I broke in an engine/cam one time with an orange FRAM filter. Internally the filter literally crumbled in like a pop-can due to increased pressures with the break-in oil/lube, etc. Those filters are JUNK. I wouldnt put one in my lawn mower. I got lucky and had no damage with this one. After that I started using WIX filters (avail at NAPA) exclusively in all my vehicles. I believe all the NAPA gold filters are WIX. I dont have much experience with the STP filters.
