~3750 miles with $2 QSUD 10w30 off my 1997 Blazer. This is the first filter I cut open with my new Longacre oil filter cutter. I am trying to keep the OCI's low because I believe it was neglected by the PO's and I know the LIM gaskets are failing. I haven't had to add coolant yet so that's a plus. Once they are replaced, I'll probably run a few 500 mile OCI's and perhaps a 1000-2000 then step it up to 5k.
Pay no attention to the small slit in the end cap or the small sliver of paint.
