Switching to Royal Purple

[Nvdgtr]

actually come to think of it.. i have Redline MT90 in my tranny not shock proof lol.. not sure why i forgot.. but either way it works good for me.

[RixR32]

Diffs/Tranny - RP MaxGear 75w90
Transfer Case - RP MaxATF
Engine - RP 5w40, + Purple Ice additive in the coolant
Attessa - factory fluid. Not sure if any RP stuff is compatible and didn't want to mess with it.

Been working well.
Tranny has never had the 4th gear (or any) grind so can't comment if it fixes that temporarily or not.
May experiment with the Redline in the tranny next change just to see if there's much of a difference.

i dont have a gtr so this question might seem dumb. but whats the transfer case exactly? its a part or the transmission right? and it has its own fluids?

[MarusGTR]

^ Its basically a small automatic transmission that's controlled by the ATTESA and distributes front and rear power (torque) distribution (RWD to AWD up to 50kg/m IIRC)

Its located at the rear of the transmission, between the main drive shaft and the transmission.

Nissan calls for its ATF special fluid which is just a special blend of low-cold weight powersteering fluid. I use Motul ATF.

ATF fluid is just Dexron fluid. When car was made they used Dexron 3 fluid in powersteering (I think with additives to help with seal longevity), autotransmission (also probably transfer case on GTR). New, old cars should use the new Dexron 4 fluid -

Amnash, look at this videoclip, as it explains how 4wd works and how it's set for Group-A racing -

I run RP and GM EOS in everything, mostly because I have a whole bunch of it.

RP has done really well in some oil tests, and really badly in others. I'm not sure if it's good or not anymore.

the GM EOS additive is the only oil additive I swear by, mostly because in my first RB26 it made my valves SUPER quiet compared to running just straight RP. It's branded ACdelco and is available at any GM dealer in the parts section. Like $8 per bottle and I run half a bottle per oil change.

Ay, that's the ticket laddy. (said in my best Star Trek Scotty voice)
