Complete tune up list

[Kirk]

Hey all, I have searched and searched for a complete tune up list and can't find one. I do realize that one persons choice of fluids might seriously contradict with the next persons, but can't we get a list of acceptable fluids, plugs, wire etc. that are usable for GTR's?

Thanks all.

[Marke]

The following fluid brands you can't go wrong with:

Royal Purple (except tranny fluid)
Amsoil
Motul (gear lube for trany is very good)
Redline (Shockproof for trany is very good)

Each of these companies will make fluid for all needs(except maybe rad fluid)

Engine: 5w40 (lots of debate on this, but its what I use)
Trans: 75w90 or higher
Front diff: 75w90
Rear diff: 75w90 LSD
Transfer: Dexron3 equivalent
Brakes: DOT3 or 4 if you race.
Coolant: 50/50 of the best you can get and add Redline Waterwetter(or is it Wetter water?)

Stick with oem coil packs. Some say spend more for Splitfire, but my mechanics says they have a habit of destroying spark plugs.

NGK platinum or iridium plugs.

Purolator Pure1 oil filters come highly recommended as well as Napa Gold.

Anyone else add to this?

[Kirk]

Thanks for the response. I am thinking of going with Amsoil through and through. Any idea what the equivalents for the trans, diffs and transfer case are? Also, unless I am totally wrong, but shouldn't I put an LSD additive in the front diff as well. I read that the front and rear are the same. No?

If your going amsoil, go 75w90 manual transmission and transaxle gearlube in the front/rear diff, and manual tranny. Series 2000 20w50 for engine oil. Put a bottle of AMSOIL Slip-Lock differential additive in only the rear diff. In the transfer case, get any synthetic dexron-3 automatic transmission fluid.

Marke,

How come you don't recommend Royal Purple tranny fluid? I put this into my tranny a while back and I haven't had any issues with it. :?:

[Marke]

Danno

After I put it in my trany started grinding like crazy. Even after it was warm.

You can put LSD in the front but you don't have to, as it is not LSD.(unless of course you have an after-market front diff)

Any idea what the equivalents for the trans, diffs and transfer case are?

All the oil companies I listed will make oils for these applications.

Redline makes a Diff oil that has LSD additive in it already.

[Kirk]

Ok, here's what I am looking at so far.

Transmission
Amsoil Manual Transmission and Transaxle Gear Lube

Front Differential
Amsoil Manual Transmission and Transaxle Gear Lube

Rear Differential
Amsoil Manual Transmission and Transaxle Gear Lube
Amsoil Slip Lock Differential Additive

Transfer Case
Synthetic Universal Automatic Transmission Fluid

Engine
Amsoil Engine Flush
Amsoil Series 2000 Synthetic 20W-50 Racing Oil
Amsoil Propylene Glycol Antifreeze and Engine Coolant


What year 350z do I buy an oil filter for?
Any particular brand of brake fluid?
Any other input on spark plugs?
I have 56k on the car, do I need to do coils yet? Should I do them just in case? Where do I get them from?

Oh, and what quantities?

[Marke]

Oil filter:15208-60U00( this filter maybe bigger than the one on your car but it still works) Nissan Part #

Fuel Filter: 16400-53J10

Engine oil: 4.5L
Trans: 4.1L
front diff: 1L
rear diff: 1.5L
transfer: 1.8L
Coolant: 9L

Check coils for cracking, other wise don't change them till they fail. They are not cheap.

Motul brake fluid is highly recommended.

[Kirk]

So, is 75w90 good for the diffs? Should I be using something else?

[japan_import]

75w90 all around, except Engine crankcase, and transfer case.

so 75w90 in front/rear diff, and manual tranny.

[Kirk]

Someone has mentioned to me that I shouldn't use 75w90 in the diffs, that I should use something heavier. Has anybody else heard that? Or thought that?

[japan_import]

What did he say to use, and why? 75w90 is what most heavy duty 3/4ton trucks use for gear oil. You'll be fine. Any heavier is just too heavy.

[Kirk]

he suggested to use heavier 80w90 or more.

So it's not that 75w90 won't work for this application then right? It should work just fine, but heaview might be better?

[japan_import]

There is basically no difference between 80w90 and 75w90. The first number is the weight the oil is at when it is cold. The second number is the weight the oil is at, once its at operating tempurature.
Both oils will be the same thickness/viscosity/weight once they are warm.
The 75 weight will protect your cases just as well as the 80 weight at start up. But since it's a BIT lighter, it will be easier on your cases. The main thing is, after a couple minutes of driving, they are both the exact same weight. If you want a heavier fluid, you will want to move up to a 80w140. Which is WAY too thick for any car differential.

IMO 75w90 will be the best weight for cases. and 20w50 or 5w40 for engine oil.

Always full syn...

[Kirk]

Just what I wanted to hear since I already bought the oil

Awesome info. Thanks for you help.
