A Little Pump Makes a Big Difference

Originally Published in MotorHome Magazine

Adding oil to an Onan generator at the end of an oil change can be excruciatingly slow. The process involves adding an ounce at a time with a frustrating pause in between. Holding the bottle is awkward due to poor access, and pouring the oil in directly from the bottle leads to small spills. I solved the problem by using a gear lube pump, which I normally use to add oil to the lower unit of my boat’s outboard motor. I bought it at Walmart for about $5. Place one end in the oil bottle, and the other in the oil port on the generator. Then slowly work the plunger to add oil in the recommended amounts. Note: Some oil bottles have different size caps and won’t accept the screw-on cap of the gear lube pump.
