If you've owned an older Subaru Forester, Outback, Crosstrek, or Impreza, you know some models burn oil between changes. Some owners report they check the vehicle's dipstick and add a quart of oil every 1000-2000 miles. While it's not normal, some older Subaru engines have had excessive oil consumption issues.

Consumer Reports has identified which automakers, engines, and model years that owners report adding at least a quart of oil between oil changes. Subaru's 2.0-liter engine in the Crosstrek and Impreza, the 2.5-liter engine in the Forester, and the 3.6-liter engine in the Outback are on the list.

Which Subaru models and years burn the most oil?

Owners report the 2013-2014 Subaru Forester model years have oil consumption issues. Some 2012-2013 Subaru Crosstrek and Impreza owners say its engine burns oil between changes.

The 2010-2012 Subaru Outback 3.6-liter 6-cylinder engine is also listed as an engine that burns excessive oil. Subaru discontinued the 3.6R model in the Outback and Legacy for the 2020 model year and introduced the all-new 2.4-liter turbocharged Boxer engine. There have been no problems with the new engine.

Do some Subaru vehicles have an oil consumption problem?

Torque News has documented Subaru's oil consumption problem in certain engines. The vehicles affected most seem to be 2011-2014 Forester (2.5-liter engine), 2013 Legacy (2.5-liter engine) 2013 Outback (2.5-liter engine) 2012-2013 Impreza (2.0-liter engine) and 2013 XV Crosstrek (2.0-liter engine).

Why do some older Subaru models burn oil?

The CR report says oil consumption issues surfaced after federal fuel-economy standards became more demanding. The mandates forced automakers to make trade-offs in engine design that would increase fuel efficiency but, in some cases, had an adverse effect on durability.

Using transmissions that keep the engine in the optimal higher RPM range is also a contributing factor. Subaru uses a Continuously Variable Automatic Transmission (CVT) that steps up engine RPMs and helps maximize fuel efficiency.

In the wake of an oil consumption class-action lawsuit, documented by Torque News, Subaru extended the factory warranty on some models (previously five years or 60,000 miles) to eight years or 100,000 miles, whichever comes first. Read the full class-action lawsuit report here.

Has Subaru corrected the oil consumption issue?

According to Consumer Reports, there were significant improvements in the three Subaru engines listed above after the 2014 model year. Owners reported they were not adding oil between regular service appointments in 2015 and newer models.

Reports say the Japanese automaker redesigned the 2.5-liter engine in the Forester and Outback in 2012 and has fixed the problem. Some 2012 Subaru Forester models could still have the older engine design before the automaker changed over to the next-generation 2.5-liter Boxer engine.

In Consumer Reports annual surveys, owners now report zero problems in 2019 and newer Subaru models. New car shoppers will find the 2021 Subaru Forester and Outback 2.5-liter engine and Crosstrek and Impreza 2.0-liter engines are fuel-efficient and reliable.

I have a 2015 Forester 2.5i that often needs one extra quart when the warning light comes on between oil changes.
Same problem. 2015 model that needs oil every 2k miles. I keep two courts in the car at all times.
This is the best built vehicle in the US.
Pretty much all Subaru engines leak oil as well as probably burn It. Would have to disagree with the comment about it CVT stepping up the revs. Pretty much the opposite. The revs are maintained at around 2000 unless accelerating hard or climbing a steep grade or probably towing.
Our 2010 Outback with the 2.5i engine with 160k miles has never leaked or burned oil. My buddies 2020 Outback with 2.5i burns around 0.75 quarts per 5k miles.
My 2015 Forester went through a quart of oil in 700 miles going through the west deserts of California, Nevada, Utah during the sever heat wave in June-July 2021. Has typically gone through a quarter every 3,600 miles. I have found keeping the RPMs down in 2-3K range helped.
My 2016 Forester 2.5 liter burns nearly 2 gallons beteeen oil changes. Ridiculous.
My 2013 Outback use to burn at least a quart of oil between most oil changes. Subaru replaced my engine at 100k miles under the class action suit. They claimed the excessive oil consumption was due to faulty o-rings which was allowing oil passed.
Interesting. Did you get an oil consumption test from Subaru? Was the excessive oil burn apparent after 1200 miles? Curious because my 2013 Legacy does even worse but Subarau says oil consumption tests show no problem.
My wife and I have daily driven a 2013 Crosstrek Limited since new. It currently sits in the driveway with a little more than 80k miles. It does not, nor has it ever used a drop of oil. I am about to perform the next oil and filter change, something I do myself every 7k miles. I guess we should feel a little lucky. I also purchased a used 2005 LGT wagon six years ago, with 60k miles on the odometer. The seller was up front about the 2.5 liter, turbo engine using one quart of oil every 1000 miles since delivery as new in 2005. The dealer claimed this was normal. The seller was accurate on that oil consumption rate. I always kept an extra quart of oil in the rear side storage bin. Oil and filter changes were performed every 3k miles or less. The original owner claimed oil/filter changes were preformed every 2k miles. Over my six years of ownership, the LGT's oil consumption rate remained constant. If one loves their Subaru, they surely would not wait for the low oil warning light to come on before adding oil. I cringe to think someone would do that. It's not a bad thing to be in tune with one's vehicle, checking oil regularly. It helps avoid other surprises like low washer fluid, low brake fluid, low power steering fluid, low coolant level. They are all right there for the checking.
I bought my 2013 Legacy 2.5i Certified PreOwned from a Subaru dealer, with 26K miles on it. From the start it burned a quart of oil as soon as every 1200 miles or at best every 2000 miles. The dealer never told me, even when I complained about it, that my car was covered by the court settlement facilitating a free oil consumption test, and a possible repair, Subaru says my car doesn't burn enough to make them liable for repairs (like replacing the short block, or maybe the piston rings) so Subaru of America and the dealer has done the absolute least that they have to. I've had total clunkers that don't burn oil like this.
2015 Forester 2.5i w/manual trans. Has always burned 1 quart per 500 miles at highway speeds, though a bit less when driven around town. Always keep two quarts in the car so I have some to add when the low oil light comes on. Ridiculous! Never buying a Subaru again.
My 2017 Forrester constantly needs extra oil between service intervals. I've taken it back to the dealership to no avail. It still needs an extra quart after about 3k miles
My 2000 outback sport's engine ran completely out of oil at about 260,000 miles. I was totally unaware that it was using oil. Got a newer motor put in with 60,000 miles . The car had about 350,000 miles on it when a deer collision totaled it and I only had liability insurance on it, so sold it for scrap. Lesson, always check your oil on a higher mileage car!
My 2019 Forester uses NO oil between services...I have been watching closely. I’m retired with over 50 years in the automotive industry so you could say I did my homework before I bought the car as I knew of prior oil consumption issues in the older engines. It’s the best vehicle I’ve ever had.
2013 Crosstrek 170000 miles. Adding a quart just under 2000 miles. If I forget to check the oil light will come on by 2000 miles.
Why do subaru forester 2007 to 2010 have the problems with the steering rack
