Most likely not, we’re already having trouble with adblue (basically just urea) freezing, especially in the northern parts. There was recently some piece of news where a repair shop in Lapland was up to their neck in repair orders for emissions control systems due to frozen adblue liquid.

Practically all washer fluid sold in Finland uses some alcohol as the deicer, typically just your normal denatured ethanol. I’d also think having urea in the washer fluid would wreak absolute havoc on some parts that get exposed to it – I’m under the impression that it’s quite nasty stuff for many different materials.

I could say precisely the same about standard pencils – you have to constantly be sharpening it if you want properly dense handwriting. Mechanical with .2 or .3 and you don’t even have to rotate it to get a sharp edge.

1st one, with either .2 or .3 lead. That also happens to be what I main for writing already.
