I have no idea where my oil could be going because there are no apparent leaks. I bought my subaru used about six months ago and have put in several quarts of oil now. It starts up nice and runs good when it is warmed up. (???) The check engine light came on again two weeks ago and is staying on this time.
My car as a diagnostic appointment next week, which brings me to my next question. Why do some shops only want $25 to run a test where others are charging $70?
