Don't wanna sound like a crazy sales guy, but I prefer Kano Kroil as a penetrating oil. A few drops of the stuff on any rusted bolt and it's friggin amazing. http://www.kanolabs.com/
I wouldn't use it as a lubricant though past getting seized bolts freed up, but really it's 100% replaced WD-40 for me when working on rusted and old equipment.
