The check engine oil light lit up on my dash board which surprised me. I thought, I don't have a consumption problem that I'm aware of. I checked the oil and it was only on the stick about 1/4". I added a qt and it took it up to the add 1 qt mark. I added another qt and it took it to the full mark. I drove the car around a while then let it sit. I checked the oil and it was over filled by about 1 qt. Whats's going on here? Does this have something to do with the oil pan design having a reservoir at front and back? Is it possible to have a situation where more oil is resting on one end of the pan than the other and thereby rendering false readings? I can understand a qt low after all the driving I've been doing and that is what it seems to have been. But why the check oil light and why would it falsely take two qts to fill it up when after all it only needed one? Am I ok leaving the extra qt in there? Obviously it's going to consume it eventually anyway.
