Review on Orange 12v 80W Oil Change Pump Extractor - Efficient Engine Oil Extraction Pump for Car, Boat, Marine, Motorbike, Truck, RV, ATV, and More Vehicles by Chad Sornsin

My Jeep dealer overfilled my Jeep Gladiator when changing the oil so I knew I had to drain 1 liter and this pump did it in less than a minute and all is fine. According to the instructions you should use the large hose in the oil fill hole but you can't do that on a jeep so the smaller hose went through the dipstick hole and it worked, just swap the hoses.
