Does this mean that for my purpose I could have simply used some
orinary car petrol?
Put simply, yes. Petrol is commonly used as a cleaning fluid. For
occassional cleaning purpose, it is more convenient as lighter fluid than a
2l minimum purchase of unleaded into a sealed container.
Or is lighter fuel made of a different composition to car petrol?
For the purpose intended, the differences are negligible.
