Was using Mobile, actually purchased a case of them If anyone wants to buy them I'll sell them cheap. Pm me. The reason for the change is
poor performance

. I did a test took of the filter let it sit over night all the oil drained out. To confirm this I cut open the and all the was gone

.
I had some cam chain rattle that I never had before.

New batch of filters? I put on the Bosch filter changed the oil. No rattle, higher oil pressure

. I took off the filter did the same test oil remained in the filter as it was suppose to

. Did some further reasearch I found the mobile1 filter is actually made by Champion. That explains that....
Use what you will as this is only my opinion and observations I made.
