My car has a Goold burner set up to burn 50/50 petrol/diesel. Don't know how long our vapouriser is.

Thinking about trying kerosene in the car for a change, have been advised that it may be necessary to add some petrol to the kerosene to make it vapourise properly in our setup.

Any suggestions for trial mix - 50/50 or 1l petrol to 2l Kerosene or whatever?

Peter, if your car works well on a 50/50 petrol/diesel mix then just put the Kerosene in as it is equivalent to a 50/50 petrol/diesel mix.
