The oil filter can hold so much. If the engine is filthy ... even the Amsoil EaO filter has it's limitation.
I'll be dead serious as I used the Amsoil HDD 5w-30(with ARX) and my engine saw but Amsoil 1,000 - 120,000 miles. My engine was very clean(I'm anal) but from design issues I developed a slight sluggishness and wanted that corrected.
I ran ARX for 8,000 miles and looking back it may not have been necessary but I'm not the one to say it just happened maybe I was clumsy. I don't thing I would have run that many miles on a dirty engine(an oil filter is small because of more efficient engines developed). None the less the oil filter in the cleaning phrase was very heavy, very noticeable. The rinse phrase zip there was nothing. On my next run with Amsoil with the EaO filter after 12,000 miles again the filter had zip nothing in it.
I did my one time treatment with ARX and I appreciate what the product has done for my engine. The engine is back what it had originally been on Amsoil with the EaO filter for 12,000 miles yearly.
