In practice, it doesn't make a huge amount off difference as petrol contains a mix of aromatic and aliphatic molecules anyway and adding 330ml to a 65L tank is only 0.5%.
Paraffins to a Chemist have a specific meaning i.e. alkanes: saturated aliphatic molecules, but I very much doubt that that is what you get in the can!
At an oil refinery, crude oil is separated by boiling point in fractional distilation columns, C5 and below will be aliphatic and the percentage of aromatic molecules will increase with increasing Cn. therefore, from the same batch or crude oil, Naphtha would have a greater aliphatic content than Kerosene. But unless it's further refined it will still be an aliphatic/aromatic mix of some sort.
So to save confusion, Naphtha, Kerosene, Paraffin and unless there's anthing else in it that I don't know about, White Spirit are basically the same and should do the same job.
