How much washer fluid to refill after low warning?

[Wineeeee24]

Hi everyone! I just go the washer fluid low warning. Do you know how much fluid is needed to refill the reservoir? Stupid question, I know! But I am asking it because I use concentrated washer fluid. Knowing the exact volume would help me mix it properly. So, does anyone know the refill amount or how to measure the total capacity of the reservoir?

The volume of the reservoir is around 7.6 US pints. I hope it helps! What kind of washer fluid do you use?
