High sulphur based cutting oil. No toilet water for me, except in the
mist sprayer, which seldom gets used. Then its KoolMist.
"Lenin called them "useful idiots," those people living in
liberal democracies who by giving moral and material support
to a totalitarian ideology in effect were braiding the rope that
would hang them. Why people who enjoyed freedom and prosperity worked
passionately to destroy both is a fascinating question, one still with us
today. Now the useful idiots can be found in the chorus of appeasement,
reflexive anti-Americanism, and sentimental idealism trying to inhibit
the necessary responses to another freedom-hating ideology, radical Islam"

My favorite is BioCool 500, a synthetic whatever that means. "The Kid" got
me several pails while at a previous job. I find that the mix gets richer as
it evaporates - you're only losing water not oil. I got a coolant % tester
off eBay. When it gets over 7%, I add 3% coolant, saves almost half.
Otherwise, I add 5%. 3, 5, and 7 percent feel different; you could just thin
your adds when it starts feeling too oily.
