Oil is noticeably cleaner on the dipstick. I check the level once a month and it isn't as black as it usually is when using the a.c. Delco filter. Idk if it has anything to do with the Lucas additive I run. But definitely satisfied and will continue to use these.

These are great oil filters. I have used Fram, Fram extraguard, Mobil, and K&N in the past. All these filters start getting that little drop of oil at the bottom of the filter around 5-6K miles. I'm at 11K miles on my AFE filter and yet to have a drop. I combine my AFE filter with Blue Flame Oil (15W40) by Champion sold on this site. Highly recommend this combo!
I run these filters and AMSOIL in my LMM and the oil speaks for itself after 10,000 miles. It always looks a lot cleaner then when I would have the oil changed at the dealership with GM products after 6,000 miles.
