Make sure the area where the o rings go is clean. If it is, try another filter.
When I worked at a quick lube, standard practice was to just replace the big o ring on the cap. At the time, few cars had cartridge filters aside from BMWs, and 99% of the cartridge filter cars we serviced were BMWs. We never replaced the small o ring, only the big one on the filter's "cap." We never torqued down the bolt, snug always worked. I don't remember any of those cars ever coming back for a problem.
snug is way I tighten-never torque. Replace the small o-ring every time becasue itit there and I am working on my car.
I completely agree, and if I were my own car I'd always replace the small o ring...but at the quick lube spending an extra couple of minutes messing around with the small o ring would get you yelled at, so it usually just stayed where it was.
