I used those Purolators back in the early 80's. That's when Purolator made a quality product. Back then there were mostly Frams, Purolator and Lee "maxi filters". Sears even made decent oil filters back then.
I am having flashbacks now to days of opening cans with metal pierce and pour tools
Oh the mess they made and the cans would crimp, fold and always have quite a bit of residual oil in them
Glad our products are better these days
