I did a search for oil filters and spend time trying to find a answer about the difference in filter grades. I hope this does not start a “war”. I am a Fram filter user for over 35 years. I bought a new 84 Corolla, changed the oil Non synthetic) and filter every 2500 miles (half the recommend mileage). Over 13 years I put 325,000 miles on the car before selling (rotted floors). Use whatever filter type you want.
I know have been using synthetic oil (Mobil 1) for about 20 years now. But now my 2019 Camry requires 0W-16 grade. Since I still change at 5000 miles (half the mileage recommendation) I am getting concerned about the actual filter. I typically use the Fram Extra Guard or Tough Guard (depending on which one is in stock). Fram also has the Ultra Synthetic.
On their website Fram the Extra Guard is 95.7% efficient @ 20 microns using the ISO test. But also mentions a filter should be able to handle 10 microns. This implies the newer engine might need better filtering.
I could not find the same information for the other filters. Does anyone have this information or where to find it? It the Ultra Synthetic that much better in my case?
