Can you drive with a bad vacuum pump?
Should you drive your car with a bad vacuum pump? No, not really. Your vacuum pump is responsible for the proper operation of many of the key systems in your car, most notably the brakes. A bad vacuum pump can also disable your defroster, heating, and air conditioning systems.
How do you test a vacuum pump?

How do I know if my vacuum pump has a vacuum leak?
One of the most accurate methods of vacuum leak detection is the helium leak detector. A sensor is usually placed near the inlet to the vacuum pump to detect any increase in helium concentration in the air stream. Helium is then sprayed on any potential leak points in the system or piping.
Why is my vacuum pump not pulling vacuum?
Putting in the incorrect amount of oil, putting in the wrong type of oil, and oil contamination can all cause the pump to not reach full vacuum. If you find that the pump’s oil is dirty, you should flush it and refill it with new oil.
What will happen if dirty oil is left in a vacuum pump?
Contaminated oil will block the oil mist filter and raise the working pressure inside the pump, ultimately overloading the motor (and possibly rupturing the oil mist filter if it is very badly contaminated).
How long can a vacuum pump run?

Can I leave a vacuum pump running overnight?
As the pump pulls high volumes of water vapor out of the system these vapors can condense inside the pump eventually displacing the oil and ruining the pump. Allow the vacuum pump to run overnight without supervision only after a visible inspection of the drained vacuum pump oil reveals little or no moisture.
What kind of oil can you use in a vacuum pump?

Why should you change vacuum pump oil?

What is special about vacuum pump oil?
Vacuum pump oil is essential in keeping your vacuum pump operational. It lubricates the pumping machine, while also collecting contaminants and moisture from the evacuated systems. These application-specific oils should be pure from additives, (apart from anti-oxidation, anti-foaming, or corrosion-resistant additives).
How do you dispose of vacuum pump oil?
Vacuum pumps must be stored on spill trays to prevent oil spills. Vacuum pump areas may be insulated for noise, if necessary. All used vacuum pump oils must be dispose of through EH&S. Do not dispose of chemical wastes by dumping them down a sink, flushing in a toilet or discarding in regular trash containers.
