    Durablend engine oil

    So I had my engine oil switched by the shop I always use and the past 5 times I had been there they put in full synthetic.

    For some reason these morons decided to put durablend in and stupid me I didn't check until I was going through my records today.

    I drove 1600 miles with this do you think I could've damaged my engine with this oil?

    Do the specifications for the oil used match those dictated by the manufacturer's owner manual? Check the specs.

    Re: Durablend engine oil

    It was 5w 30 I know that is within spec. Or are there other specs that I need to know? Also if I know my car is never gonna be under 20 degrees F does this mean I should go to 10w-40?

    In the manual, the specs are listed and there is a temperature vs. viscosity chart.

    Re: Durablend engine oil

    Okay so the the durablend should be fine because its the right viscosity. I couldn't find API specs on the durablend however

    Are you under warranty? If not I'd not worry. Keep the level correct and live life.

    Re: Durablend engine oil

    I'm not under warranty I was just wondering if there could have been a major problem with this oil.

    Durablend engine oil

    If the specs match the oil is correct. If they don't it's not. The best way to determine whether the oil is OK is a post mortem tear down plus used oil analysis. Since your motor is OK only the latter is even remotely practical though I'd not bother, nor would I worry. Keep the level correct and if it gets to you psychologically just shorten the drain interval. Life is short.

    Probably, but probably NOT because of oil... If it's not a full synthetic just make the next change at 2/3 interval.
    You can't have everything - where would you put it?

    Probably from the oodles of spark knock your car has endured.
