I'd look at pre-heating fluids (synthetic, after break-in complete). Same for keeping coolant temps high with radiator cover (winter front) adjustments.
On vehicles specified for work, I think the best plan (past establishing a "perfect" mechanical baseline) is in:
1] Reducing all miles via trip-planning (combining errands, best-order-routing, etc); and,
1] Driving the remaining miles as well as possible.
There is a good deal of depth in those two, I have found. But reducing warm-up time to a minimum is basic to success.
