I found the easiest way to get the correct amount of oil in the turkey fryer is as follows.
The night before you cook, put the turkey in the pot and then fill the pot with water until you get to the proper level. Then remove the bird and measure how much water is in the pot. That is how much oil to add when you get ready to cook.
I do this the night before to make sure the bird is dry when you get ready to cook. Dropping a wet turkey into hot oil is something that you do not want to do.
