I recently bought a STP oil filter (no. S2995). Today I was in the store where they had a sale on Purolator filters. After coming home, I compared the two and noticed that the Purlator (no. L30381) was taller by about a half inch. The filter and gasket diameter are the same.
Won't you have less filter surface area if the filter is shorter?
