Remember when you could clean the inside of your generator without lifting a finger? The WEN Magnetic Dipstick extends the lifespan of your generator by catching the loose metal filaments that naturally build up inside the crankcase. Simply replace your current dipstick with this heavy-duty aluminum alternative to begin collecting any unwanted metal shards floating around in your oil supply. The industrial-strength magnetic tip catches these deposits, allowing users to remove them from the tank by simply taking out the dipstick. The M18-2.5 threading combined with the extra-long 2.5-inch dipstick has been designed to fit WEN models 56203i, 56235i, 56235iX, 56360i, and 56360iX. This magnetic dipstick also features markings every 5mm (0.2 inches) for better accuracy when measuring oil volume.
