Smells like snake oil. Here are some questions: 1) If it's so great at reducing friction, and is a one time deal, why don't the car makers add it in at the factory? They would get better EPA mileage and wipe up on the competition. The added cost per car is negligible. 2) Why don't some oil makers add it to their oil? Look, the benefits of Boron! OTOH, motor oils already have boron compounds in them for friction reduction. Hmmm, something smells rotten. I would say that this product has all the classic symptoms of snake oil and does no good except to relieve one of some money which can be better spent by the owners of motor silk. Rumple
