Their cross for a Mobil 1 M1-209 is a PH3600 when they make a cross for every grade of filter they make. Someone running a Mobil 1 filter might not be interested in a PH Fram filter.
All you have to do is substitute TG for Tough Guard and XG for Ultra. We cannot make a cross ref for every single filter in the market and it is much better and more accurate to look up filter parts numbers by year, make, model and engine size. Then they are recommended by OCI in our catalog online.
