I use coolant and have a five gallon plastic bucket as a reservoir with about 3 gallons of coolant mix in it. Since I use this for flood coolant for most of my machine work, I lose a bit to the environment, so I have to top off every so often.For those that have one up and running, how much oil/coolant or whatever product you’re using, what is the capacity of your system? 1 gallon, 5 gallon, 10 gallon?
