When should I start to use oil for the neck?

[Lentin]

Guitar arrived few days ago, and I want to clean it a bit deeper.
Could / Should I already use oil for cleaning and protecting the neck, or better to do it in some weeks?

Thanks

Once or twice a year is enough for most guitars.

What kind of oil?

I use something called No1 fingerboard oil. I have had the same tin for years. It's not sticky and has a pleasant lemon smell. I think it is a mix of oils including lemon oil. You hardly need any and wipe most of it off. I usually do it at the same time as changing the strings as Jim says, once or twice a year.

Changing strings once or twice a year... That's amazing.
After three weeks, when cleaning the strings just with a dry cotton cloth, the cloth gets black lines (I'm white and wash my hands everyday and more than once. so... easy jokes are not allowed ). So, strings get dirty.
(I use to play every day for half an hour as a minimum).
I don't know exactly how frequently I change the strings, and more these days that I'm testing different brands and gauge.

I used to apply oil when changing the strings, but that's too much compared to JB comment.

I use Dr. Duck's. It's small, but I bought it more than 5 years ago.
