And expect people to not answer the way you want.

You asked about a topic that is debated strongly on all on-line Porsche forums with differing opinions, no one convincing the other side. And then you ask "what is the answer, just give it to me in the condensed version".

The true answer is there is no consensus answer on the "right" brand or viscosity (and IMHO, given your CT location, lots would depend on if you were storing your car for the winter and only taking it out on its summer tires when the weather had been a healthy 45 degrees for a couple of hours or you were intending on driving it through the winter. You say rarely used in the winter..does that imply the former? Because 15 weight isn't the recommended for cold starts. Fine in the summer.).

Porsche must list about 60 answers in its approved oils list.

I live in NC, lots warmer than CT where my sister in law lives. If my oil filters get here today, I'll be changing my '01S to 10W40 fully synthetic. Not Mobil. I follow the not under 45 degrees rule as I have only summer tires but have been out on Xmas day with the top down as down here it isn't like your deep freeze for long periods weather...I get out at least every 2 weeks. Still I like the 0 or 10 weight for a car that isn't run every day as it flows more quickly when the car is started even though the car is never ever started below 40 degrees.

But that is only one man's opinion.
