I want an oil filter with a 1 inch thick case - the thicker the case, the better!
Ok, let's be serious now - do any of us have case fatigue life testing data showing the design life versus case thickness for oil filters? Then it's not relevant to say thick = good. The design question is how thick is thick enough without adding unnecessary, wasted material and cost? Design for cost was among the many design requirements for our Design Engineers. I've never seen a filter canister fail, tear, or leak in 45 years of self oil changing. I know that doesn't mean everyone else's experience is the same, but it does mean using a quality rep. brand should minimize risk of failure.
