I too have been filling with 6 qts to get to the dipstick full mark on my 2011 Edge. However, at 20K I checked and replaced my air filter, and found a considerable amount (more than a tablespoon) of oil pooled up inside the intake tube. It was clearly being drawn in from the breather tube connected to the top of the valve cover. Cleaned it all out, and changed oil using 5.75 qts (middle of the crosshatch area). I too am conditioned to see the oil above the 'add' mark. I'll see if it makes a difference.

I've only put 3,630 on my 2011 Edge 3.5L AWD, but have ranged 19.2 - 24.1 with an overall average of 22.1...so far.

I'll throw one out there. Aerospace 303 Protectant is absolutely the best stuff I've found, but it's kinda pricey. I've used several brands/types over the past 30+ years (but not all brands mentioned in this thread), and this stuff works very well, does a good job in repelling dust, and lasts for a month or longer. http://www.303products.com/shop303/index.cfm?category=58

Anyone had an issue with changing engine oil with the recommended 5.5 quarts only to register to the add mark (bottom of crosshatch) on the dipstick? 6 quarts takes it to the middle of the crosshatch on the dipstick. 2011 Edge SEL 3.5L AWD
