Review on 🚤 12V 80W Electric Oil Pump with Handle for Oil Change - THINKWORK Marine Oil Change Pump and Extractor for Boat, Car, Motorcycle by Brian Kumar

I used this to change the oil on my boat. Worked great as described. Warm up the engine for 5 minutes and add 4 liters of 10W40 in about 6-8 minutes. I inserted the suction hose into the dipstick tube and removed the filler cap during use. A boat oil and filter change costs $199 and up. This item paid for itself after one use. Not sure how this thing will hold up given its noisy operation, but the suction was very good and it was easy to set up and use.
