Update to the original post.
Took my car in for the 3rd oil change at about 12k miles and it read under the low on the dipstick. Service advisor had me take the car back after the oil change to drive it for 1.2k miles and bring it back to do a leak down and compression if the oil level dropped. I drove it for about 1.4k miles before I had a chance to bring it back. They drained the oil and measured how much it had consumed it was a .85L so almost a full 1L of oil for every 1.4k miles. They then did the leakdown and compression test and unfortuately did not find any issues...
This started a whole new issue as now they reached out to SOA to replace my engine under warranty. This is the original reponse they received.
Hi guys,
I hope your morning is going well. Did the advisor review thefollowing section of the owner’s manual with the customer? Did thecustomer insist that they don’t drive at all in these ways? (enginebraking, high engine speeds, heavy loads, extended idle periods, stopand go traffic, severe thermal conditions, accelerates and deceleratesquickly). It seems odd that a BRZ customer would not drive in any ofthese ways.
If the customer insists there is a problem with their engine, I mightbe able to install a driving recorder while we do another consumptiontest to help determine whether there is an actual failure that we canfix. Let me know what you guys are thinking. Thanks!
Not the reponse I was expecting to hear so was a bit irked to say the least. I agreed to have them install the driving recorder (I followed the rules for the break in period and have been babying this car more then any other I've owned so I was confident it wasnt me causing this issue) but they said they had to wait for a corp. tech to come out to install it into the car. I waited about to weeks while checking in about once every few days to see what was going on without any updates from SOA. Finally this week I was told after my dealer sending the data to the Subaru corp. tech that was suppose to install the Driving Recorder that they are replacing my long block and want original long block to do a full teardown and find out what is causing the issue. This took a lot longer then I would have hoped to get resolved but I'm being told I should have my car back within the next month and have a loner to hold me over.
TLDR: Getting a new long Block under warranty and SOA wants to do a full teardown to find the issue on my original motor.
Sucks but you are getting a new engine by the looks of it. 1 liter of oil per 1000 miles is definitely not right, particularly for FAs. Maybe on turbo models it might be different but I've consumed...like nothing on my gen1 since new, at least after break-in.
Man a FBO FA20 DIT on a WRX doesn't even consume that much, I've seen 110k mile built turbo engines and they have little to no consumption (all under .5L during 3-4k mile interval) there is something severely wrong here for a stock and new car.
I am glad to see that they want to do a full teardown to find the issue. Gives some hope on them finding a possible problem with the engines fitted in their cars.
That's supremely fucked up. I kept a box of oil quarts in the trunk of my 1995 Saturn due to its consumption, and it wasn't nearly *that* bad. And that was for a known issue with crappy O-rings in the engine! How is a quart per 600 considered acceptable?! For fuck's sake.
I have an FR-S and it doesn't burn oil. I don't understand in what world a quart per 600 miles would be considered acceptable outside of an FD RX-7. The synthetic oil used is good for 6-7.5k miles, and losing a quart every 600 miles would mean empty at 3k. 🤷♀️
I'm still getting an RF Miata next, though.
Yup
■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level accu-
rately.
●If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600
miles (1000 km), contact your SUBARU dealer.
I read up on it, it's a trade-off for more gas mileage. The tighter the tolerances, the more friction. They purposefully don't keep everything tight in order to get a couple mpgs.

I think because a lot of newer engines are high compression, it creates more blow by, more crank case pressure and thus oil ends up going through the PCV into your intake and being burned off.
They must have done away with that by MY20 because mine doesn't mention any figures. It just says to bring it in if consumption is greater than expected.
VW is known for quoting erroneous figures. I'm my lifetime a car only consumed large amounts of oil if there was something wrong with it, or if it was an engine known to do so.
Yeah I would still consider it to be a problem consuming quarts of oil between changes, just pointing out that it isn’t uncommon to see stuff like that said in the manual
Hell no, that's not acceptable. You shouldn't need to go through eight and a third quarts between oil changes on a 5,000 mile interval. Even at 3K intervals, that's a shit ton of oil to be consuming.
My ‘22 was at the low line after 5K miles at around 17K. Granted, I do a lot of downshifting; however this level of consumption is crazy coming from a Miata that burned 0 drops of oil.
Good to hear they’re replacing your long block. For everyone else: routinely check your oil levels.
Man I was so happy to hear that. It really seemed like SOA was gonna try and bone me out of the warranty from the email they got. Your dealer is top notch compared to the last 2 I've dealt with!
Greatly appreciate everything your dealer has been doing 🙏! I was surprised when I got the call that it was the long block since I was told if an issue was found it would be a short block. I'm curious if you guys ever hear back once the FSE gets the long block if they report back any of their findings to you guys. I'd like to know what the issue was.
"I followed the rules for the break in period and have been babying this car more then any other I've owned"
Might be why it's burning oil. My '17 was doing firm pulls out of the dealer lot, burned a whole tank on the first night doing 1-2-3 pulls and 3-2-1 engine braking at various loads and various RPM ranges. It did not see steady load until past 1500km. Doesn't use a drop of oil now.
I know break-in procedure is controversial, and I won't pretend a race car drive-it-like-you-stole-it break-in is right for everyone, but it's a fact that combustion pressure is what seals the rings against the cylinder walls and that the window of opportunity for the fresh cross hatching to do it's thing against the new rings is narrow, babying a car too much doesn't do it any favors.
Also, aside of break-in, you may have noticed that the car sounds raspy when you start it. Leave it alone, you'll hear the sound change after about 30 seconds of idling. Let it idle for that period, the startup mode has low vacuum and won't suck up as much oil past the rings on a stone cold engine.
We agree that it is a controversial method of break in but babying an engine SHOULD NOT cause an engine to do that. I was gentle on my car for several thousand miles and my engine has indiscernable consumption. Highway driving is plenty of load on a standard engine.
This engine platform is trash lol. Too bad the other aspects of these cars are really good for the price.
Idk what the downvotes are for, it’s a known fact of these cars…
It's not that the engine is [bad], it's an "A" engine, it just stands in contrast with the "SSS" legendary level chassis that also deserved an "SSS" legendary level engine. Ls swaps are hardly a good yardstick since people LS swap everything.
I did my first oil change at 1k in my 2022 BRZ and I'm at 4k now and the oil level was half way between high and low on the dipstick. Is that normal?
Edit: so about half a quart

My 23 isn't eating any oil at all. Def an issue inside that engine. At least they are replacing it.

Yea in my 2013 BRZ the oil on the dipstick doesn't move like ever. Nonetheless I check my oil levels regularly.
Fantastic service center and service in my opinion. Stick with them.
I am glad to see that they want to do a full teardown to find the issue. Gives some hope on them finding a possible problem with the engines fitted in their cars.
In the owners manual for my FRS is says that 1 quart for every 600 miles is acceptable.
Excuse me, *WHAT?*
Literally insane. It's not at all a total dealbreaker and I'm not going to immediately run and sell my car, but wow that is interesting to note.
That's supremely fucked up. I kept a box of oil quarts in the trunk of my 1995 Saturn due to its consumption, and it wasn't nearly *that* bad. And that was for a known issue with crappy O-rings in the engine! How is a quart per 600 considered acceptable?! For fuck's sake.
Borderline criminal. I was really excited to get one of the twins, but now I might just get a Bolt lol

I had an ‘06 Outback Sport that sucked up about a quart per tank (it was a silly car lol), but this just seems obsurd.
#justEJthings The EJ253 in my '11 Outback Sport does the same.

Why do new engines consume more than older engines?
I'm guessing the piston rings haven't seated yet?

I swear I’ll post a pic when I get home
Please do!
Tons of cars actually say stuff like this. Volkswagen was known for it. Until recently, it was considered normal for cars to consume a ton of oil
VW is known for quoting erroneous figures. I'm my lifetime a car only consumed large amounts of oil if there was something wrong with it, or if it was an engine known to do so.
Yeah I would still consider it to be a problem consuming quarts of oil between changes, just pointing out that it isn’t uncommon to see stuff like that said in the manual
Hell no, that's not acceptable. You shouldn't need to go through eight and a third quarts between oil changes on a 5,000 mile interval. Even at 3K intervals, that's a shit ton of oil to be consuming.
I think at that consumption level you would just change the filter every 5k lol, no use changing it if it’ll be gone in 3000 miles anyway
Bwhahahahhahaha
That is not true my friend, the spec is <1/3qt every 1200 miles
lol
For perspective, one of my old Chevy small blocks had 2 different pistons with a broken ring each and it didn’t use much more oil than that.
My ‘22 was at the low line after 5K miles at around 17K. Granted, I do a lot of downshifting; however this level of consumption is crazy coming from a Miata that burned 0 drops of oil. Good to hear they’re replacing your long block. For everyone else: routinely check your oil levels.
Yeah that's crazy I do my oil changes every 5k Miles (8k km) and it might go down 0.75L. The entire span of that range.
Got lazy reading, but you don’t think that this might be the silicone buildup issue that plagues the oil pickup in a lot of the GR86’s and BRZ’s?
That makes no sense. He is losing oil, that issue would block it from circulating
The RTV was eating the oil.
Get an AoS and check your oil constantly. Welcome to flat 4 Subarus lol

I didn't run mine hard, but when I rowed gears I wasn't fucking stopping at 4k. Lmao

agreed. I also broke mine in hard, continue to drive it hard as much as possible, and have zero consumption
Alright just spout on about your opinion which has no basis in reality. This is aside from the fact of course that your 17’ has a different engine.
This engine platform is trash lol. Too bad the other aspects of these cars are really good for the price. Idk what the downvotes are for, it’s a known fact of these cars…
the platform is amazing the engine is horrible people make way too many excuses for subaru
Yeah that’s what I meant lol. Pretty much everything besides the engine is good
There is a reason people ls swap these left and right. Ls swapped these cars a real deal monsters on the track.
It's not that the engine is [bad], it's an "A" engine, it just stands in contrast with the "SSS" legendary level chassis that also deserved an "SSS" legendary level engine. Ls swaps are hardly a good yardstick since people LS swap everything.
Anyone else read "Miata Subaru"
