PLEASE, CONFIRM IF THIS PRODUCT IS: 75W90 NS GL-5, NOT 75W90 GL-5

I bought 8 bottles for my 355F1 and I can confirm, it is NS.

I have a non limited slip differential. Is it better to use non limited slip oil or limited slip oil?

This answer assumes the differential calls for a 75w90 GL-5 gear oil. 75w90NS should only be used in non limited slip differentials. 75w90 may be used in any differential. Generally, just buy the 75w90 with the limited slip modifiers. The most typical reason for buying the 75w90NS is for racers that want to do a custom mix and add the friction modifiers separately.

Does this gear oil have a built-in friction additive?

The title does suggest it does.

Is this a good product for subarus given the nature of the trans and front diff sharing the same fluid?

its used in o3 Subaru outback in front and rear diff for 30k miles. No problems at all
