How much FO should you add to 32 oz oil batch
Probably between 2 and 3 oz. But some FOs have a higher usage rate, and some have a lower. Check the vendor's website.
ETA: 32 oz total or 32 oz oils?
Hi Allen....it really depends on the particular FO and its suggested usage rate for skin safety, so I would first check with the supplier of where you bought it. Most of the ones I use are safe up to 6% ppo or higher, but I usually use the least amount I can get away with and still have my soap smell good for a long time, which is usually 5% ppo, but some are so strong that I can go even lower (2% ppo). For what its worth, I never go over 6% ppo on the FOs that say I can if I want to. They tend to weep out of the soap when used much higher than that.
32 oz oil
Allan, it depends on the supplier's recommended maximum usage rate.

The BB calculator uses weight of oil + water, vs some (such as Majestic Mountain Sage www.thesage.com) that use just oil weight. I cheat a bit here - even if my FO isn't from BB, I'll use their calculator. For example, most vendors have a Dragon's Blood FO and I figure the components are close enough that I can use BB's calculator for it. If they don't have a match, I'll use something similar - Apple Pie FO and Apple Strudel FO are probably pretty similar. Ideally you look on the vendors website, but if it's a discontinued FO that info might not be available.
