onan generator synthetic oil filter

I have a onan 5500 generator, model #5.5HGJAB-1038K.I am trying to get a part # for a synthetic oil filter so that I can run mobil 1 synthetic oil in my generator. Im hoping someone has already found a good part# and can share that with me. not having any luck with cross referances.

    For what it's worth, Cummins/Onan themselves don't recommend synthetic oil:

    Cummins does not recommend the use of Synthetic oil in Onan RV generators as there are no long-term benefits for the additional cost.
