I've noticed that different machines use different types of (crude) oil. The type of oil usually corresponds to the type of oil the machine originates from. However some recipes are edited - such as GregTech oil distillation which accepts oil from Ad Astra.
Oily Bees are even more confusing since (according to JEI) oily combs can be separated info different types of oil.
It would be really helpful if all types of oil (maybe excluding GT) would be unified into one single type of oil to support mod-cross-compatibility.

EDIT: I double checked and saw that the tag "forge:oil" is only supported by GregTechs Oil and Ad Astras Oil
