I went to buy some Castrol transmax Z today, but have been told by a couple of places they can't order it in, and the only format you can buy it is in 20l barrels.....So i CAN however order in the entire Penrite range, anyone have any input on the best Penrite oil to use in my T5? REally wanted to use Transmax Z but that seems to be out of the question for us Kiwi's as Castrol NZ doesn't supply 4l bottles. I'm after top quality fully synthetic stuff that is as good if not better than transmax Z

Maybe a synthetic version of ATF DEX II or III.????

Have since found a replacement. Fully synthetic Castrol Syntrax. Looks tops.
