Genuine Nissan oils

[RB_purr]

Hey guys

 

Has anyone had any experience using genuine Nissan oils more specifically for their gearbox I have been reading into it but I can't seem to find a great deal of info of them being used in older skylines they have it in 75-90 GL4 which suits my application but I want to know if it's actually worth getting and if it's any good

 

Or would it be worth getting redline MT-90

 

Anyone?

 

Cheers

I'd have to say, other than having seen the brand on an awesome race car I've seen and known nothing about them.  I have no idea what part of the market they are trying to cover between the basic oil makers / local oil makers and premium/overseas oil makers, or what the reason is that we would use them?

Yeah good point there has always been a lot of people boasting about redline shockproof oils etc etc but once again is it just personal preference or are these oils actually making any sort of difference

Redline Shockproof should never be anyone's first choice for tranny oil*. But it is the best choice for a bandaid for a box that has specific problems.

 

*I don't think this is like olive oil, where it is obtained by squeezing trannies.  I think it's more like baby oil, where the babies are not squeezed.

Hmm, depends which tranny you're squeezing?

After a fair bit of research taking OEM specs and 25 year improvement in technology this is what I put into my cars....

Some may argue this and that and the other but this is just my recommendation:

Oil	Nulon Full Synthetic 15W/50 or Penrite 10W/40 Plus 10.
Rear Differential Oil	Nulon SAE90 LSD Gear Oil
Gearbox Oil	Redline MT-90 Gearbox Oil
Front Differential Oil	Liqui Moly 85W-90 Hypoid GL5 Oil
Nissan Long Life Coolant	Nissan OEM Coolant
Transfer Case/Actuator Fluids	NISSAN MATIC D ATF

Cheeers,

Bob.

A genuine Nissan oil branded created in modern times was not conceived specifically with your 20 year old gearbox in mind. It's no more suited to your vehicle than it is a Mitsubishi or a Holden - just an oil with an additive package that Nissan approves for use in their vehicles. It's therefore no more special than any other quality 75w90 mineral oil suitable for your application. I find with Skyline gearboxes, mineral oils are king - the synchros don't seem to like synthetic as much - something about glazing them.

As for Redline shockproof - only use this in a racing application or when you're trying to get more life out of your already worn synchros. It's expensive and will offer you no real benefit over and above a mineral 75w90 in a perfectly healthy gearbox.

In the diff, if you're running a 1.5 or 2 way clutch LSD, then Penrite's LS 85w140 I've found to be the most street friendly, resulting is less clunks during low speed turns. If you want more bite in your diff once it's heated, then you can run a thinner oil like the 85w90 they tend to come with.

Engine oils - most RB20/25/26 will run just fine on a 10w40, even occasionally tracked. If tracking often or your engine has had a long and/or wearing life, you might want something thicker once it's heated, so 10w60 or 25w70 etc. My personal pick for the street cars is Penrite's ten tenths 10w40 full synthetic. RB25 feels very smooth with it and I change at intervals of about 7500-10,000km - engine still running strong at 200,000km+ (an obviously wound back odo too). As a rule of thumb...mineral oils in sports/performance cars should be swapped out at about 5,000km, semi synthetics can generally get 7-8,000, whilst a good full synthetic will allow you a 10,000km interval presuming it is not too filthy. If oil comes out black (but not burnt / broken down), this is a good thing! Oil's primary job is lubrication, secondarily cleaning the engine. If your oil comes out clear after even 1,000km then it's not cleaning anything out of the engine. Unless freshly built, RBs loooove to produce carbon build up.
