Pro tip: skip the fancy coolant additive that promises 20% longer tool life

I spent $120 on a bottle of that 'Ultra-Lube' additive after seeing the ads, and it actually gummed up my machine's coolant lines after about a week. Had to shut down for half a day to flush the whole system clean. Has anyone found a basic coolant that just works without the extra junk?

Ugh, I was a believer too until my own machine clogged.

Man that sucks, what brand of coolant were you running before the additive? I'm trying to figure out if it's just certain ones that don't play nice or if it's a universal problem.

Stick with the cheap stuff. It's all snake oil anyway.

Saw a video where they cut open a cheap filter and it was just shredded paper inside.
