Subaru is pretty well known for its reliability, excellent designs, long-lasting engines, and fuel efficiency, but not all models of all times follow this up. It still may run into a few issues as there were oil consumption problems in certain engines.
Now the question comes, do Subaru engines burn oil? Then the answer for this question is quite twisted as not all Subaru engines burn oil or have engine issues. Only a few models in certain years showed issues as reported by users.
They managed to identify which model years, engines, and automaker that owners report having certain excessive oil burn and consumption issues. Read ahead, and you will come to know about the specifics like models and time period of problematic engines.
Subaru Engines Burn oil Specifics
From people owning a Subaru, it was found that the 2.0L, 2.5L, 2.4L, and 3.6L engines giving power to some Subaru vehicles built after 2011 showed some major issues of consuming more oil than usual.
However, there were many other such engine oil burning-related issues recorded in other time periods as well, and customer complaint records recorded that.
The 2013-2015 Subaru XV, the 2010-2014 Subaru Legacy 2.5-liter engine, the 2.0-litre engine in the Crosstrek and the 2.0-liter engine of Impreza owners stated that its engine burns oil between changes.
Many more complaints are registered regarding the Subaru 3.6-liter engine in the Outback 6-cylinder engine, which is also listed as an engine that burns excessive oil.
The 2003-2008 Subaru 2.5-liter engine in the Forester also presents excessive oil burning problems. However, the fourth-generation Subaru Forester of 2014-2018 is noted to be the most problematic for oil consumption.
An all-new 2.4-liter turbocharged Boxer engine was introduced after the 3.6R model in the Outback was discontinued and Legacy for the 2020 model year was introduced. There was not recorded even a single-engine oil burning problem for the new engine.
Subaru Engines Burn Oil Causes
If you want to find out what actually causes such a situation, then some key factors can cause your Subaru engines to burn oil more extensively if not looked upon.
If the seals or gaskets of your Subaru engine wear up, it will result in oil leaks, so keep checking them regularly.
Oil may flood the engine excessively and be burned up when the oil pressure is high. If you use oil of low or poor quality, it is more likely to get burned up faster than high-quality oil.
Sometimes, when the piston rings get worn out, the oil will escape and get burned inside the combustion chamber. Old engines have tiny spots of natural wear and tear, allowing the oil to leak through them.
It is easy for synthetic oils to escape and escape through much smaller holes as compared to normal oils due to their formulation.
What did Subaru do to resolve the engine burn oil problem?
Subaru, accepting the inconvenience and problems caused due to engine oil problems, has stepped forward to take steps ahead to resolve these issues. They decided to take a course of action for the affected models.
There was also a class-action lawsuit filed against Subaru by some Subaru vehicle owners for the excessive oil consumption in their vehicles. Subaru settled this lawsuit by agreeing to certain criteria as part of this settlement.
They agreed to extend the powertrain warranty of 5-year, 60K-mile to 8-year, 100K-mile on all listed models and offered a free oil consumption test to help all current Subaru owners to keep track of oil consumption.
Subaru took a great step, by goodwill and maybe an effort to save the brand’s reputation and present advice to the people for replacement of the piston rings and that will get covered under the warranty of the vehicle.

Most of the data and information that we have looked at was based on the reports and steps taken for old Subaru models in the past few years.
Basically, it was a journey of learning and machinery trials that resulted in today’s fuel-efficient and reliable engines that Subaru managed to pull off.
There were reported zero oil burn problems in 2019 and new Subaru models by the owners. According to consumer surveys, even the latest models, the 2020 Subaru Forester, Crosstrek, and Impreza models, turned out to be quite fuel-efficient.
