The best test to see if your oil is contaminated is through a micron gauge
Viscosity is a measure of the weight of the oil
Black Gold vacuum pump oil is an ISO 41, special to this type of application
Description
1-gallon bottle of Black Gold Vacuum Pump Oil. Black Gold Vacuum Pump Oil is the gold standard in vacuum pump care. For use in any vacuum pump, Black Gold is extremely pure and non-detergent. Our Black Gold is hydro processed, meaning it goes through a series of catalytic steps rendering the oil extremely refined, more viscous and more stable. The result is clear mineral oil which will alert you to contamination sooner as it becomes cloudy or milky. In extreme temperatures, the oil will be more resistant to contaminants. We still recommend, however, that the oil be changed after every evacuation for maximum performance and pump efficiency.
