We have two F-150 2.7 Ecoboosts. I have been checking the oil extremely often since we bought them. I was sampling the one today, and I checked the oil before started it, after it had been setting all night ( about 33 deg. F.) I have checked it after setting overnight before, but when temps were in the 50's or 60's overnight. I noticed then, as now, there is a huge difference between hot and cold. Even more so today. It is consistently a quart less reading off the dipstick when dead cold compared to 20-30 minutes after shutdown when hot. I think this is probably the biggest disparity I have seen on one of my personal vehicles.
