I can't remember the filter number off the top of my head, but the two quart big truck oil filter is really nice and happens to fit quite a few car chassis. It's actually easier to change due to it's length and you can never go wrong with an extra quart of insurance on your investment. As for the smaller filters, the AC PF35L is the same size as the regular PF35, but is composed of a high tech synthetic filter media inside instead of the standard paper inside. As for oil, Mobil One synthetic is the only one that exists in my world. It was first, it is best. There is nothing else. Buy it by the gallon at Wal-Mart.
