Also Nitrotane is not a good choice, after a few gallons it will cause the internals of your engine to rust, at first it seems all good, but after a few gallons the internals will have rust, and it can easily cause your rear bearing to go bad, this has happened to me and a few other people I know, and I have heard about it from other people on the web.
