If they're going to be used in an OCI which stretches 6 months or more, I feel better using something with metal end caps. For shorter OCIs they're a quality filter. Of course I have no literature to back me up on this gut feeling, it is just something that makes me feel better. I just feel as though the cardboard material could potentially start to degrade after being in use for too long.
On average I drive my Ram about 500 miles a week. This is typically all around town, lots of starts and stops. I drive 13 miles to get to work then another 13 miles to get home, while I work I typically am making multiple 3-10 mile trips. Because of this driving style I stick with Synthetic oil and a Fram TG. I change the oil and filter every 5k miles which is normally every 2.5-3 months.
The Monte Carlo gets driven a couple times a week, 20+ mile trips, for around 300 miles a week. I go by OLM which could extend an OCI to around 8 months or 6-8k miles, because of the time, not the mileage, I choose to step up the filter to an Ultra.
My mom's CX-5 has a 6k mile/6 month OCI schedule. Most of the time she reaches 6 months before she's reaching 6k miles, I'd say she's normally at 4,500-5,000. Because of the time aspect of this OCI as well I choose a filter with metal end plates, usually a Mazda filter.
