    Shop put the wrong oil in. 10w-30 instead of 5w-30. big deal?

    I got the oil changed in my car about a week ago, just prior to a rather long drive on a weekend trip. Everything seemed fine until I was going through some receipts today and noticed on the repair bill it said 10w-30 oil was put into the car. That seemed a bit off and when I checked, sure enough the manual states that the car should have 5w-30.

    Kinda upset by this really... seems like they used cheaper stuff then they were supposed to. Is this an issue? I really don't know much of anything about engine oil, other than the 5w-30 should perform better in cold temperatures... and it definitely gets pretty cold around here.

    Car is an 03 WRX, by the way.

    Unless you are experiencing a fair amount of sub zero cold it is not a problem.

    Change your own to be sure next time.

    If I were you, I'd take it back with the receipt, and the manual. Our weather during march is so unpredictable that I wouldn't risk it with a 10w oil.

    That's what my first thought was. Wanted to make sure it wasn't something insignificant first though... but if it's something that could do damage then I don't really want to risk it.

    I would like to be able to... but I have no experience, very little mechanical inclination, and a dorm parking lot to do it in. Once I have a garage or a driveway again then I definitely want to learn how.

    it's pretty damned easy to do, but unfortunately a dorm parking lot isn't the easiest place to do it
