Amount of oil added between changes

have 40k on my 2015 2.5 premium, also have a 2015 outback 2.5i,21k on it- not a drop used in either, a huge turnaround from the 2012 forester I traded in; I would add 1.5-2 quarts between changes, half quart at a time

lscmark. So you go 6k between changes and the oil level is at the full mark ?

 

Was it always this way for all the changes? or did it get better with more mileage ?

 

I'm at 23k and have noticed about 1/2 quart low.

 

Thanks,

Just had my 6 months service (5500 miles) (second oil change) after a 1650 mile road trip in my 3.6R liberty/legacy. So far I've never had to add oil in between oil changes.

 

(mainly highway driving)

15k miles, 3rd oil change, Mobil 1 full synthetic, perfect oil level in my 3.6r

It would be better if the poll included a "none" category.

I change my oil at 6k and have never seen the dipstick below full. The oil is also very clean. I suspect that not needing to add oil is the norm.

 

I've never like to see oil come out of an engine looking new. It means its

not working to keep deposits out of the engine. Even normal combustion by

products should cause the oil to darken somewhat.

Almost at 40k. Never had to add oil yet. I always check before I get the oil changed and it's usually just under full to half quart low. I don't even have spare oil bought for this car yet.

This true to an extent but it doesn't concern me one bit. Today's modern engines are so much more efficient than engines of even five years ago that the left over deposits are getting so miniscule that they hardly affect the appearance of the oil at all.

My engine oil doesn't look out of the bottle new but it's not far off. And I never have to add any between changes.

Deleted my fifth gen post. Interesting thread to read though, kudos on the thread! Edited July 31, 2017 by Izzypal
I didn't realise it was a sixth gen thread (SMH)

Did my oil change again in May.

Odometer at 19,000 miles, 4000 miles since prior oil change. No oil added between changes.

Dipstick was showing minimal loss -- less than half a quart.

2017 Legacy Limited 2.5

 

We are approaching 9k on the odometer at the moment. So far, 0 oil consumption. Knocking on wood of course that it never starts.

Mine started burning oil at between 15-20K miles. Was zero up until then.

Both my Subies ( spell checking ) the H-4, H-6 been just fine.

37,000 Does not burn any, so far.

My Legacy currently sits at 78k. I've gone from using it as my company car to having it be my wife's around town car.

 

As my company car it frequently saw 1000 miles a week and 90% usually at speeds between 70-80 mph. I believe around town speaks for itself.

 

When cruising those at higher speeds for long distances I was adding at least a 1/2 quart between every oil change. Now that it's around town mostly I am not adding any oil.

 

Just one person's observations, your mileage may vary...

Update from my situation. I wass told that i needed 2 oil light in between 2 oil change to have my warranty case ''registered''. I went from doing 8000 km to 6000 in the last 30 000, but it light up yesterday for the second time in-between 2. This means that the car took about 2.5 liters in 10 000km. So at 40 000km as of today, I'm waiting for a new short block under warranty...

Thanks for the update. It's hard to know what's causing those breakdowns in some cars but not in others. Let us know what they discover.

 

My last change in Oct at about 26,000 mi required no oil added.

I'm at 48K, have to add zero between changes performed at 6K.

 

Thought I'd toss that in here.

No added oil between changes on my 2.5i.

2nd oil change completed few weeks back ... full synthetic both times; 1st time had the additive added on a coupon for 0 up charge.

Include your cylinders(if not in your signature/profile): 4cyl 2.5i

Odometer: 12,100

miles driven between: nearly 6,000

Quarts added: 0

driving style (easy, moderate, aggressive): Easy / mixed 90% ; spirited/ heavy acceleration 10% - usually merging, ramps, turns, passing the semi's that cant stay in own lane due to shitty road surface on interstates in Illinois

Full engine operating temp (sometimes, usually, almost always): Almost Always

Still averaging 6000 miles every three to four months and no added oil in between changes. I’m at 57k now. I always check it before I go in just to see where it’s at and how dirty.

Odometer: 25,647

Miles driven between: ~5,500

Quarts added: 1 quart

driving style (easy, moderate, aggressive): Moderate

Full engine operating temp (sometimes, usually, almost always): Sometimes

Lifetime mpg or L/100 km: 20.4 MPG

 

So I've had my 3.6R for over a year and I've taken it to see the dealership over 12 times due to low oil and scheduled maintenance. After raising my concern to Subaru of America (SOA), they suggested that I take my vehicle to the retailer and start a oil consumption test.

 

During a Oil Consumption test: A new oil change is completed to the vehicle and the customer is to drive the vehicle 1,200 miles. Then return to the retailer to measure the oil burned. If the vehicle has burned over 10.3 oz per 1,200 miles, the vehicle has FAILED the consumption test.

 

My Results?

FAILED.

 

During the test the Check Engine Light flickered once and the oil light also turned on a few times. My drive is mainly in the city, with a few trips on the highway on a weekly basis. Not much of a racer, but I love an occasional WOT on an on-ramp.

 

I'm working with SOA and I'll keep you updated on what they say.

Can't speak for anyone else's experience, but I had my engine block replace under warranty.

 

That being said, I actually had to send a cease and desist letter to Subaru Canada threatening to sue them if they did not replace the block.

 

Then again, my oil consumption was much less critical than your case seems.
