HEMI Oil Pressure Issues (Oil Filter Related)In a technician group, there has been some recent discussion about Amsoil oil filters causing a P1524 fault and/or cam phaser noises on late-model HEMI 5.7/6.4 engines.

That's the filter loading issue, they are telling you to avoid extended drains. The filter should still be fine for more typical drain intervals. This is what I was alluding to with the mention of filter loading earlier in the thread, but it doesn't explain the return of the pressure when he added a fresh quart.
