How Do You Know When It's Time to Change Your Vacuum Pump Oil?

There are two main ways to gauge whether or not your oil needs to be changed.

1. A good indicator of when to change your oil is the color. In general, it should be light, but there is a range of acceptable shades at which your pump will function. If you’re checking the oil in your vacuum pump, match the color to the resource provided below.
