Strange, my 2015 Forester 2.5i 6MT has seemingly stopped consuming oil by 22k miles. Had issues early on, kept using the 0w20 syn, just sorta stopped doing it I guess. Just finished a 700+mi roadtrip over new years and no issues, checked oil before during and after.

GF's 2015 XV 5MT also has stopped consuming, seemingly. No noticeable consumption since early on as well, she drives it 5 days a week, 70mi commute, its been full winter here, snow dumps, temps down to negatives a lot lately and doing fine.

Weird, but I'll take it.

Subaru settles oil consumption lawsuit:

http://www.torquenews.com/1084/subar...mption-lawsuit

"Subaru has agreed to extend its 5 year, 60,000-mile warranty in respect to the alleged defect to an 8 year, 100,000-mile warranty. SOA will also reimburse certain expenses for vehicle repairs, rental cars, towing and the purchase of up to six quarts of oil per vehicle with appropriate proof."

Default Older Subarus with excesive oil consumption

Where's the love?

I have a 2010 Forester (87K miles) and a 2007 Impreza (122K miles). Both have been well cared for and have no visible leaks and both have PCV valves replaced. Use synthetic 5W-30 on both and change oil every 5000 miles with new filter. Driving does involve short trips 7 miles (10 minutes) each way.

Impreza burns up to 4.0 quarts over 3000 miles, Forester burns 1.5 quartz over 3000 miles. Really, what gives? I have never owned a car that burns that much oil. In addition to oil consumption, the Impreza has had: New alternator (70K), Real wheel bearing (90K), new exhaust (95K), the list goes on and on.

Does this sound normal? Thank goodness I can do most of the work myself.

Sounds like you got subaru's special 2 stroke motors

In all seriousness, no, this does not sound normal. Are you the original owner of both cars?

4 qts over 3k miles is very excessive. I'm guessing head gasket, oil rings, oil pump seal, or valve cover gaskets. Something is wrong mechanically...what does your exhaust pipe look like? If its covered in blue/black soot, then you've got an internal problem. If not, I'd suspect you have a leak.

My 2002 Impreza (EJ25) had the head gasket issue and was leaking I think a 1 qt between 3k mile changes.

Probably need to start a new thread on that matter to be honest. Doesn't sound related to the newer motors oil consumption issue.

Not really that weird - it's normal for engines to consume some oil during break-in, although yours seems longer than normal.

Is it possible that your commute changed, or you started using an engine block heater? Cold engines, short trips, stop & go, etc, all affect consumption rate.

I think this is funny because I am currently dealing with Honda on excessive oil use on my wife's Pilot. According to Honda, anything under 1 quart per 1,000 miles is normal. I am having an "oil consumption test" run now to demonstrate to them that I am burning more than that. Honda has 10,000 mile oil change intervals, so I pretty much have to add 10 quarts of oil in between oil changes just to keep it topped off. If it weren't for the filter, I wouldn't need to change the oil at all due to the constant burning and refilling.

No changes, must be broke in by now I guess. It really drank its first crankcase or two though.

The word for this lawsuit they try to rip me off by putting some piston rings in my car I don't believe so who is willing to do jack crap unless you make them
It's standard operating procedure for ambulance chasing lawyers to sue every brand over every model for oil consumption.

So don't put any stock in any lawsuit because there is nothing wrong with these cars, the lawsuit will never be won, Subaru will never pay a dime, and even if they did - it's the lawyers who'll be paid, not you.
They pay for you oil when you do the consumption test. they pay for engine block, maintenance, loaner vehicle and the coffee you get when you show up. BTW why are we rolling over and letting them get the best of us. Have we lost the ability to stand up for ourselves. The facts are if your Suby burns more than 1/8 a quart of oil within 1200 miles your eligible to get a short block replaced. What are the effects on other parts of the engine components on a vehicle burning a quart or more of oil within 1500 to 3000 miles? When you look at the tail pipe and see the black smoot on your bumper does it make you wonder what its doing to the atmosphere or the air you breathe? Does the catalytic converters become saturated and cause more damage? Does the intake manifold take any damage from the burnt oil? Does the muffler become damaged in anyway?

I have 22800 miles on my '13 5MT Sport Premium Impreza. I have gone about 1700 miles since my last oil change and the oil has dropped about 1/4 to 1/3 of the way from the "full" mark to the "add" mark on the dipstick. The dealer slightly overfilled at the last change, as well. So it appears as though I am getting close to the unacceptable consumption rate. My question is this: has anyone had an engine replaced within the past 3-6 months? Was the oil issue cured? Did things go smoothly after the replacement? I question whether an engine installed by a dealership service center could ever come close to the quality of the factory. Any insight would be helpful.

I had the short block replaced in my 2012 Impreza CVT in January 2015, at 42200 miles, and the engine is now at 54100 miles. I was also concerned about the quality of the work, but have had zero problems. The oil consumption (by my own measurements, not the dealers) was 2678 miles per quart before the short block replacement, and 11600 miles per quart afterwards.

The quality of the work will depend entirely on the technician. I would choose the dealership carefully. Carlsen Subaru in Redwood City, CA, did the work on my car.
I broke in the short block with some full and part throttle acceleration. My only concession is that I am now using Subaru (Idemitsu) 0W-20 instead of Mobil 1 AFE 0W-20. Apparently there are different wear additives. I hope that this time, the oil control rings hold up...

This is why my forester has a factory 7 quart oil sump on a motor that only requires 4 quarts. Because of people like you that don't check and top off their oil.

You should absolutely expect to have to top off the oil on a brand new car between oil changes. Internal combustion engines burn oil, period.

Up to a quart every 3000 miles is the acceptable legal limit for new cars in the US, iirc.
What a joke a car engine that burns more than a 1/8 of oil between oil changes is a lawnmower motor. Why buy a car that you have to keep checking the oil every 1000 miles. Lets get realistic about it. You expect to continue to destroy the atmosphere with these vehicles? What saddens me most is you accept it on a newer low mileage vehicle as I can see it if it where a car with more than a 100k on it. Stand up for what is right or bend over and keep taking it

Default Details of my experience with Subaru

FB2.0 at 30000 miles notice oil loss about 1/4 to 1/2 quart. 31000 miles oil light comes on. to the dealership for a test. Unknown to the service guy I took pictures of oil level, mileage before and after the test. Upon return i missed the 1200 miles because of bad weather and holiday weekend. took the car in at 1400 miles. Service guy tells me that it only burned about a 1/2 quart of oil upon returning my car to me. And that it didnt qualify and I could take it up with SOA if I felt he was wrong. Before I left I told him if it only burned a 1/2 a quart then when we go out to check it it should be at the top hole on the dipstick. I smiled as we walked out to the car. He checked it and it was 1/2 from the top. I told him i read the class action lawsuit and post online about what was going on with dealerships and that I did not blame him for doing what he was told to do. Left dealership called SOA and told them how I felt and sent them my pictures. Now when i called two dealerships i was told a quart was acceptable but when I confronted them it went from a 1/2 quart on one conversation to 1/8 of a quart on the next call. SOA explained that I had to have the car in by 1200 miles in order for dealership to be paid to replace the motor. dealership told me the car had been tested once before and passed. And that it was not eligible for another test. SOA said that was not true and asked if I wanted to go to another dealership. I told them i was not mad at the first one and we can go back there for another oil test. 1160 miles later 1.1 quarts used. what do I get. a new short block with a 1 year unlimited mile or 3 year/36000 mile warranty on the block. They put all the other parts back on like the intake and surrounding motor parts. The internals are supposed to be replaced. I have been reading about replacement that have issues but I am hoping for the best. One thing to consider if the car starts burning more than a 1/4 of oil in 1k miles is it will continue to get worse. Mileage will decrease and the motor will sound different as it gets low on oil. My concern is what damage is caused by excessive oil burn to other parts of the motor if any.

I have a 2012 impreza i bought used with 30k on it. When I first changed the oil I thought it was burning oil because when i changed it I only put 5 qts in. I would check it a few weeks after I changed it and it would be down a qt. But now I realize it takes 6 qts, So I just buy some kind of addative like slick 50 or lucas oil and throw a qt in when i change it. Now I have 70k on it and it uses no oil between changes. I have done nothing to the engine. I love it. Although sometimes it starts hard. But It always starts and runs fine.

I wish something as cheap and easy as an oil additive would be a fix. Are you worried about masking an underlying problem?

Nope Not worried about a problem. I just buy a 5 qt container. And the additive is not that much more then an extra qt. Also I figure it cant hurt.

At this point I will just monitor the situation and take it to the dealer when time. The oil seems to burns progressively faster with mileage.

I've taken my XV to the dealer and they said it was within spec because of the viscosity of the oil to consume about an eighth of a quart per 1,000 miles. I am taking my car to a local shop to try Motul to see if that will help as it is supposed to help with consumption issues.

Please keep us posted. I'd be thrilled if another oil was the solution.

Yeah, I was adding 2 to 3 quarts of M1 0W30 to some M1 AFE 0W20. Basically going with an "heavier weight" oil.
But, IMO, if you still can, get your engine replaced under warranty. The difference between the new FB25 short block in my Forester and the original FB25 short block that was in there is really night and day.
More power everywhere in the rev range and, so far, I can't notice any consumption on the dipstick.
I went up in snow country (Lake Tahoe area) last month and the engine was really running well even at 6000 ft. The car never ran that well up there.
