Have read the owners manual - no details
Have searched and many threads on the oil topics and they seem to raise more questions...
It appears the 996tt also uses 75w90 with certain specs and there's a P approved brand/sepc. My quetion is: f the oil specs surpass, is it fine to assume it is fine to use. To specify the question does not ask which is "best".
Has anyone here tried omega 690 oils in their 996tt?
I've used this on all my track day cars with great success and prefer to stick to what I know works. nsx/s2000/lotus 6spds/LSDs and in the nissan gtr 5spd. Power ranges 230-730hp.
thanks!

hmmm... how about other non-approved 75w90 mission oils such as redline shockproof, motul gear/LSD oil?

 

I just use the OEM Mobil 1 or the Delvac M1 product. These are NOT the same as the stuff in Pep Boys of the same weight.

Search..there was a thread. I get mine from Lufteknic VA.
