You can use the oil again and again, using good judgment. If you clean the particles out, or even strain it, it isn't a problem. If you have fried something, that is coated with flour and the oil turns murky, of course you would want to change it. Some are saying to put it in the fridge, and that isn't a bad idea, however we never do that, nor did the long line of country cooks I come from. You can look at it and choose if you think the oil will be ok to reuse, or not. ;)
The container that the oil is in is removable, so you can easily store it in the fridge to keep the oil fresh. Depends on your taste, but I wouldn't reuse the oil if I had fried fish in it. Otherwise, I don't see any reason why you wouldn't be able to recycle your oil several times.
I bought the fryer mostly to make chicken wings, and I only change the peanut oil after using the same oil 6-8 times. Incidentally, if you decide to make wings...be sure to cook them until they all are floating at the top. Otherwise, they won't be quite done inside.
I bought this fryer last year, and love it! Usually, I use the oil 6-8 times before changing the oil. I think it's important to use peanut oil, since it has a higher smoke point.
In most cases, the oil can be used more than once. Some meats release large amounts of juices and dilute the oil, requiring the oil to be discarded. Oil used to fry fish or other strong flavored food should also be discarded. Oil to be reused is removed from the fryer once cool, filtered into a clean container, and stored in a cool place without exposure to sun light.
