This supply of Lube King's multi-purpose gear lubricant is designed to deliver protection against spalling and other forms of wear, especially under extreme heat conditions. It maintains viscosity, providing for a longer fluid life and extra resistance to thermal degradation, oxidation, and deposit formation. Doing so ensures a longer life for your equipment and therefore reduces operating costs. With the 5 gallon size, you'll have some on hand in your shop, preventing time consuming trips to the store. | Lube King 85W-140 EP Gear Lubricant | Size 2 gal
