Out of curiosity, when you check your oil should it be at the FULL line when the engine is warm and the oil has been pressurized or when it's cold. I've read that it should be FULL when you've got some oil pressure. I ask because I filled to full while the oil was pressurized but happened to check it the other day when everything was cool and the oil level was just a little under the full line (3/4's up to full). At first I thought I had somehow lost/burned some oil but then I warmed the car up and it was back to full. Probably doesn't matter, just curious.
