100,00km? I'm at 119,000 miles (191,511km). Replaced a failing throttle body, everything else was maintenance (plugs/boots/filters/fluids/rotors/pads).

Anyone know if I can expect the same from the 3.5 ecoboost?

Guy I do business with has 400,000 mi on his '13 with about 20% of the mileage pulling a 5,000 lb trailer. Still no add oil between oil changes. Oil changes average every 8,000 mi or so with MC Blend (in other words nothing special) and other than a few sensors and a throttle body (A little over $100) just normal.maintenance items. Still has the original turbos and timing chains. It's a Screw 4x4 with 3.31 Gears.

I haven't thought to ask if he has ever replaced the IWE Solenoid. or balljoints as we usually talk about how the engine is doing.
