my car has never leaked motor oil ever. today i did a change, put 4.7L of mobil 1 5w30 in and changed it with the proper fram filter (FH3600). after i brought it down off the blocks i noticed there was a puddle of new oil underneath. odd, but id rove it for a bit. later on that day after it sat in the garage for about 4 hours, there was a larger puddle of oil underneath the car, and this time i lost enough to get the OIL LOW light to illuminate. i cleaned it all up and ran the car for a minute while my buddy was underneath looking for any activity. nothing. i put papers underneath over night and this mronign there was no more leaks.......what could this have been?
