Johnson Pump

Johnson Pump manufactures dependable marine oil-change systems that make routine engine maintenance faster and cleaner. Its lineup includes durable, self-priming models that use either run-dry PTFE gear technology or high-capacity flexible impellers. Both designs extract used engine oil through the dipstick tube and connect to a 12-volt battery with heavy-duty leads.

Key Buying Considerations

·         Pump mechanism: Choose a PTFE gear pump if the unit may occasionally run dry or if you work in colder conditions, where oil becomes thicker. Choose a flexible impeller pump when speed is the priority; it delivers a substantially higher flow rate—5.5 GPM versus 2.1 GPM—but should not be operated completely dry.

·         Container convenience: A kit with a 5-gallon bucket creates a contained, cleaner work area and includes an easy-pour spout for neater transfers when recycling used oil.
