Ive decided to Keep the 3.0 Mercury Milan Premier i had for sale and turn it into my Daily driver. That being the case it was time to get more familiar with this car and get to know her a bit more (up till now it been my wifes car) and ive only done one oil change last fall. The milan had 7,800 miles on the PP and Napa Gold. I dumped the oil and refilled with the same + same filter. ive never let anything go that long before on a OCI, thats where i feel my atta boy is well deserved. 
I also rotated the tires and checked all other fluids. The only thing that was just a bit low by a few inches was the coolant, from the max cold line.. frankly im not to worried as there was plenty in the Res.
Opinions. Q. I have 7,500 miles as my untested limit. Im not very comfortable going longer, even on the PP. The Milan went 7,800 miles with zero consumption, no top was ever needed. would you feel like you got your moneys worth out of a 7,500 miles OCI or start pushing it out with UOA's ? I feel this limit of 7,500 or once a year if i dont reach that number is satisfactory.
at $20 a pop for UOA's that buys plenty of oil on a car i will likely not keep for another 5-7 years or 100,000 miles.
