    8-35%….hehhehe…

    You need to state your goals.  Question is too vague.  Maybe also list intended oils…as that makes a huge difference….even from refined to raw.  Even the choice of your emulsifier will determine how oily a certain percentage of oils will feel.  You can make a 12% oil lotion with one emulsifier that will feel oily….create a second batch with a different emulsifier….a totally different feel.  The choice of your fatty alcohol….will also change the feel or perception of oiliness.

    I have a 35% oil phase in my last project….and it is super light and quick absorbing…..change 1% of that to castor oil…..and you have a mess…

    So many variables….the heavier the oils…the less you need.  When I say 35%, that is the total of the oil phase…. emulsifiers, slip and slide ingredients, fatty alcohols, butters and oils.

    @Graillotion 
    The oils is extra virgin olive oil or coconut oil. 
    The emulsifier is Polyglyceryl-4 Laurate.
    Cetearyl alcohol or glyceryl stearate to increase the viscosity.

    I think those are some heavy weights….so keep them low….lower than 14%.  There are things you can add to decrease their heavy feel.  I have not worked with heavy oils like that….so not much help.  I use a lot of esters and light weight oils.

    @ggpetrov it will be in bottles with pump so less exposure to air.
