As the title says, the oven does not take Pam's HarvestCraft 2 cooking oil or any oil as fuel, even if "Oven Requires Cooking Oil"=true. I am using the four PHC2 mods for 1.16.4.

This can be replicated by placing an oven and filling it with raw chicken, for example; the fuel slot takes coal but does not allow me to place a jar of oil.
