Earlier this year I did my first oil change on a Prius with the cartidge filter. At the time I had used a Fram Endurance and wasn't all that impressed with the pleat spacing on that filter. The media looked like cotton, not that what it probably is. Lately I've been looking at the Mobil 1 and Carquest Premium filters. These look much more like the OEM filters which appear to be rock catchers. The media on the OEM Toyota, Carquest Premium and Mobil 1 just don't look as robust as what one would expect of a premium filter. Are there truly any advantages to a Carquest Premium or Mobil 1 in the cartridge filters for a Prius? Note that the fine print on effciency ratings usually reference a specific filter and it's not one that fits this car.
