My 2000 outback wagon has only 67k miles. About a month ago, the check engine light came on. I took it to an Auto Zone and although unforutunately I didn’t write down the code, the person who checked the car seemed to think it was probably just a bad tank of gas. I ran through that tank of gas and filled up with premium gas. Light didn’t go off until THAT tank was near empty. Filled up a third time and light remained off until tank was near empty and it came on again. It has not yet gone off. I’m not sure how many more tanks of gas I should run through! The car isn’t running poorly so I thought the bad gas was a good explanation.
A side note: about 6 months ago I had to have the head gasket replaced. I argued with Subaru and got some extra work done in exchange for the head gasket payment since my car missed the recall by a few digits but I was obviously stuck with an inferior product. I’m hoping they didn’t do an inferior job. Even though it was 6 months ago, it wasn’t that many miles ago - you can see my the year/mileage on my car that I don’t drive a lot.
Any ideas other than to take it in? Does that gas explanation sound reasonable? Anything about a head gasket related?
Thanks in advance for your comments.
