In my 13' LML, I used to only use Fram Ultraguard filters, then Mobil1, then K&N, but they always started to leak a bit after 3-4K miles. These AFE filters are great. I've done 3 oil changes with these filters and I've been amazed at the fact I never get that small drop of oil on the bottom of the filter. Plus my oil seems so much cleaner. I use Champions Blue Flame 15w40 SynBlend and when I go to change the oil, it still has a small amount of blue tint to the oil. Rotella would be blacker than black when the oil would be changed and it would be somewhat thick when combined with those other filters. The Blue Flame paired with this AFE filter leaves the oil smooth and clean.

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!
