Did an Oil Change this morning with gumout/seafoam followed by some fresh Mobil 1. Picked up a K&N Oil Filter as well. Swapped out fluids, lubed up the seal on the new oil filter and tightened on - but not too tight. Turn on the car to drive my car down off the ramps and hear a loud SWOOOSH and watch my oil level gauge drop to zero in about half a second. Got the spill taken care of thanks to the help of a pressure washer and a few jugs of some great chemicals (trisodium phosphate and muriatic acid). Check out the underside of the car to see where the leak came from and the rubber gasket on the oil filter cracked and half had shot out and was hanging off to the side. Will NEVER purchase their oil filters again.
