I have been noticing a disturbing trend of late in all the cars whose oil I change on a regular basis: All of them w/ the canister style filters (could be the screw on type too, but I can't see in them) have been collapsed when pulled for oil filter change. They look sort of crushed. I am wondering if anyone else has experienced this, or knows it as a symptom to a particular problem?
All of the cars are running Mobil 1 Synthetic (15w-50 or 10w-30) and using Stealership ordered MB filters. All are getting their oil changed at around 7000 miles.

Thanks for any help.....I am begining to get the fear here....cold sweats @ night and chased by crushed oil filters.....
