A vacuum pump oil can cost anywhere from $5 to $25 per gallon, according to a recent Consumer Reports study.
To get the cheapest price, you could use a pump from Costco, the company that supplies oil to vacuum cleaners.
The pump costs about $1,000, according the company.
Costco says the pump will run for two weeks, and the pump can be easily replaced.
The company says the oil comes from a company called Whirlpool.
But a WhirlPool spokesperson says Whirl Pool supplies the vacuum pump and other components for its products.
Costco does not offer an exact cost, but said it charges $10 per gallon for the pump.
WhirlPowers says its pump can supply vacuum cleaners with up to 100,000 gallons per minute.
That can run for several hours at a time, or longer.
