Just noticed a lot of shops are still running their coolant way too rich

I mean, I see it all the time, people just dumping concentrate in the tank until it looks 'blue enough'. I was doing it too until I bought a cheap refractometer for like 30 bucks. My mix was at 12 percent when the manual for our Swiss machines says 5 to 8. We were going through a 55 gallon drum every 6 weeks, now it's more like every 3 months. The parts come out cleaner and the pumps last longer. Has anyone else actually checked their ratio lately?

Funny how it's not just about waste, the wrong mix can mess with the machine's rust inhibitors (so I've heard). You might be fine until you're not.

Skip it and find out. Seen it happen. That wrong mix eats stuff from the inside out. You won't see it coming. Then you get a real big repair bill. Not worth the risk at all.

Ngl, that's a huge waste of money.

My buddy skipped it, @betty_coleman, and his engine blew.

Honestly, is that even a big deal? I've never checked mine and everything seems fine. Feels like one of those things people make a fuss over for no reason.
