Naphtha once was in competition with kerosene as one of the three main ingredients for model engine diesel fuel. Way back in 1947 and so on there was a lot of debates over which was best for the model diesel fuel.
Naphtha is used as lighter fluid here in the USA too.

I saw references to Petrolej being lamp oil, so it ought to work. You want the unscented version with no aromatic additives.
