This Saab 99 was intended to be a solution to soaring fuel prices in the 1970s: the Saab 99 petro

The dual fuel system enabled using regular gasoline and kerosene – see the separate fuel tank caps!

The car was engineered and produced in Uusikaupunki from 1980 to 1984 and sold in Finland only. Wonder if there are many around these days…

Engine modifications were relatively minor – the compression pressure was reduced by changing stock pistons to those of the Turbo model. Electronic ignition system was also sourced from the Turbo. The fuel tank was divided into two parts, 19 litres gasoline and 40 litres kerosene. Both fuels had their own fuel lines and pumps. The fuel selection was completely automatic. Many of those Petros were changed to Turbo due to the same engine construction and pistons.
