What type of fuel should I utilize in my lawn mower to ensure optimal performance and longevity? Is regular unleaded gasoline the preferred choice, or should I contemplate more specialized fuel formulations? Given the variations in engine types and designs across different mower models, how does the required octane rating influence engine efficiency and cutting power? Furthermore, in an era increasingly focused on environmental considerations, should I be considering alternative fuels such as ethanol-blended gasoline? What implications does using such blends have on the equipment’s internal components and overall maintenance? Are there specific brands or formulations that have garnered a reputation for enhancing mower performance? Should one be wary of using old or stale gasoline, and if so, what are the telltale signs of fuel degradation? In the pursuit of optimal mowing results, how critical is it to adhere to manufacturer recommendations regarding fuel specifications? What best practices should be followed for fuel storage and handling to avoid complications?
