Until what age do you usually put oil to your baby before bath time?

When my baby was discharged, my pedia had a list of products to avoid using on baby and baby oil was one of them, my little one is now one year old and 3 months and up till now, we have not used baby oil, baby powder, cologne and lotions on my son. The only thing we have used so far are organic insect repellents. I would say it didn't have any negative effects when not using them and it saves up budget on toiletries.
