Erik is correct in terms of the long term prognosis and it is the accepted conventional wisdom of the Forum. But perhaps they are all babbling fools?
Erik's polymer chemistry may be a bit shaky but he is helpful gearbox mechanic not a chemist !.
What he mean't(I think) to say is perhaps the friction modifiers in the unique additive pack for this "Porsche- spec " Spirax may have a critical function.That additive pack is unique to this spec of Spirax.
The ultimate authority (certainly not me!) on this issue is probably GBox or Forum Members GTgears and JFP. They have previously contributed to discussions on this subject very clearly and in detail.
I mention this so people reading this subject for the first time Search on the 6 speed lubrication subject before they damage their gearbox by using the wrong oil and thinking they dodged the Porsche tax.They might. But they'll get fined for tax evasion!
That said, neglecting the routine gearbox lube change could eventually cause more damage than using a generic oil ?
Without a CMS Shift Arrestor some say any 6 Speed is doomed so perhaps the whole discussion is moot ?
