The Mobil Mobiltac MM is a high-performance, non-diluent, heavy-bodied gear oil formulated for the lubrication of open gears. This oil creates a cohesive and adhesive lubricating film that offers robust resistance to wear, water wash-out, and excessive throw-off, ensuring dependable lubrication even under demanding boundary conditions. The lubricant is recommended for all-purpose applications in open gears. Furthermore, its two lighter grades are noted to meet many builder requirements for heavily loaded splash-type enclosed gearing, showcasing its versatility. The Mobiltac Double Letter Series, which includes Mobiltac MM, has a long-standing reputation for successful use in diverse applications. Key benefits include reduced maintenance costs through longer gear life, less wear, and excellent corrosion protection. Additionally, users can expect reduced lubricant consumption due to the oil's superior adhesive qualities and resistance to being displaced, along with good low-temperature performance and peel resistance.
