Costs dude. They simply were trying to save money on your oil change.

Hope this works out for you.

This.
Conventional oil did not cause issue as everyone is mentioning. Your dealer is handling this the way they should, just contact them again and ask whats the situation with subaru canada.
A crank shaft bearing that is spun just a bit will knock consistently. It wont just knock one morning and be gone the next. Oil burning is likely from piston rings or something along those lines.
You just happen to have bad luck with the motor, it happens. STOP blaming it on the oil.

unless you drove hard 13k on reg oil breaking it down - the oil wouldn't have done it to your engine...if under warranty still your good still.

No no leaks under it at all. I heard a very audible knocking sound at one night of early March. Also the oil light was flickering for about several seconds when I was entering my garage, but it stayed off. The previous service was done in late October last year. I checked the oil level frequently, and it was slightly under the full mark one week before I heard the knocking sound. I took it to the dealer immediately next day, and they added some oil the sound was almost gone. I asked if they can do a leakdown test, but they spent 1 hour convincing me to do a cheaper oil consumption test instead. Just finished my oil consumption test last Monday, and an excessive oil consumption was confirmed. Then they told me they reported the issue to Subaru Canada for approval of further action. No update so far.

They added the oil to the full mark last Monday, the oil level was down to the low mark last Wednesday and I added again, and yesterday it was down to the low mark again. Check the oil every time in the morning when car is cold.
Let her buck then, if you've got a spun bearing the engine is gonna blow up well before your warranty is up and you'll just get a new motor

Literally sounds like they're doing their job, be patient and see what they come back with.

Then charged me the synthetic oil change price.

Never doing business with Peace Arch Toyota ever again.


OP, for future oil changes go to a reputable Subaru specialist! (HBL has great reviews)
How would you even know if its conventional instead of synthetic

The dealer is dealing with it, just be patient and see what they come back with before coming on here and starting a shit storm on either yourself or the dealer.

For now your car drives and runs perfectly fine. So you heard a minor knocking like 4 months ago. Big deal, you have warranty until next year. Drive the piss out of 'er until it shits the bed like every other EJ around your MY.

Op from what i remember with my 02 wrx, is that when checking the oil, the car should be warm, meaning either coming from a drive or letting it run until normal operating temperature and then waiting 5 mins for it to cool down a bit and then check the oil. I was told to not check the oil first thing in the morning when the car is cold. If this is true, then you may have overfilled your engine.

I could be wrong on this, or i could be right but only for the older subarus. Can anyone else chime in?

If it's the dealership I'm thinking of I'd be more offended by the practice of putting pinstriping on new cars and then charging extra as if a desired service was performed.

Update:
Cracked piston on #2 cylinder and also rings where stuck

Short blocked replaced under third-party extended warranty.

You probably shouldn't have hid your question in the first post.

"Never use synthetic engine oil during this process, use a straight weight, non-synthetic, non-detergent engine oil. You want friction at this point; use an SAE30 oil, non-synthetic, no detergents, etc."

Case closed. Sucks but they did their job.

I just changed back to the conventional break in oil after 150km. Hopefully the rings can still be seated after that.

Looks like I was right about it being a piston ring issue.

Stock tunes are notorious for being horrid on the STi's since MY2007. I bought my 06STi with 7000km on it and went Cobb Stg2. By 50k it had a slightly larger turbo from stock with the proper supporting mods. Up until I sold it with 125k it never burned a drop of oil or had any sort of engine problems. This is with tones of mountain highway driving and countless autox events. These engines will last, just not on the stock tune and I don't think oil type had much to do with your cracked ringland.
