So I weighed a gallon of -25F wiper fluid and it is 8# per gallon (actual weight of fluid excluding the container).

If we believe the MSDS is around 33% then it is ~50 oz of meth per 128oz of wiper fluid which is 33.65% by WEIGHT and is 39% by VOLUME. My plan is to displace 24 oz of wiper fluid with 24 oz of HEET which will get me 57.8% by VOLUME or 52% by WEIGHT. These are rough calcs but I believe they should be about right. Cost about $7/gal which is $3 less than buying boost juice.
