How many miles are on your 2010? And, are you saying that you used 1/2 litre or quart? In those two weeks how many miles did you drive and where, under what conditions? . Desert heat , 110 degrees, mountains?

122080 miles driven in heat conditions

1/2 litre

The mark oil plays a role on to gobble up oil

If your issue is excessive oil consumption....Take your vehicle to a Toyota Dealer and ask if your vehicle is covered by the extended warranty on this engine.


Hmm, 122,080, that's an average of 24,000 miles per year. All highway driving? And, you mentioned high heat, what is that 100 degrees or close to that number?. All of these factors, higher rpms, high speed and heat contribute to more engine wear. And, no matter what anyone tells you, all cars have the capacity under certain conditions to burn some oil. So, you used one half quart or half litre, what are you complaining about? Look, you drive a thousand miles every two weeks. One last thing, your car is out of warranty. The person who made this comment is dreaming.

For those of you who are interested. Certain Toyota engines have an defect. These are Toyota's 2AZ-FE 4 cylinder engines. If they burn more than 1 quart of oil in 1,000-1,300 miles Toyota will repair this defect up to 10 years or 150,000 miles under a Warrantee Enhancement Program. Check it out. Google "Toyota Excessive Oil Consumption" BTW...it is still not clear to this reader. How much oil is this vehicle consuming in about....1000 miles?


Lastchancegarage - thank you, I didn't know about the 10 years or 150,000 miles. There's a lot of people with Subaru cars that would probably give their eyeteeth to have this kind of coverage on some of the later model FB series engines. I'm going to check out the Toyota engine you're talking about. We have a 2009 Toyota Prius and to my knowledge, it doesn't burn any oil. We just take it in every 5,000 miles for regular service intervals. Yes, you're right, the original poster here needs to be clearer on how much oil they're actually using.

Markw1952. You are welcome. Seems those low tension piston rings many manufactures have gone to are the root cause of this problem. Hopefully, Subaru will "step up to the plate" and take heed to the Class Action Lawsuit" they now face concerning this issue. My guess is the next battle will be with the damage to oxygen sensors and catalytic converters resulting from this issue. It will be interesting to see how Toyota handles that.


Lastchancegarage - I don't know why manufacturers who have a winning product, like the phase 2, EJ 25 series Subaru engines dating back to 1989 and a refresh in the 2000s with the phase 2 series has to re- engineer a perfectly good motor and create problems with the new version? Do you have any idea? My 2010 Subaru Outback Limited has the EJ 25 series 2 motor and this engine was used throughout the 2012 model year on the Outback until they changed it in 2013 and used the same engine as the Forrester which started using the newer engine in 2011. They made some substantial design changes including a double overhead cam, timing chain and re-position of the valves. I guess they also changed the piston rings and the called for a lighter oil viscosity, synthetic 0-20 from the previous 5-30. The whole thing only netted 3 to 5 horsepower in the newer 2013 to 2015 cars. While it doesn't apparently affect all cars, some are burning more oil and people affected are rightly upset and have reason to be. Subaru has offered the affected people to do an oil consumption test on their cars and in some cases replacing their engines. I have 72,000 miles on my car and have no excessively high oil consumption. Only time I used even a little oil was pulling my teardrop trailer into the Sequoia Kings Canyon mountain area. It's a steep climb and the 2.5 Four with the CVT transmission did an amazing job. No problem with that whatsoever. The Subaru engine is a pretty gutsy power plant and very efficient. Of course my teardrop trailer only weighs 1,000 pounds, but we had some gear in the car as well. The flat Four is plenty enough and can tow 2,700 pounds. Here's a picture of my rig.

Changes to these reliable and efficient engine are made for three reasons. (1) $$$$$$. If it can be made cheaper they will make more money when they sell the vehicle. (2) Compliance with Federal and California Emission Control Standards. These standards change over time. (3) Corporate Average Fuel Economy Standards. A major concern of all who import or manufacture cars to/in America. If they can tweak 1/2 mpg out of these engines....they will do it. Designing piston rings with less drag on the cylinder walls reduces piston to cylinder wall friction. Thus, it takes less fuel to achieve a certain torque/horsepower level. What concerns me most about this industry is the long standing position of most automobile manufactures. They KNOW a defect exists. They continue to build and sell these defective vehicles. The attitude is..."Let's wait for the customers to complain...and/or..."We'll fix it at the Dealership level". Classic example of this strategy......GM Ignition Switches.


lastchancegarage - I know they're trying to comply with CAFE standards and tweak cars to get better fuel economy, they've made changes like electric power steering and other things, which are good, but, playing around with the piston rings and seals to reduce friction and changing oil requirements making engines more susceptible to burning oil is not a good idea. So, you'd agree that the previous EJ 25 series engines from 1989 to 2012 on the Subaru Outback and Legacy were more substantially better? I'm happy with the car and my fuel economy considering what the size of the vehicle is and what it can do.

Frankly...I am not that familiar with the Subaru brand. I have heard they are having a problem which is serious enough to trigger a Class Action Law Suite. When ever you decide to change oil viscosity and especially to a synthetic.....you have to change the design of pistons and rings.. Then you must face a substantial validation process to confirm the reliability of your mods. That cost $$$$$ and time. The idea of changing your oil from crude to fully synthetic is a risky one. One would have to closely monitor engine oil consumption....O2 sensor and CAT efficiency....and oil leak issues. So...in my opinion, Stick with and continue to maintain your vehicles with what works. Stay away from mods like changing engine oils....air intake mods...performance computer updates. These usually creates problems you never contemplated.


Lastchancegarage - after consulting with Subaru and my independent mechanic, who's been working on my cars for 15 years, I decided to switch to synthetic oil for my 2010. The difference between the 2010 and the newer engines is not the oil but the rings and piston clearances. Subaru says that synthetic is optional, but starting even in 2011 it's required. Synthetic oil just lubricates more easily and doesn't break down as easily. And, my mechanic says it's not a problem to use either oil , but, synthetic is preferred oil of choice. With respect to the oil burning lawsuit, it's not over, people should not ignore that fact! And, Subaru has made some progress replacing some engines for their clients who participated in the oil consumption test and demonstrate that they have a real problem. Unfortunately, a lot of people don't take the time and follow procedures to get this done. It's my general understanding and this is just based upon anecdotal information from articles I've read online indicating most of the oil burning issues are Subaru Forester models with the manual transmissions. If people only want to complain about it and not follow through with the oil consumption test procedure then it's their problem.

My understanding of Synthetic vs. crude is synthetic is superior for engines operating at higher temps. Higher normal operating temps can burn fuel more efficiently. So...your fuel economy improves. Selecting the correct viscosity oil becomes paramount based on ambient and its effect on an engines NOT. Some synthetics are actually a blend of crude and synthetic oil. It always has and continues to be a controversial issue. It is interesting to note....when I first entered the Auto Service and Repair Industry back in 1954.....oil changes were recommended every 1000 miles. Piston to cylinder wall clearances were .003 inch. Today..... For a Auto Manuf. to suggest in the owner's manual that Using a quart of oil every 1200 miles is normal.....is ridiculous Modern engines have piston to cylinder wall clearances of .0005 or less . Most engine rebuilders now SELECT FIT pistons to cylinders. When you purchase a new car....are you made aware of the vehicles FUEL Economy? Are you made aware of the OIL ECONOMY? Would you buy a new car that uses a qt. of oil every 12000 miles? My advise to all remains....use what works. Interest exchange of ideas....thanks.....Tony C


Tony, thank you, I appreciate the opportunity to exchange ideas as well. First, let me start by saying, people purchase vehicles based upon the past successes, so, if a model like the Honda Accord in the 90s. I know, my last car was a 1995 Honda Accord EX with the VTEC engine, way ahead of its time. Great car, kept it for 19 years, only sold it for the Subaru Outback because I needed a more powerful car with better ground clearance to tow my teardrop trailer. My advice and strategy when purchasing a car to look for a nameplate that's been around for years and people highly recommend the car. The Subaru Outback is one of those cars until very recently in 2013 when this oil burning issue surfaced. It's pathetic to think that you have to be some kind of mind reader to know when and where a change might occur and turn an otherwise good car into a dog. It even happened to the Honda Accord in the 2000s, with the transmissions going bad when they started farming out the manufacturing process to an outside company rather than build their own product . It was a disaster. Later, they went back to building their transmission again, but, the 2008 Honda Accord was the worst. Starting again in 2010, they got better, but, and this is a big one, all of those people who paid good money and got burned remember and that's bad. SO, when I hear people and their current circumstances, I have to say, I feel damn lucky that I chose the 2010 Subaru Outback Limited with the CVT transmission. We also looked at the 2013 model and I'm glad I skipped it. Also glad I chose the Four and CVT, mainly because, the H6 didn't offer it and only until 2015 did they adopt the CVT transmission for all Outbacks. And, when you said that you find it inconceivable that a car company can say burning one quart of oil every 1,200 miles, I agree that it sounds unreasonable. In fact, I called Subaru of America and they told me that its actually one third quart every 1,200 miles which translates to one quart every 3,600 miles. I can live with that and I don't even burn that much and I have over 70,000 miles on my car. I have found that synthetic oil stays cleaner and I like that. What kind of car do you drive?


Tony, one more thing, purchasing a CPO car from a new car dealership with the extended warranty on the whole car to 100,000 miles including all electronics was the best thing I ever did! The savings on the depreciation is substantial and getting a lease return car in really great condition ensures that you won't be upside down in the first couple of years.
