Kohler aftermarket genuine oil is engineered specifically for generator applications.
The oils are available in three formulations for different fuel types and are optimized for use in industrial, mobile, marine, and home generators. The 5W-30 formulation is for generators powered by gasoline or gaseous-fueled engines; a 5W-40 formulation is for generators powered by diesel-fueled engines; and a 15W-40 option is made for generators with gaseous-fueled engines. Each of option is formulated with a synthetic base oil that will maintain critical viscosity while also resisting “burn off,” which can occur with other, lesser quality oils, Kohler says. Special additives in the oil also help protect against engine wear and corrosion, extending overall generator life.
