I did this for about 100 miles. ATF has a degreaser in it that will clean the internals. I would of ran it more, but I was nervous. So I decided to go with Marvel's Mystery Oil. I've ran it for 3000 and am changing it tomorrow. As far as I know, ATF won't hurt much. Just don't use it if your engine's got 150K on it You might break up some of the sludge that's holding it together

/wwwthreads_images/icons/smile.gif That which you have described is one o' them "Oklahoma Fixes"/wwwthreads_images/icons/blush.gif that have been developed to refresh tired and sludgy engines./wwwthreads_images/icons/tongue.gif The ATF particularly affects the close-fitted parts, especially hydraulic lifters, where sludge can inhibit oil flow and the lifters don't want to pump up./wwwthreads_images/icons/tongue.gif This process isn't without risk, as any dislodged sludge can also collect on the screen and slow oil flow to the suction side of the pump./wwwthreads_images/icons/frown.gif That, plus the risk of inadequate lubrication in some high load areas of the engine, makes this process something that I would have reservations about doing to an engine under load on the hiway./wwwthreads_images/icons/tongue.gif I have resurrected a slew of GM diesel cars from the late 70's/early 80's which had been sitting and had LOTS of stuck lifters on startup. The product I used was Berryman's B-22, an oil additive that was only used at fast idle and then only for 20 minutes, after which every thing was drained and then drained again after about 100 miles. The B-22 seemed pretty thin, and was way thinner than ATF. It did, however, work miracles on cars which had been sitting for up to eight years./wwwthreads_images/icons/crazy.gifA little diesel know-how and a good understanding of how to overcome the THREE MAIN screw-ups that GM made in the design of those cars kept me in dirt cheap transportation for quite a few years. Those diesel cars were EVERYWHERE, none running of course./wwwthreads_images/icons/smile.gif

Berryman's B-22 .. thats what you recommend? Now dave whenever I drain it after 100 do I replace the oil filter with a new one?? Or reuse until the last drain??

I usually run 5 quarts of 15w40 oil and 1 quart of ATF in my Jeep. Since I am doing it constantly, things dont get that chance to build up and cause problems. I've never had any problems with it in over 10,000 miles.

 

You noticed any gains? Gas Mileage? ect... I am trying to compile a list of things I need to do to the Jeep whenever I get it..

/wwwthreads_images/icons/smile.gif (1) Pour in the Berryman's on top of the existing oil and run for the 20 minutes. (2) Drain and replace the oil and filter. (3) at 100 miles, drain oil and dump out the filter. You can re-use the filter that was installed at the end of the test if you can drain it well, but I never went to that much trouble. How about using the puny little stock filter for the first drain/fill, and then when you drain at 100, go to the big guy (PH8A) so you can carry an extra quart of oil./wwwthreads_images/icons/smile.gif

/wwwthreads_images/icons/smile.gif Are we to infer, FM "Muddy" Nut, that you are getting into an '85 Cherokee? /wwwthreads_images/icons/crazy.gif

/wwwthreads_images/icons/smile.gif 85 K is NUTHIN'.....mine has 119K already and I still regard it as NEW. Just be sure to use the jumbo filter and you'll wear out the seats before you wear out the engine. Those regular Cherokees are the "sleeper" of the Jeep family. They have WAYYY more capability than people think, with just a minumum of mods. You see pics of them in rocks that would make a CJ sweat./wwwthreads_images/icons/smile.gif
