The Porsche gear oil is full synthetic and out performs all other lubricants - including a non Porsche approved oil like Royal Purple.....
The OPC filled my gearbox with Mobil 75W90 when I bought the car @ 60,000 km - I was never really happy with the cold gearchanges, so at 70,000 km I replaced the lube with the genuine Porsche oil - a real improvement in shift feel and quality.
Its not cheap, but it lasts for 90,000 km, so it has to be good !!
No alternative oils for me....
