Review on Extended Run Gas Cap Adapter With Magnetic Dipstick And Mess-Free Oil Funnel For Honda Inverter Generators - Compatible With EU1000I, EU2000I, EU3000I (Red) by Seth Waldron

I wiped the magnet after 24 hours of inverter use and the paper towel had like a fine black covering from collecting fine metal from the oil. This also may have come from the cleaning action of the Seafoam that I am using on my older model Honda EU1000 in the oil (during use) and gas at each filling. The inconsistent idle sputtering has stopped. Only using a small amount of Seafoam by following the directions. My Honda Inverter is about 15 years old. There was like a small metal shaving on the magnet that was hard to remove and the magnet did its job. The magnet sits at the tip of the dipstick and is about 3/16 inch in diameter. The magnet is a great idea and gives comfort in knowing that it is working to remove metal as there is no oil filter. I would recommend and buy this product again.
