The Sprinter vans have 150,000 mechanical warranty and none have died that quickly, but the filters come out at the recommended 10K oil change interval very clogged-up. So much so that you can barely see the pleats. They look more like a solid gunky cylinder. Have you ever heard of a disadvantage to a bypass filter?

Mike, no idea of why any manufacturer makes smaller filters, except possibly packaging space.
I know of no disadvantage of cleaning oil to a very high degree. Lots of fleet applications are the ones that are proponents of adding an auxiliary filter system to save money by keeping oil clean over a longer period. It also reduces down time as the only thing that has to be changed is the media (5 minutes without getting under the vehicle), not the oil.
