If you put 2-stroke fuel in a petrol lawnmower, it can cause engine damage. 2-stroke fuel contains oil, which is unnecessary for 4-stroke engines in petrol lawnmowers. This can lead to excessive smoke, carbon build-up, and fouled spark plugs, ultimately resulting in poor performance or engine seizing. For best results, always use the recommended fuel type for your lawnmower.
