Our 2012 Outback has consumed oil excessively since the day we got it. (excessive = 1.3 qt/1200 miles) This is many times more than any car we or any extended family have ever owned, which is dozens of cars and at least 10 manufacturers. The dealer has insisted that "up to 1qt/1200 miles is normal and as-designed. Lousy design.
I don't know if they ever checked the PCV or rear separator plate (I'll ask tomorrow), but they now have offered the following: "We will install a new valve cover, inside of which there are a series of baffles. These keep the normal oil inside the of the valve cover from getting to the PCV valve, but Subaru has found some oil getting past one of the baffles allowing the PCV to pick up the oil. The new valve cover is supposed to keep that from happening. The new part number is 13728AA291"
I don't know if anyone else has experience with this, but I'm interested in any info.
Is your Outback the 6 cylinder model?
My family's 2011 3.6 has been burning oil lately, but usually only under stress: i.e. two road trips with the car loaded.
They had showed a (I believe valve cover plate) and how dirty it was, whichever piece it was, they insisted it had tiny channels for some sort of valve that can get clogged up.
Now that I think about it, it was to the Crankcase, so PCV it must be.
On two occasions, the head mechanic pulled one of these clogged plates from a pile lol, and spewed what we took as rubbish.
They insisted a "proper" oil maintenance schedule should be followed with something like once every 3,000 miles for these 6 cylinders. Otherwise the plates get gunked up and you know the rest, as for simply reconditioning/cleaning the plate, I was told and shown by the mechanic that's been there for years, that it's quite impossible to clean, and the channels are riveted into the plate... non-removable by their standards.
What I took from this, is the covers do have a pseudo-design flaw, we have been adhering to their oil schedule just to ensure warranty coverage, 5k is what we went with for the first few oil changes (besides the very first).
Hudsonfamily, my family just drove to FL from the midwest and had the car checked at a dealer down there. I'll find out how "our's" is doing, but above all else, KEEP BUGGING THE DEALER and get as many records of these issues as you can early on.
That's what they're doing.
