At this price you can make up to 10 gallons of cutting fluid at a 50-1 mixture (11 ounces of oil for every 4 gallons of water). The best thing about this oil is its wide range of uses. And it doesn't delaminate like many oils labeled "water soluble." I use it in milling machines, band saws, lathes and spray guns for use on drill presses. Great cutting oil that is actually "water soluble" at a great price!
