With this I did my first engine oil change DIY and pretty happy with it. I wanted to change engine oil By myself, but don’t want to go under the car. Fortunately, my car oil filter is on the top so I won’t need to go under the car if I can extract the oil. The pump worked very well, very easy to use and the dispenser function useful. The clean process took a bit time, but not too bad. I have no comparison with other products’ cleaning process. Recommend it
