You won't know until you try it. 10K miles on conventional is pushing the limits of common accepted wisdom, but if it's steady highway miles, no towing, and southern summer driving, it should be fine. if the motor uses 1qt in 10K miles, you might want to delay the first "top-up" until 4-6K miles, to inject some fresh oil into the sump when you are half-way to the next change. Top-up "and then some) again at 7-8K miles to do the same.
Keep an eye on the oil monitor, but if it triggers at 11K miles with your use, you should be good to go.
I've heard of some people using extended drain intervals, and changing the filter-only, at the half-way or 2/3-way point, and topping up the oil, as the filter will fill to capacity before the oil loses its additive package in most cases.
