DieselGiant speaks the truth.
EDIT: "Where in the Factory Shop Manual (FSM) is the procedure for cleaning the injectors wrong?"
None of it is wrong, it just uses ~30 year old techniques.

Where's the proof???


To this day, those are the only techniques that work.

You could run 50 gallons of DP through clogged injectors and it would not clean them. You can soak a clogged injector nozzle in DP for a week and it won't clean it. It just doesn't work.

My proof is in the cars I've used it on. Not just MB's. Even a lowly Ford Escort diesel showed a noticeable difference.

Not everything can be fixed with diesel purge. If the injector tips are worn or water has damaged the IP, no liquid can fix them.

i was just wondering...i just bought a w201 190 2.6....is there a "diesel purge" equivalent for gas engines? just wondering......

Also: i havent used diesel purge myself...i did use SeaFoam....and it DID clean out the engine...it was used in my 300SD and a friend's K5 Blazer. The Blazer blew out dirty smoke like crazy. It was driven around the block nearly clouded up the neighborhood..I dont doubt whether these products work or not...they do...

BG 44K is some of the best stuff on the market for gassers. You can find it at most auto stores.

There are effective products to clean injectors on gassers but not for MB 616/617 diesels.

The difference is the way the injectors are built. If you ever take apart an injector for a 617 you will see why a purge product will never work. It would be obvious to any kritter with a body temp. Read the book.

This links to a good thread on our diesel injectors:

It mentions a good reason not to use Diesel Purge. People so delightfully report success with this product because of that crud coming out of their return line. They assume that is a good thing, it is not.

That proves that you can fool yourself and so can DG. It proves nothing of the claim you made earlier about DG speaks the truth.

Let him tell us where the FSM is wrong about cleaning injectors. Diesel Purge sure as hell won't unclog injectors.

LOL, Let's agree to disagree.

You think you are right and I think I am right. No amout of bickering will change our minds.

I had my injectors removed after 110K and had them tested. One was leaking and had a bad spray pattern. They had to disassemble that one and clean it up. Afterwards, it specked out at the right pop off pressure and had a good spray pattern. The wife even noticed that the car ran much better. She is an automotive idiot so I use her as a test since she doesn't know what affects what.

Question. Is it that difficult to take out the injectors so you KNOW they are working correctly as opposed to hooking up the stuff and hoping it does something good? I mean, has anyone every had the injectors tested bad, hooked it up to that stuff and retest? That would be an excellent opportunity. After all, coming out clean after the second run is one thing. Whether there is still crud and buildup in the injectors is another thing and probably more important.

You need to check the book and see the inside of the injector for the 616/617 engine before you have an informed opinion on this subject, and certainly before you argue about it.

I'm laughing all right, but it's at you, not with you.

Personal attacks will get you far in a debate...

I stand by my words: "You think you are right and I think I am right. No amout of bickering will change our minds."

Welcome to my ignore list. :vanish:

Great suggestion. A scientist among us (though I'm sure there're more).

Separate question. Does anyone know the procedure for testing spray pattern/ general Injector diagnosis? Possible to do this in your home shop?

THX

People argue this stuff and they have never seen the inside of an injector. If you look at one it is obvious that there is no chemical that can clean them.

Search, this has been discussed many times before.

I have posted the ingredients in these products as listed on the MSDS sheets. If you read them it is obvious that there is nothing in them that is worth your money.

I have posted the ridiculous claims made in the advertising for these products. Anyone who reads them can be sure that most if not all of them are lies.

I started out the target of many detractors when I spoke the truth about these products. We are now down to few superstitious true believers.

Anyone, what part of the fuel injection system do these products clean to benefit the system? They most definitely do not clean the injectors.

What diesel engine manufacturer endorses the use of these products?

What engineering standards organization can find benefits from the use of these products?

And once again, if it makes you feel good, buy it. Don't buy it blindly, it is a feel good product.
