Finally, your average car owner in the US is not the best when it comes to maintenance and will run an engine long past its oil-change point.

Manufacturers themselves recommend crazy long oil change intervals, with 10K or longer, because, you guessed it CAFE and EPA regulations count oil changes against your lifetime emissions.

Thinner engine oils cause less friction between the components of an engine and result in a lower amount of energy loss from the movement in the engine, but engage reduced oil film thicknesses, which requires higher tolerances and better oil or it will generate more wear and limit durability. Basically manufacturing techniques and oil chemistry does not yet allow reliably do what is necessary. What they have now is similar to low-yield chip fab process, only they have not developed a good way to test it before installing the engine.

the reason gas prices have been stable is we keep pushing for more fuel economy keeping demand down.

Absolute bullshit. a) Gas prices have no been stable; b) It is supply side that largely fluctuated, not demand; c) The biggest contributor to lower gas prices is the U.S. shale revolution, where a new technology allowed US-based production to increase.
