From experience and fact i realized that putting in anything higher in octane than what your vehicle actually needs is just wasting your money.
More specifically, what the vehicle is tuned for.
Used to be a turbo or supercharger automatically meant 93 octane period. Now, Ford's got the tuning worked out between the ECU/Spark tables and variable timing to where they can make the 87 work.
The engine should be able to adjust, minimally, for 93 octane but you won't see any earth shattering differences. As noted it may seem smoother and the throttle tip-in might be quicker.
If/when tuning becomes available for the Lincolns, the tuners can take advantage of the upper limits of the 93 octane world and go a little beyond what Ford allows for, while still remaining safe. With these direct injected turbo-and-variable-timing engines, an ECU tune can produce massive amounts of increases.
Now, if only they'd release a Lincoln spec'd Explorer counterpart with the new 400hp 3.0L twin turbo....
