I have read that many have tried this in their front forks with some degree of success. After discussing the matter with a friend, he informed me that road racers use to use ATF, however, the problem was that the oil weight was too inconsistent from one bottle to the next. One container might be 7.5 weight and the next might be 10 weight. Is this still a legitimate concern to take into consideration or can one feel a little more confident in a consistent weight from bottle to bottle with the Mobil 1 ATF. Also, does ATF have the same anti-foaming properties as does high quality fork oil? Just some questions rolling around in my head. Would appreciate any discussion on this topic. Thanks!
