I searched around for "highest mileage 3.5" but the only thread that I came up with is closed.
I realize that my truck is not really that high in mileage but it's a start...
2018 502A Lariat 4x4 with 130K miles
This truck gets an oil change every 5K miles with Motorcraft semi-synthetic oil and Motorcraft filter.
58K miles - Rear brake pads (Rotors turned)
80K miles - Plugs done
95K miles - Oil pan replaced under extended warranty. (Plastic lower pan)
99K miles - Cam phasers and all related components done under extended warranty. Newest, closed face, phasers were installed, I paid for all new parts the warranty wouldn't cover including water pump even though it was good.
100K miles - 180 degree Motorcraft thermostat installed once extended warranty expired. (Best mod ever)
100K miles - Full transmission fluid exchange. (filter untouched)
100K miles - Transfer case and rear diff fluids changed.
115K miles - Entire AC system replaced due to bad compressor. Battery junction box was also replaced due to a flaky, non-serviceable, AC relay. (Probably what took out the compressor)
116K miles - Plugs done again for fun. (nothing wrong with the old ones)
120K miles - Front diff vacuumed and refilled.
150K miles - Full transmission fluid exchange. (filter untouched)
