No, you don't even have to know that they are words. Call them icons if you like. The pipe from the pump marked DIESEL and coloured 'whatever' goes into the car with the cap marked DIESEL and with the same colour and smell. It doesn't take much thought.
Does the colour of the pump handle match the colour of filler cap for all petrol/diesel cars currently in production? My car's filler cap is black and the pump handle I filled up with this afternoon was green. As for the smell, I was seriously unaware that diesel and petrol smelt different (shows you how much exposure I've had to diesel machines).
