Review on 🚗 Premium Automotive Antifreeze Propylene Windshield Screenwash—Ultimate Protection for Your Vehicle by Darrell Shreves

No instructions. But it's easy enough to use once you're even a little familiar with the type. I bought this to be sure to use my PG mix in an outdoor wood boiler and am glad I did rather than just trusting the mix ratio. I had to add more PG to get my desired freezing point. The scale is only in degrees Celsius, but the conversion is easy, or you can find an online conversion calculator and just plug in the numbers. Although it would be nice to have the Fahrenheit scale right in the sight glass.
