Exactly! The dipstick has two marks but the manual does not specify what's what (min/max cold? or hot? or max cold and max hot?). Pretty sure I opened a thread about it long ago and no one knew. So filling to the top mark when cold is a bad idea. I just let mine settle itself (by puking its guts out at the track) and haven't bugged me since.I think most people overfill the reservoir. Mine leaked like crazy during my first track event 8 years ago. I corrected it during that weekend and I've tracked it at least yearly without a seap.
