I am aware that the BMW branded screen washer does not mix with some other brands. Evidently it congeals and blocks the washer motor. I tend to stick to the same brand, but the best option is too empty the washer bottle this time and put in the same brand from now on. The Halford's 5L blue or pink screen wash is not diluted. Seems expensive that way, so buy one that can be diluted. Pink is the premium brand at an increase cost of 50p. WOW.
Alternatively, if you are real Morgan geek, get a colour that matches the car.
