I always used tranny fluid.. I still do that on my old trucks when I
do tune up's or oil changes. Water can even work as far as knocking
off carbon. But I always like the auto tranny fluid.. I think it soaks
in a bit better to break up the stubborn carbon.
Both my old Ford trucks use 6 cyl engines with Carter one barrels..
One is a 1968 F-250 with a 300, the other a 1974 F-100 with a 240.
They get the tranny fluid carb blast every once in a while..

that's probably a bad idea on any car with a catalytic converter. A mix
of water and ATF will do much the same thing, and "decarbonize" the
engine as well.

Sure was. Unfortunately, I was racing a 1974 Charger, lost control, and
flipped it on it's roof.

Someone told me if you were driving the car "spirited" that the back end
had a tendancy to come loose and come around on you...

He was 100% correct....

I do work for 7-11, and I asked one of the managers what they sell for
gas. He said it's all brand-name...Sunoco, Texaco, Exxon, etc. It's
basically what's left over after they have met their needs and they sell
the remainder off.

This has NOT been a problem the last couple of weeks!!

This is my 'work' car and gets anything from 12-200 miles every time it
goes out, usually 10-25 mile romps and then shut down for ~ an hour.

Fits the prescription!
