I supply my own oil to Acura for M.I.D. services. They usually return my 5 quart jug of Mobil 1 5w-20 with about 1/2 quart still in it. I use the remaining 1/2 around +3500 miles down the road since I burn about 1 quart between M.I.D. services on my 11 MDX with +125,000 miles). I just make sure I never go below the bottom mark during my 8000-9000 oil change intervals.
I've notice I need to keep the MDX perfectly level for an accurate oil level read. It can look to be 1/2 - 3/4 low if I check my oil on my driveway with a gradual increasing decline compared to my level garage.
