The thing a few people seem to be forgetting here is that FireClean is not only a lubricant, it is also a cleaner and a protectant. Mobil 1 and all the other lubes and or secret recipe concoctions that have been mentioned here do zero for cleaning or protecting the firearm any where even close to what FireClean does. As I stated up thread, I've seen dudes in 3rd world countries using olive oil on their weapons as a lubricant without issue, that doesn't mean its as good or a better solution than other products just because it works. If you are going to compare products make sure its apples to apples across the board.
