US 2015 CRV EX (2.4l Earth Dreams Engine).
The image shows oil (or maybe just dirt?) on my last filter with ~20K miles on. At ~30K miles I swapped it first and that one was far worse.
Before this filter went in I swapped out the PCV valve (quick/easy task).
I did manage to push a trombone brush quite far down the PCV hose and it was clean. Since then I bought a longer/ thinner brush but have not had time to get to the PCV hose .
Has anyone else seen this? Swapping the Engine Air Filter every 20K miles I don't mind, assuming no damage is happening.
The CRV is near perfect otherwise. Swapping out the transmission fluid for Castrol Transmax made the CVT super smooth (done over 20K miles ago). Just regular maintenance otherwise.
