The formulation uses heavy-duty additives to help control oxidation, resist viscosity breakdown, and neutralize acidic contaminants that form during normal operation of lawnmowers, generators, and other outdoor power equipment. It is supplied as part number 25 357 06-S (note: replaced by 25 357 64-S), making it a direct OEM fit for Kohler engines and many small-engine applications that recommend SAE 10W-30.\u003c\/p\u003e\n\n\u003ch3\u003eWhy choose Kohler SAE 10W-30 for my lawn mower or garden equipment?\u003c\/h3\u003e\n\u003cp\u003eThis oil is tailored for small-engine demands rather than automotive systems.
