Only if her lube does not contain impurity.
I use Mobil Delvac 75W-90 in my Cup and really smooth out down shift in my sequential

"Original fill in 996/997 GT3/Cup cars, and GT3Rs. Works well in all 901, 915, G50, G96 gearboxes. Used extensively in Porsche Motorsport products in every grueling test there can be LeMans, Sebring, Daytona, etc. We also use it in our service department in all street and race cars. Works in cars with or without (LSD) limited slip differentials"

OK, available are either Mobilube SHC 75W-90 or Mobil Delvac Synthetic Gear Oil 75W-140. Which one from those two? Or is Mobil Delvac Synthetic Gear Oil 75W-90 better than those two? How about PTX?
Rebuilt box with CUP's LSD, otherwise more or less like 996 GT2.

Pete,
SHC is the Euro branding for Delvac these days. Only difference between the two oils you mention is viscosity. PTX has some friction modifiers for cold start shifting. Any of the three mentioned would be fine in your car. Big question would be percentage of track versus street percentages and ambient temps.
