I am wearing a 8165. But when u are mentioning kiwi, do you mean those which use for saf no.4 boots???

Pls don't ya... It will "kill" the leather...
For me, I have only been using the cheapo mink oil easily available at bata for less than $10. Start wearing it first for a few mths, no need care abt the oiling part coz usually the shoes itself should have been coated liaoz. Then along the way as u notice the leather starting to be a little creasing le (usually 5-6mths), u can slap a layer of those oil and massage in with your fingers. I read that its better to use fingers to rub in than use cloth coz of the heat. Go into every corners, and then let it dry naturally.
Thumb of rule, don't be too nice to your RW. Trash it well, and it will return beautifully.
