My car is operating correctly but I recently found this on the underside of the car. I don’t know if what I am looking at here is simply something that got splashed on by the road or whether this is a blown gasket or seal or what. I took a swipe at is with some cloth and it is oil/grease not transmission fluid. There are no other signs of leaking anywhere on the car or on the ground.
A visit to the mechanic or the car wash?
