I use ATF, in the hope that it would reduce the tendency of my (fully wet) V3 clutch to have the plates stick together overnight. It hasn't, but having used it in gearboxes for years, thought it was probably OK for chains etc. So far, so good. However there are a bewildering variety of ATF fluids around now, has anyone any idea what is best? Or at least, doesn't eat bearings, like EP90 GL5.........
