OP here.
Thank you everyone for helping me out. It's a lot of mixed information since everyone has different geographics and model year etc.
I put in some Pentosin MTF2 (super expensive btw) today and went for a short test drive..... I am very happy. 1st gear had only hints of notchy-ness (is that a word?). The difference was felt just pulling out of the driveway. For the most part my problem is 80%? solved. I'll update once I get more mileage.
Now help me understand why Pentosin MTF2 75w-80 is better in cold temp than Redline's mt-90 75w-90 when both have the same winter weight... (Maybe I should had used this for my (RIP) 944 S2 with the near same issues; and got used to it as I thought the car was just "old". )
Anyway, which part of the data sheet should I be looking at to check this cold affected nuance?
