As we’re moving into the world of DI (because it’s more efficient), It boggles my mind how in Japan “lean burn mode” is allowed on factory cars, but in the U.S it is prohibited. In theory, oil problems can occur because either not enough or too much oil will be injected into the combustion chamber. Then of course, there will be huge variety in Crankcase Pressure, since blowby will shift from 4 cylinders to 8 then 4 again. Then, the harmonics of the engine completely shift because the crank will be given uneven load from cylinder deactivation. With this I just can imagine increased wear on the crank, more PCV system, terrible harmonics and just less reliability overall.
It’s just overall, lean burn mode is a better idea. Yes lean burn causes increased temps, however it is easy to control with proper cooling and monitoring (only activating with proper oil temps, low load, high gear & low rpm, proper coolant temps, and comfort/eco drive mode).
