I'd put a pair of SS Filtermag on the oil filter and leave the stock oil and filter in place for this amount of miles:
3000 miles if you drive mostly city (driving less than 30 min each drive).
5000 miles if you drive mostly city (driving 30+ min each drive).
7,500 miles if you drive around 50/50 mix city/highway (driving 30+ min each drive).
10,000 miles if you drive mostly highway trips (driving 30+ min each drive).
An average quality oil filter (probably what you have) can remove most particles 30 microns and larger. A good quality oil filter can remove most particles 23-25 microns and larger. A pair of Filtermag SS (on the oil filter) will remove all ferrous metal particles 3 microns and larger.
That is very helpful for a new engine because new engines shed a lot of ferrous metal wear particles that are too small for the oil filter to catch, but Filtermag will catch them. This allows you to use the original oil and filter the normal amount of miles. So if there are any breakin additives in the original oil, you can benefit from them as long as manufacturer intended while having ferrous metal wear particles continuously removed by the Filtermag SS magnets.
I also think that a pair of Filtermag SS is somewhat beneficial for high mileage cars engines, but their biggest benefit is for new engines because new engines shed a lot of metal.
The 1st photo sows a pair of Filtermag SS. The 2nd photo shows a pair of Filtermag SS mounted on an oil filter. The 3rd photo shows an oil filter cut open. You can see the metal particles stuck to inside of the filter can (where where the Filtermag had been on outside of can).
P.S. - Filtermag SS is reusable. At each oil filter change, you move the magnets to the new filter.
