Engine fluid quantities?

Will 10w30 be too thin??

[qualthar]

Nope, I was told by my mechanic (came here from Japan 5 yrs ago) to use 10W30 for regular driving, and 10W40 for track or racing.

I'm using 10W30 right now.

[rickskylinebnr32gtrjp]

I use 20W60 normally or 20W50 if I can't find or obtain the 60 weight.

It never gets colder than 45 degrees Fahrenheit here in Okinawa. During the 3 summer months it is 90+ degrees F with 90% humidity as well. A natural steam sauna for sure!

RB20 tranny: 2.7L is this correct? can anyone verify ? thanks

I used Motul Gear 300 75W90

[supermanskye]

anyone know what filter the rb20 takes ?

[klys]

240sx 1990

[delphir32]

i'm using
nissan oil filter #15208-55Y00
or
K&N #HP-2008

A oil filter that will fit th KA motors in nissans will work also ie, 240's and small p/u trucks.

I'm using some weird one from Nissan... 53J00 I think... It says RB26DETT right on the box.

Part number doesn't cross-reference through parts master though (Japanese one).

I'll double check in a bit.

ok going to correct some stuff here as I just replaced all my fluids...

Tranny GL-4 Motul Motyl Gear Technosynthčse 75W90 3.8L
Front Diff Motul Motyl GL-5 Gear Technosynthčse 75W90 fill to hole (1-1.5L)
Rear Diff Motul 90 PA fill to hole (1-1.5L)
Transfer Case Motul Dexron III 2.8L
Motor Oil Motul 8100 5w40 (in the owners manual 5w-30 is the suggested oil but since its slightly modified the slightly heavier oil is used)

8100 is good for everyday driving however if you want to free up a couple extra horsepower use 300V as the friction loss reduction is greatly reduced I've witnessed independent tests first hand were 300V has freed up 5-7% more HP than mobil one and castrol "synthetic"... the 300V that you buy is the same exact oil used in the JGTC cars, they get the same can as you do :P, its just a little pricey but if you use it you can definitely tell the difference...

as for the reason why there is an additive in the Rear Diff, its because the front is an open diff where as the rear is not I believe...

The Tranny is not 4.1L, as i did this and it over flowed my tranny once i started driving (and you will have tranny oil spewing everywhere when you do your test drive :P)... from what we can see i think this is meant to be 4.1 quarts which is about 3.8L's :P

LOL this was a huge scare as i though i had some major leak in the tranny :P

anyways thats all past now and the car is running awesome hope this info helps people

[klys]

will you rear diff oil work for a mechanical LSD?(2 way) I guess it should but I've change the tranny oil but not rear diff..

[nightlight]

Shouldn't this thread be stickied in the GTR tech forum instead of the GTS tech forum? Correct me if I am wrong, but I didn't think that the GTS' had transfer cases or front differentials to worry about.

[Maverick]

I know I am digging up old thread but as long as it is useful.

Anyway, I have a GTS-4. So should I be using the quantity of what Neal has mentioned? ~~ I think I do have transfer case and front diff right???ops:

how do i top up the transmission and is the transmission seperate from the gearbox?
all i know is when i took the driveshaft off i had gear oil coming out so i was wondering if it is a standard if it still needs transmission fluid, yeah stupid question :hit_head:

[BlackPearl-gts]

is it safe to run generic power steering fluid??

[M13]

is it safe to run generic power steering fluid??

Yes. I've used Gunk and it's been fine.
