Priorslee weren't as helpfull as i had hoped, claiming not to know anything about Texaco N402. So i contacted Texaco UK (Chevron), a helpfull bloke called Andy explained that nobody calls the oil N402, its known as ATF 402 and is supplied to suppliers in minimum batches of 20 litres. He is going to send me a list of UK suppliers and further information about the oil for the Club.
ATF 402 information here:

I hadn't made the link betweem N402 and ATF 402 prior to the conversation with the chap from Texaco.
