Anyone use the diesel fuel injector treatment for their trucks. How often? The mechanic at the dodge dealer suggested running it through every tank. I think every tank would be a waste of money.

I have also been told the same thing. I run Lucas fuel conditioner about every third tank full but probably should do it more often. Your 3rd gen is a little different than mine but I have been told that it helps keep the VP44 IP lubricated better in the 2nd gens.
www.stanadyne.com This is what I started using. at about 6K on my new Duramax I started smoking down the hwy (bad fuel?) the dealership said no codes were being displayed so nothing they could do. I did two things Add Stanadyne Lubricity (with in buring 1 gallon no more smoke) Stoped buying fuel at the sh***y truckstop(kinda old and run down) I was going to for EVERY fuel up. I bought a case (24 8oz bottles, 30gal treatment) of Stanadyne's One Shot Performance Formula fer 50 bucks off the internet. I put a shot in for every tank full. My main reason why: Diesel is DIRTY, I have read several articals that cover why diesel is so dirty and how Lubricity and Centain levels are low to start with. Adding the OneShot brings up Lubricity and Centain and my Dmax loves it. From what I have read Diesel fuel was never intended to be use in the high pressure FI systems our diesel rigs have nowa days so without the additive the injectors tend to gum up real quick. The smoking issue I had was a symptom of an injector sticking open... Hope this helps Burt
You do know that GM has a pretty firm stand against additives of any type don't you? Don't get me wrong, I use Stanadyne too, though I'm out at the moment. And seems like I saw the GM was softening their stance a while back. Then there is the emuls/demuls argument. Demuls is dangerous with the extremely high pressures on the GM common rail (and others now too) and the very tight/sensitive tolerances of the Boche injectors. If it makes it through the filter, or falls out on the post filter side, you can have serious failures. And some say emuls is also bad due to the profusion of tiny droplets acting as an abrasive on the injectors due to the insanely high pressure. But they also frown on added filtration and water separators as well as lift pumps when doing warranty work. Can't win…
Duno what an emul or demul is? From what I remember reading Stanadyne is approved by GM... Talk too me???
I run the stanadyne performance formula through every tank on my 6.2. Better fuel economy, less smoke, and according to the butt-dyno, its a tad quicker as well. I plan on putting actual track times to that as soon as the track opens to find out if it really does help performance at all.
Emulsifier/Demulsifier. Cause water to suspend in the fuel or drop out respectively. Stanadyne was approved for 6.2/6.5, but officially, they approve and warranty NO additive for the DMax back when I was watching/researching stuff.
Burt, BadDog, and Joez.... You know...you guys ARE in the Dodge Tech forum. Not only that but the original poster asked about additives in his Cummins Dodge, not his duramax. opcorn: Just to let the three of you know, we also have GM tech forums.
Ya but it is still a fuel additive disscusion sort of. I am using the Stanadyne performance formula in every tank. Could't tell ya if it helps or not. I doubt it hurts. The one thing that I did try for one tank and I think it quieted the truck down was biodiesel. I ran 1 tank of B20 and by half way through the tank I think the truck ran quieter and smoother. I just didn't like the fact that it was .30 per gallon more. Not worth it to me. This was in my 05 Dmax. I am a fan of additives myself so I say a good quality one.
Well my co-worker uses Stanadyne in his CTD so oke: :stir: opcorn: I found the Technical artical on this from GM: Bulletin No.: 03-06-04-017 Date: March, 2003 INFORMATION Subject: Information on Diesel Fuel Additives The use of diesel fuel additives is not required or recommended for the 6.5L diesel or the 6.6L Duramax(R) Diesel engine under normal conditions. The filtering system is designed to block water and contaminants without the use of additives. However, some customers may desire to use fuel additives to improve the characteristics of available diesel fuels. Water Emulsifiers and Demulsifiers If the customer desires to use a fuel additive, care must be taken in its selection. There are two common methods that fuel additives use to cope with water in the fuel. One method is through demulsification of water in the fuel. This method causes water particles to combine together to form larger particles, which drop out of suspension. This allows the fuel filter/water separator to separate the water from the fuel as it is designed to. The other method of coping with water in the fuel is through emulsification. This method, often using alcohol as the emulsifier, keeps water particles suspended in the fuel. Emulsification of water in the fuel can allow water to get past the fuel filter/water separator, in most cases causing damage to the fuel system. Only alcohol free water demulsifiers should be used in General Motors diesel engines. Both *Racor(R) and *Stanadyne(R) diesel fuel additives are alcohol free and utilize water demulsifiers to cope with water in the fuel. Other brands may be available in different areas; be sure that they clearly state that they are alcohol free demulsifiers before use. *We believe these sources and their products to be reliable. General Motors does not endorse, indicate any preference for or assume any responsibility for the products from these firms or for any such items which may be available from other sources. COMMON DIESEL FUEL CONCERNS Fuel Waxing/Icing Fuel distributors blend # 1 and # 2 diesel fuels for seasonal requirements in a particular region. No other blending of fuels is recommended. However, a customer may desire to use a winter fuel additive to prevent fuel waxing or icing during extreme cold snaps. If a winter fuel additive is to be used, it should not contain alcohol or other water emulsifiers that may compromise the water removal effectiveness of the fuel filtering system. Bacteria and Fungi Growth Bacteria and fungi growth can occur in diesel fuel when there is water present, especially during warmer weather. The best prevention against bacteria and fungi growth is to use clean fuel that is free of water. There are diesel fuel biocides available which are designed to kill bacterial growth in the fuel system. However, the dead bacteria can still cause blockages throughout the fuel system. If bacterial growth is found in the fuel system, the proper method of removal is to flush the fuel system using Service Manual procedures, replace the fuel filter element, and refill the tank with clean diesel fuel. If a customer desires to use a biocide after flushing the fuel system, it should not contain alcohol or other water emulsifiers. Low Cetane Number The cetane number is one indicator of a diesel fuel's ability to ignite. There are many indicators of overall fuel quality such as cleanliness, specific gravity, volatility, viscosity, detergency, corrosion inhibiting abilities, and lubricity. Increasing the celane number alone is not a fix for poor quality fuel. Additionally, increasing the cetane number beyond the engine's requirements will not increase performance. However, the cetane number of diesel fuel is not always consistent and some customers may desire to use a cetane improver to ensure full performance of their engine. If such an additive is to be used, it must not contain alcohol or other water emulsifiers. Poor Lubricity The 6.5L diesel and the 6.6L Duramax(R) Diesel engines are designed to operate on today's low sulfur fuel without the use of additives. A fuel additive designed to increase lubricity is not a fix for poor quality or contaminated fuel, but some customers may desire to use a lubricity additive to aid in the longevity of their fuel system components. If such an additive is to be used, it must not contain alcohol or other water emulsifiers. FUEL SOURCE ISSUES If a vehicle is properly maintained but has fuel contamination issues, consider obtaining fuel from a different source. Purchasing fuel from a high volume fuel retailer increases the chance that the fuel is fresh and of good quality. Bottom line GM says if you choose to use an additive it must not contain alcohol or other water emulsifers. Sounds to me they left it up to the customer and it does not void any warrenties unless you use the wrong type of additivewaytogo
Oh crap, I didn't know. Thanks. I was just reading all recent threads and stumbled in here. I won't let the door hit me on the way out. See ya around!
Yes, i do. I click on "new posts" everytime i visit, and read everything that comes up. I saw a post about fuel additive, I responded with my experiences.
oke: opcorn: Yeah, about running it in all of your Dmax's. rotfl Not in my house.....You're in the Dodge Tech forum... imp: rotfl :stir:
Me personally, I'm going to have a hard time paying for additives. I don't put additives in my engine oil, and I find it hard to believe that it's necessary in the fuel.
Not necessary, but makes up for lack of quality fuel that is sold at a lot of gas stations that also sell diesel. Fuel from truckstops is noticably better, but if getting fuel there is not an option then additives can make up for the lack of quality and "freshness" of the fuel.
