We also have a 2015 Forester. At about 45000 miles we started seeing oil usage. We were given the run around. Did the oil consumption test. We found they gave us an extra quart of oil we we got home. Documented it and took back after 1200 miles. They checked it and said, "oil level okay, no usage" we said, well, we documented that you started the test with an extra quart of oil! Oh I wish you would have told me that, now the test is void. We will have to do it again.. He says, "people make mistakes.. Lying, you know what! Good thing is, I documented an oil loss greater than their limit, 1/3 quart/1200miles. So should get new short block after this test. I can't tell you the amount of deception that we have been through! Will not purchase another Subaru.
