Ratio of Oil to Fuel in Lampe Berger?

I have the Lampe Berger real oil in ocean spray. I have made the cheap version of the fuel using the 16 oz. bottle of 91% isopropyl and 1 tablespoon of distilled water.

How much of the Lampe Berger real oil should I add to my homemade fuel?

( I have added 1/2 teaspoon, but it barely scents the room )

Thanks!
