Greg,
My own experience indicates that paraffin (also known as paraffin oil) is the same as kerosene and lamp oil.

I know of no seperate substance that is called paraffin oil.

The viscosity of paraffin oil is 1.... which is exactly the same viscosity as kerosene.

Ugo quotes an sae of 15 - 20 for paraffin oil and an sae of 1 for kerosene..... something is wrong here.

Having done a quick check online I found all references to paraffin oil were in fact refering to the paraffin oil which is the equivalent of kerosene.

I wonder.... is there an "up cock" in the MVVS instructions or, are they refering to something which is NOT generally known by the name of paraffin oil ???
