Over the long haul, the Donaldson/amsoil is superior! Imagine what it is doing at its half life. Moreover,why even bother with the P1,why not use the Bosch distance instead,...rated at 300% capacity and 99% efficient. Yes, it costs more up front like the amsoil.
The Amsoil is a microglass depth filter, and the P1/bosch is synthetic and does not flow as well.
These filters are two different animals,with the glass being far superior!
Glass was pre-EaO which is what Synlube filter is now.
Bosch owns P1.
