Default New 2019 STI Break Procedure?

Miles 500 to 1000 I varied revs a lot, engine braked a lot, made sure to cool down in between pulls--just like in the first 500 miles, but raised my 4500 RPM limit to 6500.



I'm only at 2300 miles now and haven't gotten a compression/leakdown test or anything so it's certainly too early to say whether my break-in worked.



I'll probably catch some flak for this but my manual says I don't need to change oil at 1000. I check it every time I fill the gas tank; no glitter and it's a lovely amber color so I suppose I'll change it at 3k or so. I'll make sure to remind everyone of my break-in procedure in my "stupid ej25 engine blew up" post.


This is how I broke in my 2014 WRX. I believe in hard break ins. Iíve had plenty of new cars and have always done it like this. Maintenance is the key.

Have fun with it and donít worry
Mark
Edit, my car doesnít use any oil what to ever. 24000 miles so far.

It will be a good idea if you start a repair bank account. STIs engines break without any warning, specially if you start modifying it. Dealership / Subaru tend to blame the driver for any defect damage found.

If you are going to modify it, your first mod should be AOS (air oil separator). STI engines take in a lot of blow-by and causes the car to misfire / detonation. ECU doesn't report it unless it's a major misfire and by then the damage is already done.

I just broke in my 19 STI by following the recommended break in period. I am going to keep my car stock for now. Modifying is fun though as my previous 2011 STI was stage 2.

Even if you don't do a full oil change before the first scheduled one, changing only the filter (and topping the oil level off) ought to be better than doing nothing at all.

Half the oil is coming out as soon as you pull the thing anyways, might as well finish the job...

True. STI is still a bottom mount oil filter.

yeah but it's not below the pan.
I'm pretty sure it's just what's in the filter like anytime you remove a filter, although I've never actually pulled one on a car with a full pan

never the less, on the STI 90% of the work is removing the underbelly pan to access the filter so there's really no motivation to leave the oil in there after all that work

Oil and no filter change, there's motivation for that since you don't have to remove the pan.

It's not like you're always going to be changing only the filter midway through your regular oil change interval. Just partway through the first one, when you can expect engine operation has generated more debris than it will over any later span of a thousand miles. Unless it does go "boom", anyway.

Getting at the 2.5L STi engine oil filter appears to be identical to getting at the 2.5L Legacy 2.5GT's oil filter. Access really isn't all that bad, not even for an old guy like me working with ramps and a creeper.

There are a few tricks to minimizing the amount of oil that dribbles over your hand and any components located lower than the filter seat (exhaust tube?). It might even be worth doing the filter only the first time just so you won't be working with a drain pan already half full right where your arm needs to be and where a dropped oil filter would . . .

On my 2011 STI I changed my own oil and hated taking that underbelly tray off that was most of the work and it is a pain in the rearend. Oil and filter were easy. I think on my 19 STI I am just going to pay and have it done. I have a $10.00 off coupon from Subaru.

^tell me about it

I do the filter every other oil change which eases the pain.
ridiculous they didn't make an access for the filter, removing the tray sucks it

There's two ways to break your car in. Like Subaru tells you to, or every other way listed in this thread. The only one that is "right" is Subaru's recommendation. Everything else is just anecdotal.

My personal opinion of hitting the 1000 mile mark is that you're ready to go after that oil change. Burn it up.

If Subaruís recommendation is right in regards to break-in procedure why do refer to a 1,000 mile oil change when Subaru does not?

Keep in mind that 'anecdotal' includes the opinions of people who have assembled engines from piles of new-in-the-box parts and freshly machined major components. Even within this thread's small population, guaranteed.

Because of the two words in that very same sentence which are "my opinion".

I hear ya Norm. Engine builders as a group are not necessarily consistent with their recommendations. Meaning my builder said 1K miles of gentle driving, where as another says 1,500 miles with varying rpms, another says 500 miles, blah blah blah. If one is building an engine with all stock parts and tolerances, then the factory recommendations would hold. If one is building a motor perhaps with aftermarket performance parts, and different tolerances, then that's something different.

However, we're talking about a new car in this thread. From the factory.
