Not so much as a drop used. I'm amazed! As thin as this oil is... and as long as it's in there, I thought for sure it would be consuming some. When I did my oil change (myself) at about 8,500 miles, I was shocked to see 3.6 quarts come out (full capacity).

By the way, I've already purchased the Mobil one 0-W20 for the next change. Found it (again) at WalMart in Orange, CA.
