2011+ FB25 oil consumption usage data and updates (split thread)

Please use this format when reporting oil consumption.

How is the consumption from?:

1. 0 miles to 1,875 miles.

2. 1,875 miles to 3,750(severe service interval).

Then for those continuing on and doing the normal service interval.

3. 3,750 miles to 5,625 miles.

4. 5,625 miles to 7,500 miles.

I don't mean total accumulated consumption at those points either, just consumption from point to point with a notation for make up oil amounts.

So it would look some thing like this:


Oil brand, Mobil 1 Oil type, Advanced Fuel Economy(AFE) Weight, 0w20
Consumption amount/make up amount added

1. 0 miles to 1,875 miles. 0/0

2. 1,875 miles to 3,750(severe service interval). ¼/¼

Then for those continuing on and doing the normal service interval.

3. 3,750 miles to 5,625 miles. ½/½

4. 5,625 miles to 7,500 miles. 1½/0(you're changing it why add)

Total consumption = 2¼qtsMake up = ¾qt

I say this way because following some of the forums I am seeing some members average it out to a linear consumption rate when it is not. They are using nothing or little from oil change to 3,750 but between 3,750 and 7,500 they may have added 2qts and are reporting they are seeing consumption of around ¼qt / 1,000 miles.

To me seeing a non- linear consumption rate like that would seem to be a likely indicator that the oil is contaminated, additives are breaking down, volatility is going up... and no longer able to do its job and one should think about shortening their OCI on that particular oil and with those driving conditions to maybe 5,625.

Following a layout like this allows every one to see the oil brand, type, weight being used and when the consumption is occurring.

2011 is burning a lot of oil (Premium- non turbo). It's going into the dealer but he told me the owners manual states that 1 quart every 1, 200 is "acceptable." Are they trying to cover themselves by putting it in print? I didn't even get the manual until after purchase. I think it is burning more than that but even 1 quart every 1, 200 under light driving conditions (no excessive weight and no towing) is clearly not acceptable. Why should a brand new engine, now with about 10k on the clock be burning about a quart a month- minimum. So according to their math, if I can go 7k between oil changes, I will have had to add about 7-9 quarts or oil before I even do my oil change? This makes no sense and gets costly fast since it requires full synthetic 0w20. I can only imagine this issue will get worse as the engine gets older too. This is not what I expected from a new vehicle. You buy a new vehicle to avoid these issues. I have another 10 year old vehicle (not a subaru) that has never burned a drop.

Has anyone else in here been burning this much oil- about 1 quart or more every few week- or about every 1, 000. What can I do to address this with Subaru directly if the dealer tells me it is within the acceptable range. Have there been any recalls on the '11's to address this issue? I was not told about this issue prior to buying the vehicle. I don't even think it's good for the environment to be putting a quart of oil into the air every few weeks. Many cars can go 5-7k without burning a drop of oil. Is it just this Forester or are all the 2011's with the new motor burning at such a high rate.
