Gearbox/Diff Oil....What's best??

[dragonheart]

Soon to be changing my gearbox and diff oil, was going to order this from mx5parts but after reading the review i am now in 2 minds. What do other owners use?? has anyone used this?? if so what results did you get??

Here is the link to the oil.

Does anyone have an opinion on this??

Would the same oils be used for the 5 speed?
