My 2018 Boxster will have approximately 5,000 miles on it when I store it for Winter. Should I get the oil changed before I store it even though it isn't due for the free service until 10,000 miles (which will probably occur sometime late next summer)?

How long will it be in storage? I would advise cleaning and waxing (sealant wax*) then car cover. Make sure the gas tank is full (helps avoid moisture collecting int he gas tank), and use a battery tender to maintain the charge. I would also make sure you have correct tire pressure to avoid flat spots but if less than three months that should not be an issue or can use garage floor tire pads** if longer than 3 months. Some people put a cloth or steel wool in the exhaust to avoid unwanted critters but just remember to remove it when you re-awaken the car from it's winter nap.

* I prefer using Meguiar's wax sealant.....have tried the carnauba waxes to include Pinncale II (paid 50 USD total waste of money) but they are absolute dust magnets and they don't last as long as the sealant waxes.

No need - the oil will not break down over-winter. Fuel stabilizer for sure. Some stabilizers can go into crankcase as well (eg., Seafoam) but probably no need.

Fortunately, I have not had to think about storing a car for the winter in a long time. Question for those who do............the fuel that most of us have to deal with contains ethanol.........I think that Stabil or another fuel stabilizer brand is out there that is supposed to reduce the impact of ethanol on rubber components in the total fuel system path?

It will probably be in storage (in my garage) from December through mid-March depending on the severity of our winter. I have a cover and will be purchasing a trickle charger (Suncoast sells one but I am also looking at the local auto parts stores). I plan to buy tire saver ramps (thanks for the reference to Bunkerwall).

If it's only 3.5 months then only change the oil if that is your preference it's not necessary for that relatively brief storage.

STA-BIL 360 is the best product I know of that handles the ethanol content. Make sure you run the car for a while after adding it to your gas tank, as you'll need to distribute the product in the gas and get some of the stabilized gas all the way through the system for it to be most effective.
