In reply to my previous posting;The oil level gauge on the dash seems to register appropriately with the stick readings. Of concern is the oil level displays its highest readings on a luke warm restart. It actually displays full peg for a couple of seconds then drops to a normal reading (1/2 to 3/4 scale). We have been keeping the level about an inch below full (1 1/2 qts) to avoid any more oil in the intake. On cold starts the tank fills immediately on start instead of waiting for the thermostat to open, just not as high as on a 150 deg F restart. So the question is why does the oil level behave differently from a 911SC or any previous 911? Normal or abnormal?
