Just to clarify... SOA considers anything more than 10.7 oz per 1,200 miles (1/3 qt) abnormal. We have been replacing short blocks left and right.

My Moms Forester (2013) is going in next week for shortblock replacement due to excessive oil consumption.

Anyone think the oil consumption issues might be due to newer cars using 0-w20 oil vs. 5w or 10 w of the olden days?

I may be wrong, but I thought it was due to the bottom piston rings....

Its part of the cause for sure.

You can put thicker oil in these motors without harming them. You will just see a very slight decrease in gas mileage.

Yes, you're right, Subaru issued *four* TSBs (02-143-13R, 02-144-13R, 02-147-13R, 02-145-13R) that were basically about replacing oil control rings for both FB20 and FB25.
But, like Blur125 said, that didn't work so well for all concerned engines.
So, now, Subaru has issued another TSB (02-157-14R) calling for the replacement of the entire short block (IMO, a much better solution).

See the Oppo/Jalopnik post about this: http://oppositelock.jalopnik.com/sub...ion-1600566355

Buick: after fifteen years, we had to start topping off the oil between changes to make up for the puddles it left on the garage floor.

Given most modern engines don't burn oil until you put a lot of miles on them, there's no reason to expect to have to top off a new car engine between oil changes.

I'm glad someone else agrees with me.

Default Oil Consumption Poll

2014 XV build date 01/14
2900-32,500 I had the light come on in between changes. When it first came on at 2900 I was not alarmed, most all new cars burn oil between changes. All my consumption issues seem to have stopped. Have not seen the light since the 32,500. I've never once taken the car to the dealership. I have 43,791 on the car I'm pretty sure she's done burning. I did play with 5w20 and noted 21.3mpg. The oil I've been using since the consumption stopped is Mazda Genuine 0w20 with Moly. My last change 32,500-41,331 nothing burnt or low.

I've been following this thread with interest (from afar obviously) and for what it is worth I have a '14 Impreza 2.0 that is now 1500 miles past the first service and there is no indication of oil consumption - my average fuel consumption is in the order of 33 mpg(US).

Agree with both of the above. I had a 1993 Camry with 200k miles that didn't burn oil at all. A maxima with 150k that didn't burn oil at all. Really no one I know outside of the tuning community considers it normal to top off a new car between oil changes.

My 2014 WRX with 13,000 miles on it has burned over a quart in the less than 6000K mi. OCI that the Subaru dealership has me on - a little spirited driving, no racing and vast majority just daily driving.

I'm glad someone mentioned that SOA considers 1/3 qt in less than 1200 miles to be excessive, not sure if I hit that mark or not but will ask the dealership for a consumption test as recommended.

My oil light came on before 4,000 miles, and turned off after a few minutes.

A week or so later it came on and stayed on, at roughly 4,000 miles. I put an entire quart into the engine and the dipstick was showing the oil level in the middle of the high/low marks.

If you rely on the oil light to come on to tell you when you should add some oil you should not be driving a "car". Basic maintenance means checking the oil in the engine at least once per week maybe twice depending on the miles driven per week. That means "making" time for this 2 minute check. If you had read this entire thread you would of seen that checking the oil in the engine needs to be a priority, period. If you want to keep using a 0w20 oil, then give the Mazda 0w20 full synthetic with Moly a try for a while, it is good stuff.

Who suggested for you to use the Mazda 0w20 oil? I would be quite the scene to stroll right into a dealership and tell the service department that your oil consumption stopped after switching to a "better" 0w20 oil and that it was from a Mazda dealership...

I doubt mazda manufactures their own oils. Its just another brand, relabeled as mazda.

I'm not sure who does but their engines are using similar ideas with low friction and 0w20 with no issues. I am a spirited driver.

Edit: Idemitsu manufactures it

There is one in Roseville, CA, and I believe they share the same service department. I don't recall as I stopped going there...their service dept sucked

I figured I'd post up about my mom's 2012 Impreza 5MT base model. Currently sitting at 44,000 miles and using 2.5 quarts between changes (her Subaru dealer did a consumption test and it failed). She also noticed her oil light would come on every so often. When this happened she would turn the car off as soon as it would be safe to do so and would add oil until at the acceptable level. I recommended she keep a quart in her car at all times.

Subaru is replacing the short block for free, no charge to her. Not sure what the warranty is, but I thought it was 3 years on powertrain? Either way I'm glad Subaru is helping her out. Unfortunately, I think she'll be trading it in for a 2.5L equipped OBS as she misses the torque from the EJ.

Did you mean 2012 Impreza? Pretty sure the EJ25 was in the 2011, and even then, it wouldn't be a short block replacement, but more likely a head gasket.
