed manual started to cough and lose power/RPMs and lots of [quoted text clipped - 45 lines] > i may be mistaken but i thought that bio blends up to 20% were considered > acceptable by Dodge and Cummins engine company on 06 and later models. You are probably very well correct. My thought is he has "unknown percantages of bio" different amounts of two.different additives and diesel. A fuel sample may be the last thing he needs dc to do, knowing how friendly they are to warranrty claims. I figure it is easier to dump the tank, fill with diesel and see what happens. If it continues then go to dc without all the other crap in the tank. Sorta avoid what could be a bunch of bs imho.

B20 is considered acceptable by Cummins for 2007+ models, last I read. I run B20 in my 2004 and get outstanding results. Like: 1) Less noise. 2) Richer Americans. 3) Poorer Arabs. 4) Cleaner Air. 5) Good feeling from knowing that I'm using a renewable energy source (at least 20% of it).

A ton of it. Where did you purchase the bio? What is the source of the bio? (i.e. Soybean, used vegetable fry oil, etc.) > Any ideas?

You're thinking correctly, if the truck was older, the bio maybe freeing deposits left by dino diesel and clogging the filter. However, being fairly new, that is unlikely the cause. My *guess*, without knowing more, is that you are consistently getting poor fuel or as Roy stated, your fuel filter needs replacing. I would start with replacing the fuel filter and burning 2-3 tanks from a good, known source. Usually diesel from truck stops is fairly safe since you know that the diesel has not been sitting for months. If you prefer bio, like I do (for many, many reasons), I wouldn't burn any B100. Stick with B20 for at least a few more months until some of the big boys start embracing B100. I fill up with B20 from Loves Truck Stop. It is made from soybean oil and is the safest out there. I've never had a problem. Don't give in to the scare tactics of some people in this ng about bio-diesel. Stick with reputable B20 and your truck will run the same, if not better. BTW, not to put a feather in my own hat, but I am pursuing a phd. Alternative Energy is my field of study. So, I'm not talking out my a.s ... I've actually done some research on bio-diesel.

I think that might be happening to you. The different feedstocks that biodiesel is made from affects the jell temperature of the fuel. I know of at least one commercial biodiesel producer that uses poultry fat to make their biodiesel. It has a fairly high cloud point. The cloud point of biodiesel could be as low as 20°F or as high as 40°F. I'd pull a fuel sample from the water drain on the fuel filter, put a thermometer in it, and put it in the freezer. Check it about every 10 minutes and see what temperature the fuel is when it starts to look cloudy. If the cloud point is above the normal low temperatures you see you need to mix your biodiesel with kerosene or #2 diesel fuel to get the cloud point lower. SignatureKen Thanks for the replies. I will report back shortly on my efforts. I am still thinking along the lines of some fuel gone bad. I don't think the fuel was bad out of the tank -- been fueling there for a while and never had issues and they seem to sell a lot. Also, the truck was running fine on the same fuel a while back, but the truck was not being driven a lot so the same tank of fuel had been in the tank for several weeks. We got a bunch of wet and cold weather a few weeks ago, starting soon before this started, and I think the fuel just "attracted" the moisture. The bio in there is from a reputable dealer that most of the bio drivers here (SLC UT area) use. The tank had been 100% full with dino diesel and then over time small 3 to 9 or 10 gallon fillups of various things (some B100 in small amounts, some B50, and some dino diesel) were added as I was trying to keep the tank full to remove available surface area for condensation to happen and just because I like to keep the tank pretty full. The current bio % is probably between 10 and 30 right now. I have all the fueling receipts since purchase and should sit down and caluclate it :-) I am going to change the fuel filter and see what happens and report back. Thanks Chad Ok, with a new fuel filter we seem to be good to go. Went about 65 miles tonight, mostly highway, after the change without issue. Old filter was gummy looking with gelled fuel or something and/or maybe some ice looking stuff. Must of gotten gummed up before I stuck the additives in. I'll run a tank or two through it and change it again to see and to put a real Stratopore filter in (this was some other brand [Luber Finer] I could find on the weekend at a local parts store since the Cummins people were not close and the long weekend coming up). We'll see how this works longer term but I think the problem was the filter getting gummed up. Probably as I had not added much anti-gel stuff and we had a few really cold days and I am not sure what the bio percentage was since it was several small 3-10 gallon adds of various B% and a little straight dino diesel added to a tank of dino diesel... Thanks all Chad |
