@markofexcellence5209 Oh, here go with the internet qualifications and degrees. What systems do you specialization in? Clearly it isn't powertrain-related. I never said the Expedition had only direct injection, did I? Read slower. Dual injection, of course, doesn't equate to being easier to service or last longer. It isn't. No engineer I've ever met would fail to understand how more systems embedded into the engine and less strict manufacturing techniques, design, and materials, lead to less longevity in engines. The UZ/UR engines began life in the $1 billion-plus dollar LS400 program in the late 80s and has been refined ever since. They are proven beyond any modern Ford V6 including the new D35 (which also has a twin turbocharging system that incurs a physical certainty of not lasting as long as the engine itself without replacing something like the electronic wastegates).
The 3UR-FE used in the Tundra, Land Cruiser, and LX570, has only the very refined and simpler technology of port injection, but the FSE series, like the 1UR-FSE used in Lexus and other products, has dual injection. Would you like to know which company pioneered this in gasoline engines? Yes, Toyota did: A technology designed especially for "longevity and efficiency" by Toyota for the 2005 GS450h (now called D-4S). Of course Toyota were also first adopters to now-common tech like variable valve timing yet still managed to make it perfectly reliable. Tell me again how Toyota lacks progression.
