“X-tra Lube Grease is currently being used to lubricate the slipper guides on the Mt. Washington COG Railway Steam Locomotive. There are 10 locomotives in total. Before using the grease, the slipper guides were replaced at the rate of some 800 per year, at a replacement cost of some $10,000 per year plus labor and downtime. So far the results with the grease have been fantastic, reducing wear and downtime.”
