Original oil filter at Toyota Prius Oil Filter , is fine. I have used it several times and had no problems. Don't buy DEU, I didn't like it, it leaked in winter. Last time I used ACDelco filter, no problems.
I've used almost 8,500 on this filter. I am going to change it again soon... I bought everything, but this time I decided to try Mann filter. I have always used original fluids, no problems with them.
