This is where Nick can tell you the differences but I know that they are just recommended for different drain intervals. Amsoil does make a filter that is about twice the price as the Wix but it is meant for 15000 miles or more. Its all 100% synthetic.
I am speculating that they dont make just one great product because of people like yourself that are uncomfortable with a long drain interval. I assume that they have different additives to make the oil last longer.
