Review on Atima Magnetic Dipstick Oil Change Funnel: Perfect Fit for Honda EU1000i, EU2000i, EU3000i Handi, EU3000is Engines by Don Devine

Works great. It's good to know that the magnetic plug captures any metal fragments that might get into the system. The drain hose was not leaking. The only issue I had was that you can't see when the oil level is full until it starts filling the drain hose. But it's easy to drain again by tipping the generator over with the drain hose attached (no big deal).
