Understanding Oil Types for Kohler Engines
Choosing between conventional, synthetic blend, and full synthetic oils depends on your mower’s usage and environment. Synthetic blends offer better protection and longer intervals.

OEM vs Aftermarket Oils
OEM oils are formulated specifically for Kohler engines, ensuring compatibility and protection. Aftermarket oils can be cost-effective but verify API ratings and engine suitability.
