Federal standards do not cap aromatics this tightly.

Sulfur Content: While federal standards now match California's ultra-low sulfur limit of 15 parts per million (ppm) for highway diesel, California pioneered low-sulfur requirements decades earlier and maintains strict enforcement.
NON SEQUITUR
Lubricity Standards: California enforces a specific lubricity requirement (a maximum HFRR wear scar diameter of 520 µm) to ensure that removing sulfur and aromatics does not cause excessive wear on fuel injection equipment.
covered by a very long line of synthetic lubricants available on the open market…
Renewable Diesel Mandates: California requires specific fleets (such as public and certain off-road or transit fleets) to use high-purity renewable diesel formulations like R99 or R100 under its Alternative Diesel Fuel regulations. [1, 6]
IOW, biodiesel, which diminishes fuel economy, hence negating any above listed gains of fuel economy via synthetic lubricants…
