In Germany after 1927, Motalin was a gasoline that was sold by Deutsche Gasolin AG and made a “compression-resistant fuel” by adding iron pentacarbonyl . The basis was petrol or mainly the synthetic Leuna petrol produced by IG Farben in the ammonia works Merseburg - Leuna Werke from coal through coal liquefaction . It was developed by the chemist Walter Ostwald , who worked as a freelancer for IG Farben in the late 1920s.

The use of Motalin could be recognized by the spark plugs and combustion chamber, as a red iron oxide layer was deposited. Therefore, the use of Motalin was later abandoned.

From 1928 on there were small metal canisters with a concentrated mixture of iron carbonyls as an additive to increase the knock resistance (so-called motyl cartridges ) for pure gasoline, which thus received properties similar to Motalin.

Depending on the amount and concentration of the addition, octane numbers of over 90 RON would have been achieved, roughly corresponding to the improvements as with lead tetraethylene .
