Type of fuel

I’m trying to find out which type of fuel this stove should use ?
the fuel should be automotive fuel

 

That's a Tito Landi heater, and those use either petrol or alcohol.
Both versions look the same on the outside, but differ in e.g. the size of the jet.
The alcohol version has a larger jet.

If I remember correct, the petrol fuelled versions had a natural sponge inside the tank, but I may be wrong there.
