    Possible to have an Add Oil False Alarm

    Okay, here's a dummy type of question about engine oil. I know there's lots of threads about oil consumption, and I've gotten used to adding about half a quart of oil in between services. I did so a couple of weeks ago when my "Oil Low" warning came on - which would normally tide me over until the next service appointment.

    However, today from a cold start I got another "Oil Low, Add Oil" message, so I added another half quart. However, when starting her up, I'm still getting the add oil message. Checking the dipstick, it seems like there's sufficient oil (although it can definitely use a change). Is it even feasible this message could be a false alarm?

    Sensors can fail, don't just add oil because a light is on. The dipstick is the deciding factor, it won't lie.
    You probably have a sensor going bad. If you just changed the oil wait until you need to change it again and then replace the sensor.

    What does your "% of oil use left" indicate?

    1/2 quart between the normal 8 - 10K for the change reminder near 0?

    I had the same thing happen to me recently. Checked the dipstick and it was plenty full. Took the car in to the dealer today and they said it was not low, but that it was probably just time for an oil change (even though I wasn't due yet). I think maybe they forgot to re-set the indicator last time they changed the oil for me.

    Re: Possible to have an Add Oil False Alarm

    Hi Folks, thanks a lot for the recommendations. I've been traveling for a bit but will be taking it into the dealer soon to have them double check the sensor. The oil did look pretty dirty, so it's time for a change anyway.

    % oil life is reported at 48, and level is not full. Probably user error, but it gets to halfway on the crosshatch, then there's a gap, and then some at the top of the crosshatch - I'm assuming at the top, it's splash back because I'm yanking it out too fast or something.

    not trying to sound like a douche but are you pulling the stick out, cleaning it, and putting it and out nice and easy?
