Almost the same as securityguy!
Did the first change at 1300 miles, second at 5800.
4500 miles and level hasn't changed.
Filled with Penzoil ultra platinum 5w-30 and going the full 6000 miles and then an oil analysis.
Feel comfortable going the full 6000 miles with a good synthetic and the 6.9 quart sump on the 3.6.
