Where are all the advocates & know-it-alls now?

I can’t blame ANYONE for not wanting to keep reading this thread. I don’t even want to anymore. However, as is the case in many things, the best comes near the end. I’m sure that not enough people are going to be aware of at least this one persons’ experience of engine failure related to the use of X-66.

Perhaps 450 SLC 50 can elaborate a little bit on how the X-66 was used, what the prior condition of the engine was like, and what exactly happened?

I personally think it would be of great service for a new thread to be posted, as most *rational* people gave up on this thread long ago.

How about it 450 SLC 50?

You Bet. I gotta go so I dont have time to write right now, but I will post over the weekend. You can count 2 motors here. I know someone else that had a meltdown when using it.

NOTE:
As of September 9 2009 this product is no longer available through any of our sources...

We haven't purchased any X66, nor do we plan on purchasing any.
I swore I wouldn't post here about this any more, however you guys seem to want to keep ranting about it.
A few customers inquired about it, I made it available.
It's was only by drop shipment.
Buy it or don't. I assume if you do, you know how to read the label.
I am not trying to piss anyone off here either but get real, it's only a decarb. I've used decarbs since the 70's and never did I loose an engine with it, in fact I've saved people money, thinking they needed an overhaul, ie carbon knock knock..
We want feedback from all of you but don't imply we're trying to dump a load of this off on our customers.
I must admit one thing, I've never had to put this into a Mercedes.
It all comes down to maintenance, doesn't it?
Have a great day everyone.

It seems that a few people think I work here, I just play here. The only money ever changing hands between my business and theirs has been when I paid for advertising of our radio dept on this site.

I say this because for me to defend them I can't be seen as a part of them. I seriously doubt that Mercedesshops.com would remove your post without it at least having been viewed. Did you see your post? I suspect that you lost it at your end. I say that having lost at least ten long posts over my time here. I have always believed it was my machine or a lack of co-operation over the net that caused this, but I'm not a computer guy. I have watched the activity here enough to know that isn't the way it works. The only posts I have seen removed (my own included) were posts well off the group purpose of real information and definitly more towards personnal aggression. They just don't like a good fight (bg).

I can also vouch for the fact that their business style is based upon the modern inventory concept of "just in time". Meaning they don't stock anything (or not much). They are selling co-ordination; you need the part and they put it there. No profit in them touching it first.

As to X66, I have never seen the product do any damage, human or mechanical (does mess up the air we all breath). I can imagine serious consequences for its misuse in both catagories. I have never seen it bend a rod , but I thought I did it one time (turned out to be misfire identification problem reset with a key cycle, but I had a dead hole for much longer than it should have took to clear).

I think it is good that bad experiences get reviewed as a further warning but I just don't see a conspiracy here.

Steve,
What product do you use by Techron?chevron for decarboninzing a diesel engine? I have only seen products for a gasoline engine. Do you jusr pour it in the tank or is it introduced by another method?

Steve??

Anyone have any updates on the diesel question about Techron??

Here's some information for you, CJ:

As for what Steve is likely to have suggested, I would assume that it's Chevron Techron Concentrate, Fuel System Cleaner.

• Here's a quote from the FAQ's at:
  
  www.chevron.com/prodserv/nafl/L2_A5_a.htm
  
  "Can I use TECHRON® Concentrate or PRO-GARD® in a diesel engine?"
  "Chevron fuel additives are designed for all carbureted or fuel injected, spark ignition engines. Techron Concentrate can be used with diesel fuel in light duty indirect injected diesel engines, such as Mercedes Benz and Peugeot. We do offer Chevron Dieselmotive for direct injected diesel engines typically found in light and heavy duty trucks."
  
  And newer direct-injected Mercedes-Benz diesel engines too...
  
• Here's the link to information on Chevron Dieselmotive:
  
  www.chevron.ca/ProductsServices/Commercial/FuelAdditives.htm
  
• Personally, I would stick with Redline DFC/85+.
  
  www.redlineoil.com
  
• Or Stanadyne, that is the only diesel fuel injection manufacturer in the world that makes it's own additives:
  
  www.dieselpage.com/additive.htm
  
• Or even Lubro-Moly's products like DIESEL-SPÜLUNG, DIESEL-SYSTEM-CLEANER, or PRO-LINE DIESEL INJECTOR CLEANER:
  
  www.liqui-moly.de
  
• And remember that Redline and Lubro-Moly are sold right here at PartsShop...

At risk of restarting a flurry here are some observations from one who is knowledgeable about the chemistry of many automotive cleaners.

Stuff that has ingredients with alcohols and ethers (methoxy, ethoxy, butoxy, etc. ) are excellent solvents for gums and varnish, AND lots of polymers (like seals and gasket, RTV sealants, fuel injector bodies, O-ring seals,etc.) They DO WORK.

However, I strongly recomend folks first try at least one treatment with TECHRON. It safely and easily cleans up most fuel system and combustion chamber deposits.

Of course one should also buy good gasoline, not the cheapest stuff around. Federal regulation mandate a minimum amount of detergent in gasolines to 'keep clean' the injectors,etc. It's ok fo rmoderate cruising , light load, moderate heat soak operations. In hot climates, or cars that run in heavy stop/go, or short trip operation, gasolines that advertise 'clean-up'i.e. 'drive your engine clean!' and similar performance really do that. They have demonstrated in testing that level of performance, and it is REAL.

NEVER pour liquid into the intake system of a modern engine unless: 1) You don't care if it breaks and maybe blows up in your face 2) You are VERY SKILLED in this art, or 3) someone else will pay the bill,

for customer with plugged EGR passages.

Hey RTH, digging up an old post on GM X-66.

Upper Engine and Fuel Injector Cleaner | ACDelco
