Oil usage/burning on new Subaru


Asked by Dec 17, 2014 at 05:42 PM about the 2014 Subaru Outback

Question type: Maintenance & Repair

I have a 2014 Subaru Outback. It has 8000 miles and is ready for its first oil change.
However, a week or two ago the oil light came on and it needed a quart of oil. I have a
1988 Mercedes and it does not use a quart of oil

There's a Subaru service bulletin out there, see below, hope this helps. Oil control piston rings is the root cause The excessive oil consumption problem appears to be with "unanticipated wear of the oil control piston rings as the root cause of the oil consumption defect." Subaru is aware of the problem and says all of these affected models should still be covered under Subaru's powertrain warranty. If you own a 2011-2014 Forester, 2013 Legacy and 2013 Outback, with a 2.5-liter engine, and 2012-13 Impreza and 2013 Crosstrek, with a 2-liter engine and are experiencing these oil consumption issues, you can contact your nearest Subaru dealer for more information. http://www.torquenews.com/1084/subaru-sued-over- excessive-oil-consumption-your-car-list

Isn't the first oil change supposed to occur earlier than 8,000 miles? How's your car holding up?


As a point of information, not all newer Subaru cars burn oil, see this, http://www.subaruoutback.org/forums/138-gen-5-2015-present/221146- oil-consumption-survey-2015-a-4.html


I have a 2014 Impreza and the same thing happened to me when I had just bought it. Just happened to me again at 31000km. Not happy.

Not Impreza 2014 and Jack Carter- are your cars manual transmissions or automatics? Just curious.

Markw1952... I guess you do not remember your internet lecture to me about how superior automatics were to my standard transmission...?


No, sorry, so many threads on this forum. Enjoy your manual transmission, hope it works well for you. I've just had too many negative experiences with them compared to automatics and I learned how to first drive on manuals and had plenty. Two cars, with over 100,000 miles each. One transmission went out and the other one needed a clutch replaced. All very expensive mechanical work. I'm just saying that, I've had better luck with the automatic transmissions.


If your car went 8,000 miles and only used a quart of oil then you have a good one! Mine is using about 8x as much! You should be changing it every 6,000 miles though.


My car used a small amount of oil once while pulling my trailer in Sequoia Kings Canyon up the mountain pass, pretty steep road. Otherwise, I don't see any consumption. I'm talking less than a half a quart. It was extremely hot as well. I'm sorry to hear about your problems and would advise you to contact Subaru of America, and your dealer for the oil consumption test. The problem is with the newer designed engine, the FB series. My car has the older EJ 25, phase 2 engine.


JACK, Ignore the other comments. The problem is that Subie's switch from thicker dino oil to ultra-thin 0w synth can't stay in the horizontally-opposed pistons that "wobble" when warming up. Your story is a repeat of many since 0w20 synth was introduced. Aside from SOA new car recourse, I strongly suggest you switch to 10w30-40 dino oil, and check it MONTHLY. Change it every three months, regardless of mileage, as it gets dirty from cold starts, not mileage or time. But if SOA thinks your rings are actually "defective" then get them to give you a new motor...or at least a block carefully glued to your heads. Push SOA hard if you have to.
