I bought new a 2014 Forester
I bought new a 2014 Forester which now has 26K on it. It burns oil so I took it for a consumption test. They change the oil and overfilled it about a1/4 qt. I detected that and had it documented then came back after 1200 miles. It was about 1/4 of a qt low, so about 1/2 a qt in 1200 miles. To check the oil they make you wait one hour so it all drains into the oilpan. This causes it to read higher on the stick. So they can justify not doing anything. Who can wait an hour to check there oil if you are at a gas station.
Bottom line is they are tricky and play games to show the engine is not using much oil. I used to work at a dealership and they don't like warranty work because they don't get reimbursed at the retail rate but way lower.
I plan to just keep taking my car in and complaining about and documenting what it uses as best I can.
This is my seventh Subaru and my last if they don't fix this.
