I was running my coolant way too rich for years without knowing

Had a job last week where my finish was just off, like a haze on the aluminum. My buddy from the shop in Dayton asked what my coolant mix was, and I said the usual 10 to 1. He told me to check it with a refractometer. Mine was reading 12%, not the 5% I thought. I'd been eyeballing it forever. The haze cleared up instantly when I got the mix right. Anyone else have a simple tool they started using that fixed a dumb mistake?

Eyeballing it forever" is the real killer. A refractometer is cheap but that's not even the point. The real fix is just admitting you need to measure things.

Honestly @felix414 is totally right. You see it all the time with people trying to mix cocktails or even bake bread. They just keep guessing and the results are never the same twice. Tbh it feels like a weird pride thing, like measuring is cheating. But grabbing a simple jigger or a scale just makes everything work the first time.

Classic case of thinking your eyeballs are calibrated instruments. That refractometer just proved your gut feeling was a straight up liar. Bet your wallet's happier now too, not wasting all that concentrate.
