My 2013 Forester failed the oil consumption test at my local Subaru dealership but Subaru denied me any accommodation because I don't have all of my oil change records. I work at a school and have had my oil changed religiously at the school auto shop under the supervision of a certified mechanic. The car burns more than 500 ml per 2000 km. Any suggestions or recourse? I am worried about premature engine failure does anyone have any suggestions about what oil to use? Should I sell the car? Trade it in? Obviously very disappointed in the Subaru brand at this point. Thanks for any comments.
