Poll: Who has used the ATF treatment?
I have read about the ATF treatment to reduce carbon buildup and improve compression, and am considering a high mileage T2 and am wondering if doing the ATF treatment might be worth trying? Has anyone tried it on a T2? I would like all imput from na owners as well. Thanks!

Out of these 652(not counting yours) threads, you should have enough input to make your decision.

I have done it on a severely flooded 2nd gen. No matter what I did it would not crank so as a last resort I did the ATF trick. I personally think thats the only time it should be done. When you're out of options go with the ATF.

Used it ('91 NA). It worked. Seriously smooth and stronger running engine. Won't ever bother again. If car is running, just get an in car FI service. This will clean your injectors and the solvent will loosen all accumulated carbon in the engine. But, this cost $80-100 vs. $1 (+ rental car) for 48 hour ATF treatment.
Or, go to gas station, dump 2 quarts of MMO and fill 'er up. Drive like mad until tank is empty. Refill gas tank and instant same result(friends '87 NA).
If car is not running(or you have a fly/mosquito problem), then you have no choice but to give the ATF(MMO/any engine solvent/seafoam/chemtool....) treatment a try.
Prevent the need for the ATF treatment with frequent oil/filter changes and a bottle of FI cleaner(rotate brands available) every several tanks of gas.

This thread concerns the ATF treatment, I think I am just offering other equal options that I have seen work.
I am not talking about cleaning the injectors, per se.
I am using them as a delivery media for the cleaning of the apex seals/engine internals. The solvent that is added as fuel(in place of fuel) will go everywhere that the fuel would go. I would think that nobody would have a carbon issue if the fuel/air didn't go everywhere. So, any in car FI cleaning(the kind that disables fuel pump and T's into the fuel line after the fuel filter somewhere) will bleach the injectors and the engine internally. Some will also tap into a vacuum line and clean your intake also.
The Motorvac/CarbonClean/decarbon.... will go anywhere air or fuel goes depending on entry point(s). Plus, they usually also toss in a bottle of concentrated cleaner into the tank. The full effect if very noticeable after running through an entire tank of gas. Most people will not notice the gradual change. Have someone else take your car in for the service, drive it for one tank of gas, and then give it back to you. You will feel the difference.

the idea of atf is to let it sit and dissolve those carbon deposits. if its doesnt have time to soak into the carbon(ie putting something in ur tank and driving) then ur not getting the full benefits of doing it.
i let mine sit overnight, and the next day wow..... like night and day. a good thing if maybe your engine isnt as aggressive as it used to be.
let carbon build up to much and ull get an apex seal stuck.... then ur fubared
uneven buildup across ur rotar housings can cause loss of compression.
