My screenwash light appeared last week, so thought I top up my and the wife's cars for the winter.
Mine took 3 LARGE pots of screenwash (wow)!
But most annoyingly, I thought I'd check the oil level and the dipstick indicated less than minimum !!
Also the engine water tank was below minimum too !!
I only bought the car in August !!

It's a good thing that I wasn't hungover and that I could be bothered to check !
