The Honda eu2000i has a ridiculously small protrusion under the oil plug which is designed to drain oil without getting into the generator or onto the garage floor. This has always led to confusion. I finally bought one of these extensions. Made of flexible plastic that threads fits, doesn't leak. Seriously reduces the mess when changing your generator oil.
