It takes about 1.3 bottles to fill it above the min fill line, so you get a little extra oil. Once you fill it you need to keep the pump upright to prevent the oil from spilling, and when you turn it on the motor vibration makes a little bit of oil sometimes escape the top of the vent hole. So if you are looking for something to use in a clean environment, better buy an oil-free model. It is loud in operation, but gets the job done. It pulled a good vacuum and held it as long as I needed. It has three different hose connection options, and the two that you are not currently using are sealed by the red plastic caps with included o-rings (but sometimes the o-rings will stay on the nozzle, instead of inside the cap, so you have to be careful to not misplace them).
