I would use either Redline 75w90/80w140 gear oil or Castrol SAF-XA or Castrol LSX 90/140, or maybe even Royal Purple 75w90 gear oil (Max-Gear i think it's called). can find the redline and royal purple oils cheap @ www.performancelub.com

or really anything that meets GL-5 specs and is LSD compatible (80w90 is specified, though thats japanese conditions, I think 80w140 is much better for our conditions) and possibly compatible with Hypoid diffs (I'm not sure what diff R34 GT-Ts have)

Rear diffs are usually no more than 1.8l

Also note if its an A-LSD or a mechanical type :P

The use of the car(ie daily driving/track bashing/drag meets)

The climate your in as well

All these can factor in what oil will be 'Best' suited to your needs as different driving scenario's and so on all present thier own unique hazards. As a future reference you can pay a quick visit to www.castrol.com for a basic guide to your cars needs on oils for everyday operation :(

Enjoy!

As always, different driving scenario's require different approaches. It was posted as a basic guide for everyday driving and is the same guide 90% of our nissan workshops go by :)

On a personal note i use Mobil1 or Fuchs in the engine where possible and use Genuine oils in the driveline. (please note: Genuine Driveline oils from nissan are notoriously dear, MaticD for instance is scary!!)

As for Castrol's recomendation, its much the same with Mobil's, Penrite's, Fuch's and GW's oil recomendations, surely they cant all be wrong. Hope you get your oils sorted and good luck with your Skizza!

  • 1 month later...

I've ended up useing :--

Diff--Castrol SAF XE.

About 1.6ltr to fill it was a ass to get in due to a fat exhaust and it just didn't want to fill, I rotated a back wheel and moved the diff core waited a minute then it seemed to fill more easily.

Gearbox--Nulon 75w-85 fully synthetic smooth shift,

Don't whatever you do make the mistake of putting a hypoid gear oil of any type in the gearbox-ah hem --who me ? ;) - the shift will go to lead.The fill was 3.8ltrs

Castrol also do a Syntrans 75-90 which is suposed to be good as well and it's suposed to rrp at around $22.00 a litre but you will find that our enterprising :D aftermarket assholes often , if they have it attall , price it the same as Syntrax at around $33-35.00ltr.

The Syntrans is recomended by Castrol for the R34GTT the Syntrax isn't. (in mineral Castrol also recomend a 75W-85 VMX and a VMX-M 80 wieght.

I change the gearbox and diff oil every twelve months as I do most of my K's in small trips , I live in a hotish climate and I do low overall K's , I just figure its cheap insurance.

you mean castrol SAF-XA right ? Cant find an XE anywhere.. 've already got shockproof lightweight for the gearbox

Oh and I just read in another thread (http://www.skylinesaustralia.com/forums/Castrol-Diff-Oil-t157915.html) that the SAF-XA is too heavy for a skyline diff and to use that hypoid stuff ? Hmm ..might just ask Nissan what they use/recommend and stick with that for the diff.

Yup SAF-XA -not XE- typo , my bad.

OK. Heres a link to Castrols recomendations for R34GTT http://www.datateck.com.au/lube/castr_au/default.asp

And some more home grown advice here http://www.skylinesaustralia.com/forums/Transmission-

Lubricants-t205993.html://http://www.skylinesaustralia.com/fo...ts-t205993.html

And HHHmmmm hope you have more luck with your local pissant dealer than I had with mine who couldn't /wouldn't sell me or tell me SFA about anything to do with R34 fluids-of any type.

The Penrite 75w-90 SIN actualy came as a recomendation from a genius at Penrite.(no mention of friken hypoid.)

And :-

Product Description

Castrol SAF-XA is a fully synthetic rear axle fluid incorporating Castrol’s

most advanced transmission fluid technology. It is designed to provide

protection at the utmost extremes of very low and high operating

temperatures where mineral gear oils prove unsatisfactory. It is

Castrol’s prime recommendation for competition, severe duty and long

drain applications.

Product Application

Castrol SAF-XA is recommended for rear axles of passenger cars and

commercial vehicles.

Holden V8 rear axles.

Trucks including “road-trains” operating in severe service where

high oil temperatures in the differentials and power dividers are

encountered.

Competition vehicle rear axles, Group A, sport sedans, Formula

Holden, Rally cars. Castrol SAF-XA was the transmission-rear axle

fluid used by Sauber-Mercedes who won the 1989 Le Mans 24

Hour Endurance Sports Car Race and the 1989 and 1990 World

Sports Car Championships.

Both limited slip and non-limited slip rear axles.

For vehicles towing caravans and heavy trailers.

In certain manual transmissions, where GL5 80W/90, 90 or

85W/140 are recommended.

Covers full rear axle viscosity range from SAE 75W through to SAE

140.

“Legs” of outboard and stern-drives used in competition (e.g.

Formula One and ski racing).

Eaton, Rockwell or Dana axles where synthetic oils are specified for long drain

So instead of snide remarks I suggest you get of your ass and find out from your obviously compliant Nissan dealer then post it up for everyones information.

:whistling:

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
