I'm using a RP filter right now.
But only because I had a coupon, maybe 2 years ago, that brought the price down to $10.
I have a few platinums on hand, but that's cause I picked them up while they were on sale.
I'd use FRAM Ultra's but since I have the other two I'm just going to stick with what I have.
But price point is a good factor in these filters. So little is published on them other than basic information and autopsy photos.
That all being said, all my engines are clean, so on any of these premium filters I run 2x intervals on the filter.
I may send off a used oil analysis and dissect a filter and start running 3x intervals on a filter, but that may take me a couple years to establish a baseline in order to do that.
I'm not driving like I used to.
