OK, good to know. My friend definitely did a gentle break-in with his Forester, and I can't help but wonder if he loved his car to death.

Break-in, imo, is just a cop-out. These things come filled with synthetic. They should be broken in by the time synthetic oil ios in the crankcase, really.
But- if break in "the subaru way" is wrong, then lots of folks will be burning oil by that logic. What about the poor souls leasing these things?
And to the folks who do the "run it hard" break in, if it ends up an oil burner that black box recorder can be used to prove you didn't follow their break-in. Gotta "do your part" lol.
I doubt anyone who has consumption and did a hard break in is gonna put that on the survey.
Black box doesn't record everything, just the last few events. It was described in the service manual

Well, I know how the first 230 miles of my car were: All I-95. It was picked up at a dealship in Charleston, SC. I only know a woman drove it and I waited almost 5 hour for her to arrive, so I guess she wasn't driving too fast. By then, the break-in period is really over. It doesn't take long to break-in these modern engines today. The internals are much improved compared to waaay back in the day. However, we still have our lemons though.

How do you know that an engine is broken in during the first 230 miles, when the owner's manual says 1000 miles?

Okay, maybe not that soon but speaking for myself, my car was driven at a constant speed when manaul read you shouldn't. So my break in wasn't ideal but (knock on wood) my gas mileage is fine and haven't had any noticable oil lost after 8,600 miles. The rest of the way to 1,000 mi was normal driving, nothing above 4k rpm like the book says.

Wonder if ours cam from the same dealership. Got mine from NC and was driven to me first 236 were not by me.

I only remember 236 because my trade in vehicle had 236k on it and the people at the dealership found that very odd.

To be exact, mines had 237 miles on it but they did a swap with the dealer in Charleston from what I understand. The dealer in Fayetteville only had two back in February. A Sport Premium Sky Blue Metallic with Ice Silver and Sport Limited Ice Silver but I wanted a black Sport Limited so the search began.

it might have been Charleston SC where mine came from. It was also a swap considering my dealership had 0 imprezas and no one in a 100 mile radius had 5 speeds.

at 4700ish miles, low oil level lit again. last time was 3300ish, and 1700ish before that. at almost 5k, I really don't think it should be burning oil anymore...

What was your break-in process during the first 1k miles? How did you drive the car?

I didn't "baby" mine during the first 1k miles, but I did wind the RPMs up to 4k, at 75% throttle, once the engine warmed up. I just did my first oil change last weekend, at 1700 miles. I didn't see any oil consumption during that first 1700 miles.

I replaced the factory fill with Amsoil OE 0W20, a Subaru filter, and a Fumoto valve.

"Easy" - other than during acceleration, engine is kept under 3k RPM.

Did you wind the engine up during acceleration, say to 4k, and get there fairly briskly?

i did occasionally. i also did 2 quick accelerations up to 70mph or so pretty early on (up to 6k rpm) other than those 2 instances, it was kept under 4k.

2300 miles now, no issues so far, 1100 miles on this change and doesn't look like any change in level from when I changed the oil.

Seldom to 4k, probably 3.5k. (I up/down shift based on engine rev noise.)

I continue to theorize that not stretching the engine's legs a bit during the break-in phase might be a factor in these oil consumption issues.

More likely a design flaw on part of Subaru engineers too keen to eke-out the last possible MPG out of their engine. This only materializes in some fraction of their vehicles with same engine.

And what do you think causes that variability? Manufacturing processes are pretty consistent and stable these days. Why would some engines consume oil and others not do so, if all of the engines are made the same?

While the flaw is in the design of the engine, giving it propensity to get this condition, actual minor differences in fabrication and otherwise acceptable driving style may produce or not produce an actual problem.

Its impossible to have mass produce engine the same. Trust me. When i order rod bearings for my engine they come in 3 different dot colors RED BLUE and Yellow, Each providing a different clearance. If you match 2 blues you will get a spun bearing. As well as things are produced they work with tolerances.

A robust design accounts for looseness in tolerances, and works correctly even with those loose tolerances. Any design that assumes all tolerances are extremely tight, and fails without those tight tolerances, is not a robust design.

Are we saying that Subaru, a company with reliability ratings on par with Toyota and Honda, does not make a robustly designed engine? Really?

5200 miles here and no oil consumption problems. Did the recommended Subaru 3k break in. Don't expect any oil consumptions issues (knock on wood).

Let's say that except for negligent driving, any other style should produce proper engine break-in, with little effort from the customer (think: grandma).
If Subaru would stand behind their product to an acceptable level, of say < 1/2 quart in oil-change period and fix anything that is more, under warranty, I would not have a problem with that. However, this is not the case.
I don't believe Subaru is up to par with Honda nor Toyota. BTW, Honda was using 5W-20 oil in their previous gen Accords AFAIK, perhaps even before (oil choice alone is not the problem).
