2013 BRZ oil consumption
 

what is normal oil consumption for a BRZ? i hear some people talking about 7k+ interval oil changes. Is that without topping it off? for me at 3000-3500 miles the dipstick gets very low. should i just stick to 3k intervals? i set up an oil consumption test with dealer i will return in 1200 miles returning car stock. could my engine be prematurely failing? it's flash tuned with a uel header since 12k miles nothing else, it's at 27k miles now. Has always been dealer maintained have all records showing the car has never been neglected with it's maintenance. I have never over revv'd the car, i hear this is a common engine killer. Also could a compression and leakdown test with good results and still have something broken and or prematurely worn with the engine? The consumption started at around 17k miles

:slap: snap out of it, Project N64.

I'm ah feared you are trying to compare red apples to green apples. Oil consumption usually has little or nothing to do with oil change interval.

I understand is that adding a quart of oil between 7,000 mile oil chances is not unusual for this engine. My 2013 FR-S takes about 1/2 a quart between oil changes.

I suggest you just follow the oil change recommendations in the maintenance manual and add enough oil between oil changes to keep the line on the dipstick near the top hole.

Now, relax and take a nice Sunday drive … :thumbsup:

I have 0 oil consumption and I do oil changes at 7.5k .. sometimes a little higher. I think one time I unknowingly waited until 10k.

edit: im at little over 79k

I typically burn half a quart to a quart between oil changes (~5k miles). The top hole on the dipstick to the bottom hole is a quart. This is normal, modern engines burn oil on purpose.

While it would be a bit odd for an engine to suddenly behave differently, it could be that you just started noticing at 17k? Perhaps your driving changed a bit (different commute, more aggressive on throttle, etc)?

Also, it's entirely possible the dealer filled it half a quart less than maximum for one reason or another. Oil fill isn't the most precise of measurements.

I've have no oil consumption issues in my FA20 or my EJ25.

Both were broken in hard though.

If your overly concerned you can fit a "good" baffled catch can and see how much blow by you have.

If you have alot, I would then look at a compression and leak down and go from there.

Be aware that doing a comp and leak on a boxer is a royal PITA.

If your not concerned, just keep topping it up.

Thanks for the responses everyone. The car isn't driven really hard or abused. I find it very odd that plenty of people are reporting zero consumption, i understand there are plenty of factors but with me ending up low on the dipstick at 3-3500 miles i think there is something wrong (i could be wrong). I check the oil every few times i gas up. Has been confirmed to have no leaks before this consumption test. Service adviser even told me brz's aren't known to be consuming oil. Guess compression and leakdown is way to go if there's excessive oil gone.

Same brake in method in my last two Subarus, no oil consumption at all!

I did 10,000 miles on my last oil change, added no oil that entire time, and the dipstick had only lost about 1/4" of oil.

Have you checked the cam plate or anywhere to see if your car is leaking oil externally? Seems like a common sense thing to do. Clean the grime underneath the car (including around your oil pan) and next time it's on a lift, see if there's oil dribbling

Dealer did a full inspection, I made it very clear it was consuming oil they said there's nothing visable even under the car. I have looked all over the engine bay, even cam plate area because I even heard there was a tsb for it.

I'm just shy of 16k miles on a 2017 BRZ, most of that has been on back roads or on track (e.g. at high RPM/high load), and I have had no oil consumption whatsoever. I check my oil every time I fill up just in case, but it's always held to the same mark every time. I change the oil every 3k or 3 track days.

Yeah I figured you had, wondering if they actually put in the effort to really LOOK. As stated previously, unless you're billowing blue smoke, I wouldn't be terribly concerned, it happens in most engines but usually not this extensively. A quart is an awful lot. pull off your intake and PCV hoses and look for oil in there

All engines consume oil. Some more than others. Just because it uses a little oil is not a indication that it is worse shape than one that uses less. Power seats rings. If they put to much power to it early and overheated the rings you are screwed, nothing you can do but live with it. If they just did not seat good you could get them to seat a little better by running the engine hard.

If you dont get good ring and bore seal initially when breaking in the engine then you've missed the boat.

Running the engine hard will not fix the issue after the fact.
