I've seen that on some but that is not the case for all of their Classic line. If this filter shows 10k rating on the box then I'm mistaken on that part. Anyone want to check & snap a photo of this filters box to post? I live in the middle of nowhere so my options are limited.
That is to prevent bypass & or clogging as a priority for those long durations. The conversations I've had with them was what they stated was the use case with the boss extended mile filter line. Using an Advanced 20k Full Synthetic oil would be mandatory unless changing the oil mid run at 10k miles. And one point I've been stressing lately is let Fram show us their specification sheets also if they're that much better. Not that you were implying that just whats on my mind lately.
