Seeing a program on valve deposits from not using a Tier 1 type gas. I was thinking, what is the proper way to remove these carbon deposits without disassembly? Does Auto-Rx work or LC (LubeControl)? Or, some additive that can mix with gas or oil?
How to remove carbon deposits from valves?

Chevron Techron
Redline SL-1
Should help a bunch
or a good fuel injection service such as BG. From what we have seen in the some works great.

I have great success with Chevron Techron.
Most of the quality FI/IVD cleaners out there will clean off the dirty valves.
Add Regane, BG44k, Amsoil, 3M, VentilSauber, and some of the marine 2-stroke fuel additives, to the above list.
I recommend 3-4 bottles a year and recommend rotating among the various brands.
Berryman, 3M, and Lubegard also have do it yourself kits to clean everything up.

I would try Gumout Regane in the clear bottle.
BIG freakin hammer and a chisel! UUUUh you said without dissambly

hot tank?
schaeffers 131 fuel additive will eliminate the carbon off your valves. I would think chev techron would also but I really don't know.
here is the tech sheet for this additive. http://www.schaefferoil.com/neutra_fuel_stabilizer.html

Engine vac at a reputable garage.
I want to see the program. What is it? (It wasn't Pat Goss, was it?) Are you sure you have these deposits?
Personally, I use both FP60 AND Top Tier, but as preventive measures.
How about water injection through an engine vacuum line? I've done it on my Expedition, but I guess there's no way to really know if it removed any valve deposits........
Yes it's Pat Goss from Motorweek. A Shell oil rep was there explaining what can happen to valves (carbon buildup)without the use of Tier 1 type gas. The rep did not push a perticular line of gas just wore the Shell logo on the shirt. I think there will be some depending on the type of engine and driving style, so I post to ask questions on which products to use that would remove these types of deposits.
Thanks to Laminar Lou for his link to a list of Top Tier Gas.

I have rebuilt a lot of engines and every one that I tore down had heavy carbon deposits on the valve's. This stuff is really hard to remove so after reading a few post in this thread I have to ask.
Some say brand xxxx or yyy works for me. What do you base that statement on. Did you remove the head and inspect the valves.
I don't want to offend anyone but it would be nice to see something more than the advertising hype of a product as to how effective it is.
Has anyone got prove that this miracle in a can actually works.

I am in the same corner on this topic. To me carbon deposits on valves are darned near rock hard with the consistency of pumice. I have yet to see them effectively cleaned with any gas additive. I have dealt with carbon deposits so bad on intake valves it caused hard starts and excessive crank times as the deposits soaked up the fuel from the injectors. The only effective method was using abrasive media to blast the deposits off of the valve backs. If there was indeed a chemical that could clean real carbon from valves I would stand in line for it.
At best the fuel additive chemicals would offer a SLOW cleanup or a preventitive measure IMHO. I wouldn't expect "miracles" from a single can, maybe a case used over an extended period of time would clean things up. My humble suggestion would involve prevention from the start using "top tier" gasolines as much as possible in conjunction with periodic applications of Techron or some equivilant fuel system cleaner. I sincerely believe that this type of treatment will save fuel,decrease emissions ,extend engine life, and result in lower overall operating costs. This is the operating plan in effect for all of my vehicles.

In fleet service we have looked inside of engines to determine if such products work. They do, but are very slow. You have to be consistant. A product like Schaeffers 131, or Chevron ProGuard has to be used every third or forth fillup for quite a while (don't use if any more often than that). One shock treatment does not do much. Also preventing it with a maintenance does of something like FuelPower will also help. The real problem is that these products take time to work and people do not want to wait for anything.
