I was planning to use the Fram PH8A as an initial startup filter with hi-Zinc break-in motor oil... figure ~2-hours max (flat tappet, hyd)... then change the springs, etc... and then throw away that Fram PH8a for a better filter... racing PH1 or other as I've always used throughout the season..

Any opinions on just using the PH8a as a quick break-in then throw away filter?
