The question is why, lol
"...the Trabant 1.1 produced 1990-1991 with a 1043cc VW engine (making the "1.1" a slight misnomer). The engine for the Trabant 500, 600 and original 601 was a small two-stroke engine with two cylinders, giving the vehicle modest performance. At the end of production in 1989 it delivered 19 kW (26 horsepower) from a 600 cc displacement. The car took 21 seconds from 0 to 100 km/h (62 mph) and the top speed was 112 km/h (70 mph). There were two main problems with the engine: the smoky exhaust and the pollution it produced—nine times the amount of hydrocarbons and five times the carbon monoxide emissions of the average European car of 2007. The fuel consumption was 7 L/100 km (40 mpg-imp; 34 mpg-US). Since the engine does not have an oil injection system, two-stroke oil has to be added to the 24 litre fuel tank every time the car was filled up, at a 50:1 ratio of fuel to oil. Owners normally carry a container of two-stroke oil in the car for this purpose. The earlier models have no fuel gauge; a dipstick is inserted into the tank to determine how much fuel remains."
