GTR General Maitnance- Can i get someh help

[lt247]

As some of you may have read Here I just recently bought my GTR, and i have a couple quick questions in regards to its general maintnance.

1) What are the part numbers for Spark Plugs and Oil filter?

2) What Oil do you guys recommend i use? I was looking over that Oil test/review. I was thinking the Royal Purple 10W40 or Racing 51.. Any other suggestions/ comments?

3) For other fluids, such as coolant, tranny fluid etc.. Any brand suggestions from anyone? or will anything do?

Oil, Coolant, Tranny fluid. Oil Filter, Spark Plug/ Spark Plug Wires
Is there anything else i should do?

thanks!

Oil filter i forget what one you use

Royal Purple is very good 10w30 is more then fine for your normal driveing and track use anything like 10w50.

Tranny fluid i would use Redline MT90,dont use Shock proof it will eat your syncros.


Just keep some money ready to put in to your car when something goes wrong,because it will.

spent a few days going through the GTR tech section, and a few FAQs. You'll find all the answers there as they all been asked a dozen times over. My suggestion would be to your belts & pulleys, and of course being a GTR your pump.
Good luck, and spent a couple extra bucks to get it done right if you need to.

Sorry but in the transfer case , like you said its need a automatic fluid Dexron 3 compatible ......its take the Royal Purple MAX ATF oil ....not the MAX GEAR !!!

Shock Proof does NOT eat your syncros!Talk about misinformation!It has been used for quite some time in GTR's.I used heavy duty shock proof recently in my transmission because I was starting to get a 4th gear crunch.Transmission crunchs no more.It is a little stiff when cold though.Nissan Motorsports reccomended redline Heavy Duty Shock Proof to Tyndango @ RBMotoring.I'm sure Nissan Motorsports no what they are doing. Lots of GTR's in the U.K. use it as well.

for fluid it depends... if you have the cash nothing available here in canada or the US is better spec'd than Motul. others can claim it but so far still Motul is the only 100% true synthetic made up of 100% esters...

all we can do is wait for Castrol or Shell to bring there true synth here...

[atmguy]

Please read the whole of what I have written before telling me off friends! :-)

From what I have read in the Oil review pdf file that can be found around here somewhere, Royal Purple outperforms pretty much anything put in it's path including Motul. Please don't take my word for it, read the following independant study.

Here is the direct link, I don't take credit for finding this report. Unfortunately I can't remember the original poster. (I had bookmarked the direct link)

http://www.animegame.com/cars/Oil%20Tests.pdf

About the shock-proof, no, it doesn't eat the synchros... BUT because Heavy duty shock-proof is just what the name implies (something along the lines of 90W250, the redline shock proof lightweight is 75W140) it applies a great amount of excessive strain on the tranny. You know how stiff the tranny is when cold with this stuff in there is... Why? It's because of the oil's weight, which you have most likely guessed I'm sure. It is difficult for the oil to "squeeze between the gear teeth, causing extra strain in the proccess. When you put this in a tired transmission it of course makes it feel much smoother since it's soooo thick. Shock proof is meant for old damaged trannies that grind ALOT, it's a band-aid until you can afford a new set of synchros/gears....

All this being said, I am writing this out of knowledge gained from reading as many "independant research reports" I can get my hands on, as well as feedback from my mechanic (whom races and builds 800whp race cars) and from general consensus with this community.

I like how they selectively didn't test 300V :-P

if you do a search here or on google there are several articles which explains the differences between royal purple and motul... they're not even in the same classification of synthetics, there are 6 classifications... and if you do your research Motul (300V) is a step above anything royal purple has on the market... note after reading the classifications below that Motul 300V is the only 100% ester based (not ester “added”) oil on the market in North America. (there are others, like Castrol and shell has one but they don’t sell it here, only in europe) but this is the point that separates Motul and enables it to have 0 shear meaning its impossible for it to break down… probably why several other manufacturers use motul as there relabeled performance brand like veruspeed :-P

There are six categories of base oils. These categories define the type of base stock the oil is formulated from. The categories are as follows. Note that the base oil group category is followed by the manufacturing method (in bold print) and then a description of the oil characteristics for each category.


Group I - Solvent Freezing: Group 1 base oils are the least refined of all the groups. They are usually a mix of different hydrocarbon chains with little or no uniformity. While some automotive oils on the market use Group I stocks, they are generally used in less demanding applications.

Group II - Hydro processing and Refining: Group II base oils are common in mineral based motor oils currently available on the market. They have fair to good performance in lubricating properties such as volatility, oxidative stability and flash/fire points. They have only fair performance in areas such as pour point, cold crank viscosity and extreme pressure wear.

Group – III Hydro processing and Refining: Group III base oils are subjected to the highest level of mineral oil refining of the base oil groups. Although they are not chemically engineered, they offer good performance in a wide range of attributes as well as good molecular uniformity and stability. They are commonly mixed with additives and marketed as synthetic or semi-synthetic products. Group III base oils have become more common in America in the last decade.

Group IV -Chemical Reactions: Group IV base oils are chemically engineered synthetic base stocks. Polyalphaolefins (PAO's) are a common example of a synthetic base stock. Synthetics, when combined with additives, offer excellent performance over a wide range of lubricating properties. They have very stable chemical compositions and highly uniform molecular chains. Group IV base oils are becoming more common in synthetic and synthetic-blend products for automotive and industrial applications.

Group V - As Indicated: Group V base oils are used primarily in the creation of oil additives. Esters and polyolesters are both common Group V base oils used in the formulation of oil additives. Group V oils are generally not used as base oils themselves, but add beneficial properties to other base oils.

Group VI - A new base stock group to include polinternalolefins (PIOs). New base stock read across rules have also been developed, which allow Group VI base stocks to be interchanged with Group IV base stocks.


(Note that the additives referred to in the Group V description are not aftermarket type oil additives. The additives referred to are used in the chemical engineering and blending of motor oils and other lubricating oils by the specific oil company that produces the finished product.)

Good stuff! What about what I had to say about the shockproof?

[Stinky_1]

spark plugs are the same as 91 honda civic DX. Check the book and find what fits your budget

Engine Oil

I use Mobil 5w ~ 30W I found this to be the most resiliant oil and engines runs much smoother whilst using it.

this might be a dumb question but why do you have 75W90 & 85W140. do you just mean choose between the 2 or mix them? also royal purple says there is no need for additives with there max gear oil, is that true or just to be on the safe side add some? and 1 more thing, wouldn't 10w40 be better than 5w30 for a turbo motor?
(just about to buy my 91 skyline GTR)

Do NOT add anything to Royal Purple differential oils. You don't mix different weight oils. I wasn't very clear there, I just copied the brand name from RP's site. You have a choice between the 2 weights. I'm pretty sure I used 75w90...

I also used 5w30 Royal Purple XPR because it is specifically formulated for turbo, supercharged and nitrous engines in imported cars. This is what their site says anyway...


Here is the info on the diff oil:

Max-Gear is recommended for use in truck, motor home / RV, and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid.

Max-Gear is an ultra-tough, high performance, GL-5 automotive gear oil designed to provide maximum protection to heavily loaded gears while maximizing power output throughout the drive train. It outperforms other GL-5 gear oils because it combines the highest quality synthetic oils with Royal Purple's proprietary Synslide additive technology.

Max-Gear makes gears run smoother, quieter, cooler and longer without overhauls.

All viscosities of Max-Gear are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.

Thanks for clearing that up. I kind figured that but thought I should make sure.
