Well, the car is on sandy, dark ground, but next time I go out, I'll move the car and see what I can see.
Is the oil in that section of the car from the same supply as the engine oil? I used to know what I was doing under the hood of a car, but that was decades ago, and I have no clue what's under the hood in this "new" car! In my day, we used to do lots of the stuff ourselves, and now I can't recognize anything under there....The online photos made no sense at all. I'm old, I guess....sigh...
I do get regular oil changes and nobody has ever said I was going thru lots of oil.
