Can someone help me

[avbw]

I brought in a 964 but lost the owner manual, can someone tell me what are the gear fluid and limited slip oil I should use for a 1992 Carrera RS (which is same as 1994 RSA engine). Thanks.

I see no distinction made for a LSD.

Mobil Delvac. No need for an LSD additive.

I used Mobil Delvac 75W90 one gallon in mine, works fine. Got it at the local Graingers.

The LS stands for Limited Slip.

The G50 needs a synthetic, like the last one above.

Redline is also a good choice.
