What do you attribute the long life on the water pump on? Coolant and oil changes? What intervals?

I change coolant every 30K miles with peak (long life now called 10x)   I use synthetic oil and change according to my driving situation which is mostly highway.  10-12K miles interval generally or until I am nearing a quart low which ever comes first.  I use ANY synthetic oil and have been known to create mixes of multiple brands and viscosity.

As LU nears 320,000 miles I have had to charge the dead 5yrs old battery that I drained due to leaving the Dash Cam plugged in for 1 week and not driving LU.   I am also changing the oil early (8K miles) as LU is down 1 qt.   Viscosity must of burned off as it was a mix of oils and I think a few of the cheap quarts burned off.   Going with Shell Rotella gas truck 5W30 because that is what I have on the shelf.  Either way LU is still motoring on without any other maintenance.

Well it finally happened.  Lulubelle's water pump failed at just about 330,000 miles.  We have completely rebuilt the entire front end of the 3.5 Duratec with all new Motorcraft parts.   She is now back on the road and running great.   The aim is now at least 500,000 miles on this Duratec if not more.
