Have just changed out the initial fill and filter from my new Toyota Corolla. The filter fitted at the factory is part no 909151003 and the filters sold at the dealers are part no 90915YZZE1. I queried with the dealer who confirmed the filters I had bought were ok. The filter fitted at the factory was of a quality the better of which I have never seen, looked much better than replacement. I am now wondering if I should have left in the initial oil fill to be filtered by this seemingly super filter until the specified 10k kms service.
