I can't get either locally, so I'm going to pay postage whichever..

Adrian says fully synth is fit and forget. Is swepco synth?

Type 911 have swepco, saying 'transforms any gearbox'...

Or do I stop worrying and go with the 75-90 fully synth from my motor factors?

ian c - u.k

can you get red-line locally ?

With our G50 transmissions, you want a synthetic gear oil as it works better with the Borg-Warner synchronizers. Swepco 201 is the gear oil of choice for 915 transmissions, which works better with the Porsche-designed synchronizers. The synthetic gears oils are more slippery than a Swepco-type of gear oil.
