[Vwdiesel] ATF as an additive???

Interesting story about "Power Services" diesel conditioner (okay, maybe
just a little bit interesting): The Bosch service place near me sells
their brand of fuel conditioner / pump lubricant - called E-Zoil Diesel
Aid. The guy there sold me on it the first time I brought a pump in
with a main shaft leak.
I used that for a number of years, then one day saw Power Services stuff
at Fleet Farm for cheaper than the above stuff. Said it lubed the pump,
so I tried it for a while. I work in the medical field, so I use a
syringe to add the right amount every fill up. Never had a problem with
the first stuff, but with Power Services additive, the rubber on the end
of the syringe would swell and become useless after a few times.
Eventually the stop solenoid on my Vanagon started to stick so it would
either not start, or keep running with the key off until I knocked it
with a hammer. I replaced the first one, but the new one did the same
thing after a few months - lightbulb came on and I switched back to the
first stuff and the stop solenoid problem went away.
I am saving the Power Systems stuff just in case I ever get a pump leak
that I want to swell the rubber on though...

Hello Gerry.....I admit to being one of the ATF users, but I don't
recommend it, and I don't use it regularly....only about once a year,
specific reason: Several times in the past 3 years my turbodiesel
pump displayed a leak that dribbled fuel out of the little rubber nipple
that empties the turbo boost enrichment module of the pump (upper right
of pump, standing ibn front of bumper facing the engine.)
A quart of ATF in the fuel tank caused the gaskets/O-rings/whatever in
pump to swell up enough that the leak totally stopped. The fix lasted
a year, and then I had to do it again. So, it is a one-tank trip with
whatever unfavorable additives that arrive with the ATF.
My injector pump still works after several such fixes, and I haven't had
have it rebuilt yet, which is the only other way I know of to stop a
leak. I figured that the worst case would be that the ATF wouldn't work
and I would being paying 300-400 for a rebuild anyhow, so why not try
I'm sure the fix will only last about a year on my car, and I will have
do it again, and I'm not sure how many times the pump will respond in a
positive fashion to the swelling agent, or how long it will take for the
friction additives to cause some damage, so the test continues.
I will report the results annually.
I do admit to using the 2-stroke oil now and then, but more as an
experimental thing, just to see if I can detect any benefits. I have
using "PowerServices DieselKleen + cetane boost" in almost every tank
winter. Seems to make the engine start and run a little smoother, or
me to imagine such a result. Who knows? I should probably get a TDI and
my poor old Jetta out to pasture. Gad, what an incredible car that has
been. It deserves an honorable retirement.
