Liquid Rescue, formerly Liquid Bearings, is the synthetic lubricant that consistently outperforms all others currently available. It has incredible low and high-temperature characteristics, which is absolutely necessary for proper train lubrication but completely lacking in petroleum-based oils. Don't use them on your trains any longer! Actual oils leave sticky deposits when the short-chain molecule components evaporate over time. Real oil is made up of a mixture of long and short chains of carbon and hydrogen atoms, and under certain conditions the short-chain molecules evaporate, and the unstable molecules oxidize and break down. This leaves a sticky residue which can actually "gum up" the device it was intending to lubricate. Conventional oils also contain varying amounts of impurities, such as sulfur, waxes, and unstable hydrocarbons which are left behind as residue deposits. In contrast, synthetic oils are made using a process that re-arranges the structure so all the molecules are uniform in size, shape, and weight, an ideal phenomenon which does not occur in nature. While petroleum-based oils that are extracted from the ground must then be refined to attempt to minimize their shortcomings, synthetics are custom-designed to produce the ultimate lubricant, with inherent performance characteristics vastly superior to any petro-oil. It is perfectly safe to begin using Liquid Rescue on all your trains immediately, even if you have been lubricating them with conventional oils for years or decades. It is fully compatible with all vintage and current oils, and will eventually flush away the residue of the evaporated real oil over time. You will easily notice that all of your pivot points, slides, bearings, rollers, and gears will move easier with Liquid Rescue, especially if you have been using petroleum-based oil on them for years. We always offer our anytime 100% refund if you are not delighted with Liquid Rescue, so please consider trying it!
