Same thing happened to me. I
Same thing happened to me. I have a 2009 outback 2.5L non turbo with 86k miles. I was 150 miles from home when I hear LOUD knocking in the engine. I was on the interstate when it happened. I jumped on the exit adapt and luckily there was a car quest right there. After getting a grip on myself and calling around someone told me to check the oil. IT WAS EMPTY. I put 4 quarts in it and now I'm looking for a new engine. Light never came on. Everyone has since been telling me how often I should be checking the oil like I didn't know. Lesson learned check even more. I still love my outback tho
