A remark about the Trabant, quote from the Wikipedia article "[...] as even refueling the car required lifting the hood, filling the tank with gasoline (only 24 litres[1]), then adding two-stroke oil and shaking it back and forth to mix."
This isn't correct, in the GDR each petrol station had petrol that was prepared for the Trabant, there was no such thing as mixing the two stroke-oil and shaking, that is absolute nonsense (it is kind of true if you have such a car nowadays since petrol stations stopped to sell two stroke fuel).
