2003 Mercury Marauder, currently just under 25,000 miles, which is when it will get its second fill with M1 5W-30...
All previous OCIs were at 4000 mile intervals until 20,000 miles, which was the first fill with M1 and my first UOA...I'll do another UOA at this change, too, just to see how 5k vs 4k looks. Once the car is out of warranty (36,000), I'll start extending the OCI to 6k and then 7k...
