It’s parked underground but not temp controlled by any means. It’s cold in winter but not parked outside.. I will only drive for pleasure in the winter months in NJ.. never in rain or snow but do when it’s dry and cold. The last oil change was not detailed on the receipt or window sticker reminder, all I know Is it was synthetic.

I ask this, as I look at oil viscosity requirements as stemming from the environment your car sees, not simply the outside temp. If your car sits in a garage that never goes under 50 degrees, then it's seeing 50 degree oil when it starts. Conversely, if you park your car outside all day while you work and you have 0 degree days like we have in CO, you need to use oil that's appropriate for this environment.
2) what oil (brand/viscosity) do you currently use? I'm a big proponent of "if it ain't broke, don't fix it" -- while I agree that $375 for an oil change is crazy expensive, doubt that the price is primarily being driven by $20 per quart oil . . . .
I've personally been happy with the Brad Penn 15-40 partial synthetic my mechanic recommended after performing a top end rebuild on my 3.2 -- At over 100k miles post-rebuild, I'm still getting over 2k miles per quart of oil. Recognize that 15 weight is thick for LOW temperatures, but keep my '86 targa in a heated (50 degree plus) garage at home and treat my 911 very gingerly during warmup when starting up after the car's sat in my office's unheated garage at such low temps for a day.
