Can i use sae 30 bar oil in a lawn mower?

SAE 30 bar oil is not recommended for use in lawn mowers. While it may provide lubrication, it is specifically formulated for bar and chain applications, such as chainsaws. Lawn mowers typically require engine oil, such as SAE 30 or 10W-30, depending on the manufacturer's specifications. Always consult your mower's manual for the appropriate oil type to ensure optimal performance and longevity.
