Recently picked up a M1-110A. It is a new design (has been discussed recently on here), and to me appears to be made by Purolator. The louvers look good and are open. With purolators having a history of tearing, should I trust it? Either way I plan on running it ~20k miles, or 2x OCI, or putting it on someone else's vehicle I change oil on that would run a shorter interval.
