Fram uses:
1. “cardboard end caps” You obviously haven’t ever changed a cartridge type filter....ALL of them have paper end caps. Bottom line...not an issue.
2. “rubber anti-drainback valve seals the rough metal backplate to the cardboard end cap and easily leaks, causing dirty oil to drain back into the pan”......Take a look at where a Chevy oil filter is mounted. It’s mounted LOW. Oil cannot drain back into the pan. Chevy cartridge oil filters don’t even have anti-drainback valves. Bottom line...not an issue.


You can compare different filters by their looks till the cows come home but that really doesn’t tell you anything. The only real way to compare filters is by oil analysis. Show us multiple unbiased oil analysis showing the Fram filters are inferior and then the world will be convinced.
