Idk, I'd think if there were a bias, it would be the other way. Being that newbies (ie-googlers) can't vote and this is an "enthusiast" oriented site.
Anyhoo- not saying that 18 or 19% are affected. Just trying to draw attention to the growing number of "unique individuals".

Today I detected a slight burning smell coming from my new impreza. I can't quite tell whats causing it, or if its burnt oil, clutch or plastic. Its not overwhelming or anything, but I figured I would ask as the car only has a couple hundred miles on it and I've never passed the needle over 4k rpm. I did do a couple of acceleration tests from 0 starting at about 3 to 3.5k rpm but that was very brief and mostly just to see how it did. Does anyone have any feedback regarding this?

Or, if your car has the manual tranny, it could be your clutch. Mine made a smell when it was new and I had to slip the clutch to make a difficult maneuver in reverse. But I haven't smelled that smell in months, so either the clutch is something that "breaks in", or I'm just getting better technique with this car's clutch.

Maybe I'm one of the lucky ones. Its been 4k since my first oil change and i haven't burned one drop of oil yet. Car has 9,600 on the odo right now. The oil light did go on within my first 3,000 miles of driving the car before the first oil change. No oil light since.

How much does it matter to keep the needle under 4k rpm during break in? I did a few donuts (snow) with breif stints of about 5500 or 6k rpm but other than that keep it under 4k at all times. This was all less than 30sec driving at that rpm with the donuts. Is it really significant to break in if the engine is revved fairly high early in its use for brief periods or has that not shown to have an real impact long term?

When I test drove my car, the salesgirl said "Drive it like it's yours." I asked if there was any special break-in procedure, she said no. I opened it up on some back roads, redlining several times with 6 miles on the car. After I got home and read the manual, I continued with a hard break-in, though rarely exceeding 4K. After the break-in, the engine has seen 5K+ RPM almost daily. Right now, the car has about 11K on it and burns a quart every 6690 miles, which I am 100% OK with.

You're probably fine.

I'll chime in now and later. I followed recommended on my '03 and after 178k+ it burns less than a quart over 6k miles. I am getting a '13 Legacy and plan to go easy/ recommended.
Is the OC issue related to the Impreza or Legacy engine specifically or does it cover both? Does SOA use break-in oil now that they recommend synthetic?

They come brand new with idemitsu 0w20 in the crankcase.
I think the 13' Legacy gets the new motor this year.
Check out forester.org for long term owners opinions of the fb25.

I believe they do get the new motor yes - timing chain and all which is part of what kept me in a Subaru after changing the timing belt on my Impreza myself. I guess I'll see how the consumption goes.
As for the 0w20, it is my understanding that manufacturers call for such light oil to meet the CAFE averages across the model lines. I would feel comfortable going to a 5w20 or 5w30 if consumption became an issue later in life.

One thing jrobb and myself have found is that running a heavier grade of oil doesnt slow the consumption at all. I've even tried 5w30 in the winter. florida winter (55f).

Interesting. Does Subaru do oil injection cooling on these motors?

When I picked up my car I asked to meet the service manager again. I asked him if there were any more common issues, he said no. So I point blank asked about oil consumption issues, he said he has never heard of any, but I could see it in his eyes
Ahhh well.

The only thing that will fix your oil consumption problem is a new engine. It worked for me. You just need those asses at Subaru to actually do that. Someone gave me the bright idea in these forums to drive the car really hard to burn the oil faster which meets their standards. If you have a manual tranny it's quite easy.

congrats on getting resolution! I'd say you were within your rights to drive your car "hard".

Did they find anything in your old engine that caused the oil consumption? How is the new engine working out for you so far?

My engine "break-in" style is "regular" IMO. Have made an effort to vary RPM during my drives and have not yet exceeded 4k RPMs. I do try to keep the speed and revs down when the engine/trans. are cold as long as possible before hitting the freeway. Also "down shift" the CVT manually to avoid lugging the engine when going up hills.

I just measured oil drain volume on my car's third oil change. latest consumption numbers are 1qt / 3442 miles. Filter, sample and container losses were not accounted for. I'm not concerned at this point.

You're probably fine.
Funny, I was actually told the same thing by my sales person. I asked about a break-in procedure and he told me I could just get on it all I wanted and to not worry about it. I probably should have listened to him. I ended up going with a gentle break-in and I am one of the biggest oil burners on here. I'm not saying that break-in style definitely has an affect on oil consumption, but I'm not convinced it doesn't either.

I've often theorized that a gentle break-in increases the odds of having an oil-consuming car. When I was breaking in my car, once it warmed up, I would accelerate briskly (at approximately 80% throttle) up to 4k RPM. Once I passed the 1k mile mark, I would accelerate up to red line once or twice/day (after the car was warmed up). My car does not consume significant oil (no more than 1/4 qt over 5k miles).

A friend of mine has a 2011 Forester (I know, different engine than our 2.0L), and he is of the old-school belief that cars should be broken in gently, and he changes his oil at 3k miles just because that's what he has done his entire life. His Forester consumes oil.

This is a small sample size, so I too am not saying definitively that gentle break-ins cause consumption. But I continue to wonder about it.

Looking at the results of the poll, nobody who broke it in hard has unusual oil consumption. I am wondering if breaking it in easy actually creates some tempering of the metal at the relevant locations, whereas breaking it in hard burns off those presumably exposed surfaces.

Of all the cars I've owned, this is the 4th new one. On the previous three, I broke them in easy and none burned oil. The other 7 cars I bought used and who knows how they were broken in. None of my new cars used oil and only 2 of the used ones used oil, and used less oil than this Subaru. I don't know why the Subaru would be more sensitive to break in style than any of my other cars.

Really, the only people who know the answer to this are Subaru engineers.
