Hello,

I have extra manual transmission oil 75W-90 leftover from changed my Porsche 996TT. The oil was made by Mobil 1 Delvac Synthetic. Can I use this for my 04' S?

Thanks for the help

 

When I replaced my axle I used part number 83222344589

but check TIS or Bentley for your year

 

I've been using Amsoil Severe Gear 75w90 in my 06 JCW and it's performed well.

I searched NAM for Mobil 1 gear oil and didn't find much,
but this seems important:

On the Mobil 1 site they write:

Applications:

Not recommended for applications requiring API GL-4 level performance

&

Heavy duty non-synchronized manual transmissions, axles and final drives requiring API GL-5 and MT-1 performance

If I were you I'd search more on NAM and possibly geek out looking for relevant info at the bobistheoilguy forum.

 

Thank you for the info....much appreciated.
