Gearbox oil - Castrol TAF-X 75W-90 or equivalent
Does anyone want some tranny oil brought to CC? Opie say that the recommended oil (Castrol TAF-X 75w-90) "…is sadly discontinued so its while stocks last with this one." Specky x4 and I x4 need some and postage is free for orders over £100 so one more. The best I've found elsewhere is £12.99 per litre incl. P&P and Opie is £11.33 for members. The Elan needs 1.8l so 2 off to refill the box.

You learn something every day (just also done a search through the owners handbook and workshop manual and had a slight panic!)
