I have a turkey fryer that I have used for years. What I have used is the frying shorting you buy at Sam's club or Costco which is right by the peanut oil. I have never had a problem but you also have to babysit a fryer just like you would your smoker, checking the temp and to maintain a safe heat. It can be just as addicting. Make sure before you pour your oil into the fryer to do a dry run, put your turkey in the fryer and put water in it to see how much oil you need AFTER you remove the turkey to see the level of water it took to cover the turkey. Make a mark with something and then put the oil in, warm up and then put the turkey in. This is probably the safest way of doing it.
