Recently i am thinking of using oil lamp for my prayer corner along with candles blessed on candlemas. However, do i need to get the oil blessed before using it? i cant find any blessing for oil to be used as "oil lamp" anywhere. My girlfriend told me her parents brought along the cups that will be used for the oil lamp and got it blessed during candlemas this year instead of asking the priest to bless the oil that will be used for burning.
and do i have to use any specific oil for it such as olive oil?
