    Just changed my oil, and checked my air filter while there. I has horrified to find the element(original airbox) was almost black from being oily and dirt sticking to the oil after about 8-12k miles) Knowing that an oil bath air filter hasn't been standard equipment on a Ford since the 50's, I was concerned.

    I took the element to my dealer service writer, and after first trying to send me to the parts department where I could buy a new filter, when expressed my concerns about it, he immediately told me it was normal. Didn't ask what kind of car, etc. Just asked if it was using oil, and I said enough to be below the hash on the dipstick after 8000 or so miles. His answer was "we recommend 5000 mile changes on oil, at which point I told him, I let the car tell me when oil life is down to 30-20% and he just repeated his we recommend speech.

    Has anyone ever experienced oily air filters? Is it normal on our cars? I've been irritated by oily exhaust tips since I have owned the car, but now I am also concerned since my 140,000 mile 11 explorer doesn't soak the air filter with oil, why is my 29,000 mile SHO doing it?

    I guess my biggest pet peeve is the condescending tone in which he told me it was normal...like as if to say, go back to your pushrod 5 liter, cause you are not smart enough to understand Fords today...

    Sounds like a problem with the PCV system, perhaps a bad PCV valve/oil separator issue, since your 2015 should have the updated valve cover already. Look there, look in the intercooler, and in the turbo piping to see where else the oil is showing up.

    You should have soot on the exhaust tips, not normally oily though. Hmmm.

    DEF NOT NORMAL.

    You could bring it up to the service manager. You are corrct the there only published oil change interval is 1 year 10,000 miles by the owner's manual or when told my the intelegent minder (if it was properly reset). Their recommndation is null unless you fall into special operating conditions.

    Isn't the air filter 30K maint? It was time to replace it but I can see what their would be that much oil in the air box as SHODDED mentioned. The oil should be consumed by the engine not drain unto the box.

    I've never seen even a drop of oil on the air filter of either of my SHO's. I would ask to talk to the service manager or find another dealer altogether.

    I do get some oil residue on the filter closest to the intake tube. I follow the oil life percentage in the car but don't go over 5000k miles anyway regardless. Car has about 45k miles and no other issues.

    I would take a look at the PCV valve/oil separator anyway. Not that expensive/difficult to change out.

    What side of the PCV system is the oil separator on. I though it was on the vacuum side not the pressure/boost side?

    I' just thinking if he is getting oil on the clean side he has to much blow by, the P.C.V. valve is not closing preventing boost from entering the crankcase, or the P.C.V. valv is stuck closed and all crankcase pressure is going into the fresh air system.

    What gets me is we have a sense for this that should set a d.t.c..
