I'll concede that point, although I used to run MC FL400S filters for 10k intervals on my old Taurus. I don't see why an FL820S won't do at least the same, provided the engine is healthy.
*Clarification* I don't mean to imply the Ultra is not a good filter. I think FRAM finally got it right this time, but it's still overpriced.
