“Emptied my washers tank so it isn't diluted with anything else. Made up a 25% solution using pure water and so far so good. No problems clearing the screen and it appears to cover a larger area on the screen as it hits before the wipers take over. I can't see that I need to make it any stronger than 25% which is down to -10 for my location, never gets down to that. I've used other Motul products in the past such as oil, brake fluid, coolant, gear oil and never had any concerns.”
