I have seen a lot of posts of people saying that it does. mine didn't use much at all though. Also for a lot of your other questions just look through a bunch of the old posts. There is a lot of good info in here!
There are a few bolts you may want to take out and lock tite. I haven't had a problem with these yet, but most people have so they can tell you what should be tightened. However, before you take the bolts out to lock tite, use the old saying don't fix it unless its broken!! I would constantly check if they are loose at all, and if not, DO NOT LOOSEN THEM! Hey, if they aren't gonna come out, why mess with them and possibly cause it to happen?
