Other than placards, no modifications are required. A
small placard is attached to the engine and “stick-on”
placards are applied to refueling ports. In addition, there
is a short AFMS supplement added to the AFM or POH.

Current best estimates are that G100UL avgas will cost
60-85 cents/gallon more than 100LL as the fuel leaves
the producer’s facility and begins to enter the stream of
commerce. Estimates are based on crude oil pricing at
40-60 dollars/barrel, and will vary with the price of
crude oil.

Spark plug maintenance and replacement intervals will
be improved in the absence of metallic deposits from
lead. In addition, it is likely that over time oil change in-
tervals will double. Without the lead, it is likely that a
synthetic oil will become available and that will further
increase oil change intervals and reduce the hassles as-
sociated with oil changes.
Momentan liegt der Crude-Preis eher bei 80-100 USD/barrel, entsprechend wird der Aufschlag wohl eher am oberen Ende der Schätzung sein. 20-30 Eurocent pro Liter könnte am Ende rauskommen, so als Grobschätzung nach diesen Angaben.
Nach dieser Liste vom Oktober (könnte mittlerweile veraltet sein) ist der Lycoming IO-360-A3B6D der Mooney M20J leider noch nicht unter den zugelassenen Motoren. (Anderswo liest man, der IO-360 sei dabei.). GAMI schreibt in seiner Q&A generell dazu:
According to a carefully planned agreement with the
FAA, a small number of Lycoming engines and Cessna
airframes were selected for the initial Approved Model
List. That list is designed as a “place holder” list for a
much larger spectrum of Lycoming and Continental en-
gines that will be added as the AML expands over the
next nine to twelve months.
