I wanted to get some opinions on what shock oil you all are using. I'm running Bilsteins 2.5" triple bypass on my Jeepspeed, and was told by Bilstein to run 5 to 7 weight shock or hydraulic oil with a minimum temp of 300 degrees. Looked online and saw mostly Fork oil when I searched for it. I have seen a lot of people say that synthetic ATF will work just as well. What do you think? Please include specific brand info. Thanks.
