Hi Gelbster,

please compare the oil specifications:

Shell Spirax S5 ATE 75W-90
http://www.epc.shell.com/Docs/GPCDOC_GTDS_Shell_Spirax_S5_ATE_75W-90_%28en%29_TDS.pdf

Shell Spirax S6 AXME 75W-90
http://www.epc.shell.com/docs/GPCDOC_Local_TDS_United_Kingdom_Shell_Spirax_S6_AX ME_75W-90_%28en-GB%29_TDS.pdf

Please compare the kinematic viscosity of the two oils. It's very different. That's why S6 AXME won't work for the Porsche 986 Getrag transmission.

I'll recommend Shell Spirax S5 75W-90.

Best would be a group buy, but you'll need 6-7 people who are interested.

Regards from germany
Markus
