I was thumbing through one of my diesel magazines and came across an article that said you should run diesel injector cleaner through your tank once in awhile. Is anybody doing this? What do you use?? Do you notice anything?

I have been using Diesel Kleen with cetane boost and have noticed a small difference. I got my truck used and was not sure what the previous owner did in the way of maintenance but when I started using the diesel kleen about every other fill up I have noticed a bit better pickup and response to the throttle. May just be the cetane boost???? There are several different types of Injector cleaner out there though. This is just one of many that I think works.

One word , Seafoam !

I didn't know you could use seafoam in diesel. Though, I never checked either, thanks!

Diesel Kleen works for me;)

what is this seafoam stuff you speak of and where do I get it... I'm about to change my fuel and air filter so this would be a good time to implement something of that sort also

I use seafoam in 2 stroke motors and while they claim it can be used in Diesels I recall someone saying they used it and had some issues as a result. I would be interested in hearing some positive results because the stuff worked great on 2 stroke motors.
You can get it at NAPA for those who never heard of it.

It appears from reading Seafoams Material Safety Data Information (http://www.seafoamsales.com/pdf/MSDS_SFTT_US.pdf) (MSDI (http://www.seafoamsales.com/pdf/MSDS_SFTT_US.pdf)) that it contains 10-20 percent alcohol. While it may be really good stuff, GM has a specific warning on alcohol based fuel treatments except in case of emergency of Gelled Diesel. There are many discussions about fuel treatments in the fluids section of the site. GM recommends if any fuel treatment is needed to use Standyne fuel conditioner. Of course GM has a Diesel Fuel conditioner available (part # 88861009) recommended in TSB 03-06-04-017C. I don't know what you'd pay for it though. Letting your dealer know that you've used any other conditioner could result in problems down the road.

It is my understanding that alcohol is an emulsifier actually combining with water and passing it through the fuel filter which may harm the injectors. (and alcohol will harm rubber hoses) Again there are many discussions on the board about this.

So.... I would not use Seafoam, PS Diesel 911 (http://www.powerservice.com/diesel_911.asp) (red bottle) or FPPF Meltdown (http://www.fppf.com/meltdown.asp) unless it was a gelled fuel emergency.

As always the search function of the site will produce spectacular results such as this: http://dieselplace.com/forum/showthread.php?t=116363&page=3

anything that emulsifies(alcohol) will stop the filter from coalescing water as it passes thru, filter will need to be changed after using up fuel with it in there.

There are many types of additives which can be used but dont use anything which contains water or alchohol.

Lucas fuel treatment. I used to sell it in a speed shop i work in. it's awesome try it

I use the white bottle of Power Service in the winter and the grey in the summer.

Loads of info about additives in the Fluid Discussion section.
http://www.dieselplace.com/forum/forumdisplay.php?f=14

Most of the fuel additives that we use for lubricity are injector cleaners also.....I use Stanadyne myself which I add to every tank

Diesel Kleen is my primary but I have found some from Cummins that I got one heck of a deal on that I mix with the Diesel Kleen 50/50 and I now use it every other fillup.

I use 4power made by Conklin. it has worked well for me. I use it every 4000mi and their Diesel Plus every fillup if you want to try some PM me.

I only have a little over 4k miles on my Duramax so I doubt I would notice any difference yet, but I have used Marvel Mystery Oil in several tanks just for the lubricating properties. On my wifes trialblazer (gasser) that I have maintained since it was new and now has 124 000 miles on it, it was hesitating something feirce for a while with no change after changing the sparks. So I dump in a half a pint of MMO and after round trip to & from work next day she says it is not hesitating at all. It's been smooth & nice ever since & I still put it in both vehicles every other tank or so.

I dont know if antying works, or what works so I mix it up :) Whatever is on sale every couple tanks, howes or power service, maybe some marvel maybe some gunk stuff.

I am gonna hijack your thread or rather put a different twist on it, whats your take on injector cleaner?????????? Run it from the factory and keep the injectors clean or does the stuff work well enough to let it build up a ltitle bit and then use it. Ie does the truck need it when new or not

There is a machine like the one for gassers intended for diesels. www.bgprod.com has it , but it is a bit salty for me at the moment. Some local shops have it, but I have not heard any reviews of it yet.

:exactly:

I use Diesel Kleen in the summer and Howes in the winter.

I also used Lucas's didn't see any real gain with it. If it is an older diesel that hasn't had any ran through it it does clean it up nicely. My old Ford dropped about 2 MPG ran Lucas through it (300 gallons of fuel with Lucas) and it brought my mileage back up. I quit using it and it remained there. From then on about once a month.

I started running it all the time now more for the lubricity and ULSD

If I start running something like power service on a consisten bases, am I going to have to change fuel filters more often??

and never had anything ran through it, perhaps initially. If it has "gunk" in the lines and tank it may clean it out and go to filter

After you get the system clean, or a new truck, and run it regular, no. I chage mine by the DIC every 15,000 miles.

On changing the fuel filter I recently purchased a WIX #33910 for my LBZ. I've never replaced one yet and see that there are 2 "O" rings. Should one lub the "O" rings before installing them with the spin-on filter. Is so with what (fuel or oil)? What is the proceedure? I'm new to fuel filters on diesels.

The big o-ring is for the top of the fuel filter and the small one is for the bottom for the wif sensor. Members have put them on dry, have used vasoline, can use a lube for o-rings available at diff. auto parts stores. When you use a lube, use a small amount. The last one I did, I put it on dry. Did not have any leaks. Do what you feel comfortable with.

a dab of diesel from the old filter.

There is a good write up on how to change your fuel filter in the DIY section

I lube the O-rings with dielectric grease to hold them in place.

I use Enviromax Plus every tank. Makes your fuel burn quit clean and keeps injectors clean and carbon build up down to hardly anything. Makes your fuel burn complete (which means in diesels more power and and more efficiency and efficiency=better MPG). I actually have engine in my shop that I used this in and by looking up in exhaust amazes me, 185k miles and its clean, no carbon buildup. This has no alcohol or water. I can give weblink if anybody wants to learn more, just ask. On their website it has MSDS report (shows everything in stuff).

I'm not crazy I just love this stuff. I did oil analysis on since using ULSD and the metal wear is very low so its also lubricates like old diesel used to.

I usually run lucus fuel injector cleaner through every 3k and I add a half a quart of reg motor oil every fill up to help keep the mech fuel pump and injectors lubed up. The lucus really helps my gasser I can really notice the difference when I add it.

Valvoline max Life fuel system cleaner ($6 to $7) works.
It claimed to basicly bring fuel tank senders back to life.
My tank sender was on its way out. It would go on a wild tare all most 50% of the time, it would read peged way past full (and open or loss of signal) or totaly empty (shorted I guess).
I figured that I would put this stuff in and it would do nothing and I would post on here saying it is a waste of money.
Now my fuel gauge reads correctly about 99% of the time.
I took the Max Life with some gray Power Service and mixed it with about 14 gallons of ULSD and no motor oil. There is still a little motor oil in my fuel but only a few % now.

Interesting read...if you look at the patent info for Enviromax Plus, you will see the fol quote (seen in several places throughout the patent):

"As noted above, the bicyclic aromatic and inorganic metal oxide components of the invention are dispersed in a solution comprising at least 90% by weight of a carrier liquid selected from the group consisting of a hydrocarbon fraction in the kerosene boiling range having a flash point of at least 100 degrees F., a C.sub.1 -C.sub.3 monohydric, dihydric or polyhydric aliphatic alcohol, and mixtures thereof. Preferably, the carrier liquid is comprised at least 80% by weight of an aliphatic alcohol selected from the group consisting of methanol, ethanol or isopropyl alcohol, and no more than 20% by weight of kerosene. More preferably, the carrier liquid is comprised of at least 80 wt. % methanol and from about 5 wt. % to about 20 wt. % kerosene."

Sounds to me like a good percentage of the stuff is actually alcohol based. Hmmm...

Did some more reading on the scientific basis of using the metal catalysts (found in Enviromax Plus) to improve combustion and HC emissions. It seems that it actually does work fairly well, but even in the scientific study, the carrier solution that they used for the catalysts was comprised of a good percentage of alcohols mixed with the kerosene. I am not disputing the fact that the product works well (as it seems to), but the fact that they are using alcohol as a good portion of the carrier solution, and we all know what alcohol can do to our injection system...

Have buddy that been running 2 years on Enviromax and nothing bad as happened, he just put new (well rebuilt) injectors in (just for precaution b/c of mileage) and when he pulled out he said his actually looked better than rebuilts, lol. I myself have been using for a year now and no problems at all. I was very skeptical when I tried it, and I mean very skeptical, lol. I am glad I tried it, it's awesome stuff. Anyhow thats my $0.02.

I agree that the metal catalysts help burning of the fuel more cleanly, that has been proven scientifically. What I have a problem with is the alcohol that is used as a carrier for the catalyst. It is a known fact that the alcohol with emulsify any water in your fuel system, allowing it to get through the water separator and filter, and when the water reaches the injectors, it causes damage. If you have no water in your fuel system, it is not a problem, although the alcohol could also absorb water out of the air. If there is water in your fuel system, this could conceivably do some damage. This is my only concern.

Hey guy go on their website and look at burn test they did with water in fuel. They compared to Lucal and some other additives. Just watch the 2 minute thing on your computer, you will amazed.

I like using and will continuing to use it, you guys use your own stuff so its all good. Im not a salesman for this stuff, yes I do tell people about it, yes I do sell it but I am not a saleman really for it. At my shop I always have some on counter, if people ask about it thats good, if not I won't bother them, same as on here. I just stating my personal findings.

I have always used Sea Foam or Lucas on my gassers..... so I went to Sea Foam website and see the same product is also Diesel rated..... I was very impressed with the way it took care of my 6.0 gas engine injectors .... so I will be using it on the LBZ as well..... used Lucas a few times when the Sea Foam was unavailable but do not know if its Diesel approved....
