Ah, but we're dealing with humans vs. computers so concepts like reasonableness and context come into play. Humans love context.

Arguably, if you pose a question that can only have one answer it's reasonable to assume that a response of 'It's not X' infers that the person providing the answer may either know the answer itself or know a little bit more about why they know it's not X that could be helpful to the person seeking the answer. The obvious exception to this is if the initial assumption of the questioner is so far off base that absolutely anybody could know it's wrong and thus answer negatively without any orienting information:

Q: How far is it from the earth to the moon? Is it 190,000 miles?
A: No, that's not it. I don't know the actual answer but I'm pretty sure it's more than 200,000 miles hence I know 190,000 can't be right.

Vs.

Q: How far is it from the earth to the moon? Is it 15 miles?
A: No. No it is not, sir.

Humans like context if it's available, which it always isn't. Lifeless objects don't care; hence Susan probably doesn't care.

 

C'mon, I know she's not that pretty, but to call her lifeless? That's just harsh!

 

LOLOLOL

 

Well, she is pretty h0t in her own inanimate way

 

We're two pages deep, and I still have no idea what gear oil is on the transmission.

 

Hey, but at least we know what it's not

 

Except I answered the question.

 

Use Mobil 75W90 LS.

 

Please don't. Its too slippery.

 

That's what Susan said.

I heard it's "3 in 1 oil."

 

Figured I’d revive this old thread as well.

I am about to have my transmission reinstalled into my 2016 Spyder - it was recently regeared with new gears 2-5, new main shaft, and upgraded differential. The shop reinstalling it is different than the shop that rebuilt the transmission. The shop reinstalling it is not expert on this car and would be a first time for them on this model, but they are Porsche people and have removed and installed transmissions forever but mostly on older or different Porsche models. We have the full workshop manual with torque specs etc for this job.

I am absolutely confounded on whether to use Motul Gear 300 105777 or Motul Gear 300 105778 oil once the transmission is reinstalled. And since there’s misinformation out there, I am the one who needs to solve this without relying on the shop since the misinformation that confronts them is the same misinformation that confronts me.

Various reliable web sites say to use -777. And the -777 cross references to the OEM part number for this car. Is it the case that the OEM oil does not have a limited slip additive?

Various other very reliable web sites and expert Porsche people say obviously we want to use the LS variant because the car has a limited-slip. The shop who re-geared the car said they use the LS variant in all their re-gears. I note that post #24 here said NOT to use the LS.

I don’t like arguing with manufacturers, and I also listen to smart people in the aftermarket business.

Does anyone know what I should be doing here?

Thank you very much!
