I have not used a Hastings, but I do have some incidental info on them.
I was curious as to their offering for fuel filters for my Dmax, as well as other brands for that application. I emailed all the major players (Baldwin/Hastings, Purolator, Donaldson, Wix, Fram, Parker/Racor). They (Hastings) are the only company that fully and competely asnwered my questions.
They (Hastings) sent me an email that had not only clear indiciations of their origin (they and Baldwin are run from the same company and are essentially identical brand twins), but they also sent actual true ISO performance data for the fuel filter showing all ranges and particulate loading, etc. The data they sent me was run to appropriate ISO testing protocol, and even had a statement of authenticity at the bottom. Very professional and thorough. Two things I learned from this; they take customer questions seriously and they have a VERY excellent fuel filter in terms of media performance. I am impressed, to say the least.
Whether you can apply that to their lube filters is up to you. But if you email them as I did, you may well get the answer you're looking for.
