In vacuum industry, people follow different practices for vacuum oil change. Normally, one of these three reasons require oil change - 1. Rotary pump starts taking longer to create vacuum or is unable to reach desired vacuum level. 2. Color of oil indicates oxidation: it changes from transparent or golden yellow to dark brown. 3. Some engineers prefer to change oil after a fixed number of working hour which are either recommended by manufacturer or are based on experience.
