I wouldn't necessarily emphasize this point; do try and make sure your car doesn't leak anything, but at the very least make sure it won't cause any problems for others on the course.

 

like I said, as long as its not pouring out or dripping quickly, they wont notice.

If you can leave your car overnight and it drips a drop of oil, then i wouldnt worry about it.

If you leave it overnight and you hav ea puddle, then I'd look into getting it fixed.
