For those who are willing to buy Toyota oil filters in quantity, note that you can buy a case of 10 for $3.29 each (plus shipping). Champion ToyotaWorld Toyota has more incentive than any aftermarket oil filter producer to produce a quality filter, since Toyota is the entity which bears liability for the powertrain warranty.
i am running Mobil 1 oil and filter. I suggest buying the oil and filter "where ever" and pay the dealer or whom ever the labor to make the change. it cost me $17 at the dealer if i supply the oil and filter.
