I would recommend that @malthusunc read the manual on the Jeep (likely available online before delivery) and follow those instructions.Given your scenario I would put Stabil gas stabilizer in her tank. Gas goes bad and can cause troubles in your fuel system.
First, most auto manufacturers recommend no additives of any type go in the vehicle. If an additive is needed, then the manufacturer will specifically call it out.
Second, the auto makers address this with the design of the vehicle. Our 2018 Fusion Energi was designed to monitor how often the gas engine was used, and would run the gas engine to prevent fuel problems. Also, the fuel system was pressurized to prevent air entering, and you had to hold a button for the system to depressurize and the fuel door to open.
Fuel Freshness Mode (If Equipped)
This helps keep the fuel system functional and the fuel fresh. If you mainly use your vehicle in electric power mode without refueling, the gasoline in the fuel tank may become stale due to
aging. Stale gasoline can damage the engine and fuel system. Your vehicle automatically switches to fuel freshness mode if you do not refuel your vehicle with fresh fuel within an 18-month period. Fuel freshness mode protects your vehicle from potential engine and fuel
system damage caused by using stale fuel. Note: If you do not add new fuel during an
18-month period, fuel freshness mode will use fuel until approximately 1.2 gal (4.5 L)
of fuel remains in the fuel tank.
During fuel freshness mode:
• The information display will indicate fuel freshness mode is active.
• The vehicle will only run in hybrid mode. EV Now mode will not be available.
• Most of the plug-in power will be stored until fuel freshness mode is completed.
Note: EV Now mode resumes when less than 1.2 gal (4.5 L) of fuel remains in the fuel tank.
Note: When the fuel level is less than one-quarter full, refueling your vehicle will end fuel freshness mode.
Note: We recommend you use a fuel stabilizer if you use less than a full tank of fuel during an 18-month period.
