Our company is now playing with the thought of using raw coolant in the place of waylube. We run 14 machines off of a single tank colant system. All the waylube and hydraulic fluid gets into the system making them cycle out the collant more then they would like. They figure if the use raw coolant instead of waylube then they would only have to add water to the tank and be able to go longer without cycling out the coolant in the main tank. this would save money in buying way lube and save money by not having to replace the coolant. Im kinda stuck at the idea that raw coolant ins water soluable and will mix in and get washed away. Therefore not really doing its job.

Thoughts??
