Nissan were correct in advising of regular changes, as samples we took from our test vehicle at the 1800 mile mark showed that (under Filtergram testing conditions) fine particles of metal, some as big as 200 microns existed within the transmission. Laboratory testing proved the factory GR6 fluid to provide very little high temperature lubrication, allowing metal to metal contact on the gear faces, creating premature wear conditions, and giving limited 'cushion' to first gear when Launch Control is activated.

Blending and then testing a suitable high quality gear oil solution required a two pronged attack. Protecting the gears against wear and metal/metal contact was already well researched, but making this fluid then work correctly with the Borg Warner wet clutches and deliver factory feel through the driveline was the challenge. The perfect balance was achieved after extensive testing, with WR35TM delivering stock clutch feel, reduced gearbox noise, and lower operating temperatures. The best news though is that the wear rate of the gearbox was slowed over 150 times by reducing the metal/metal contact of the gears.
