There is a reason it says "max" and not simply "full". I prefer to stay a little under the max. No reason to push the envelope. As it is, I'm in the upper part of the range and that makes me feel comfortable.
Mine doesn't have a "Max" on the dipstick, it has a "Full" so I put it at that.
I think this is just chosen wording and not anything else.
