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..

Modern fuels seem to have done away with the practise. 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. nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel

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....

Will depend on what brand they claim to be.. 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! |
