Default Water/Methanol Injection FAQ

Hey guys. I noticed that washer fluid msds is measured methanol by weight not by volume. -25F is usually around 34%. So my question is what VOLUME of pure methanol does it take to get it to 50% by weight? Assuming boost juice is 50% by weight not volume. Meth is about 6 lb per gallon and water is more like 8. I was thinking adding 24 oz of pure methanol per gallon(removing 24 oz of wiper fluid from the bottle first) would be roughly the right spot but that is going by volume. Doesn’t need to be perfect but I need significantly more knock resistance than wiper fluid is giving me.
