Does anyone who has a meth kit use the PEAK window washer and deicer fluid. Its a blue bottle. If so what negative degree do you use -20 or -25. trying to figure out if this stuff is ok to use.

this is what my local stores have.

It technically is the same stuff but I don't know a single person who'd risk putting it in their motor.
