Looks like there is another version of the additive that is called Molyslip The Engine Protection. Interesting that unlike Molyslip E, the label indicates: "M contains a unique blend of super slippery MoS2, graphite and Molybdenum compounds .... The additive is made by Holt Llyod Ltd. Wilmslow, Cheshire. Marketed under exclusive licence from SlipProduct and Engineering Co. Ltd. Made in England." What may these Molybdenum compounds represent ? Type of a soluble form of moly ?
