Maybe. I looked under and all around the front from under the hood and all looks dry and clean. So, you're on the right track - maybe some under-hood apprearance fluid or similar. I just thought I'd mention it in the event others had seen the same. Thanks!
Hello, I noticed 2 gray stains on the garage floor when we first got the new ā23 Outer Banks 1.5L. Located about under each headlight location. See photo. Any ideas what it might be? They feel dry to the touch.

6.6 qts for the 1.5L engine.
High mileage oils usually have the effect to soften and or swell seals - yet they are still meeting current specifications. I suggest you give Mobil lubricants hot line a call to discuss.

Located under Axle Lubricants. A wealth of information!
This problem reminds me of a check valve that is over-sized. A fix might be to seal off one side thereby making the other side stay open? I wonder if taking them off could encourage air to come in and bring dust and, hopefully not, Carbon Monoxide from exhaust fumes into the car.
If our ā23 OB were doing that, Iād do a precautionary oil change but not really expect it help much. Also keep an eye on oil color (not yellow) and coolant level as some are writing about coolant leaks. Good luck this is disappointing to hear about.
