Gearbox/diff Oils

[mystery_kid]

i know there is quite a few threads out there about this and i've read through a lot of them

i probably see redline mentioned the most and for every post for redline there is someone to post against it for whatever reason, as well as motul

i've just bought a gt-t, i've already done the engine oil and will be looking to do the g/box and diff soon.

i don't mind spending money for decent quality gear

is there really a problem with redline (seen a lot of people mention it's not for gearboxes with syncros)? though i've not seen that for sale at autobarn/supercheap here in brissy

same goes for motul?

or should i be just looking at castrol gear?

thanks

I used Redline. Gearbox has never been so smooth

Definitely recommend it.

shit wrong forum section

yeah that seems to be what a lot of people are saying

redline lightweight shock proof?

For what it's worth the gearbox is in really good condition the gears practically click into place, can be hardish to get into first and 2nd when cold though. No crunching

should i go redline mt90?

I run castrol syntax 75w85. No complaints.

Just re-did my gearbox and it's running smoother then ever with this oil. But I get it pretty cheap

Redline seems to be the answer to worn boxes. If yours is ok I would just use the fluids in the sticky above or Motul if you have a few extra dollars to spare.

I think the reason alot doubt on the redline is because it is made for racing not daily driving so there is no real need to put it in a street car..same goes for stuff like motul 300v chrono engine oil.its not designed for driving to the shops its designed to go round a track at 200+kmph so putting it in your daily is not only a waste of money it could potentially do more harm than good

so the question is what are you using the car for..

anyway there is a whole thread on driveline oils if you cant figure it out for yourself you havent read the thread properly and asking again here isn't going to give you a NEW answer because we have all read the same thread..

At the very start there is this

For a sticky.............................

What we use;

4WD Transfer = Castrol Transmax Z

Automatic Transmission = Castrol Transmax Z

Manual Transmission = Castrol Syntrans 75W-85 or Castrol Syntrax 75W-90

Differential = Castrol SAF-XA

this man races cars, I believe with some success so maybe he knows a little about oils..

However if you are thrashing the crap out of your car sideways well you may think you want a little extra protection so you could spend on the redline, just remember its designed for high powered racing if this isnt you its a waste of moeny.

So the question is, are you racing a high powered skyline or just driving a skyline?

we use castrol lsx-90 at work in lsd diffs, whould that be anygood in my gts4 diffs?

[mystery_kid]

yeah arthur, i completely forgot about this section of the forum when i posted this thread, i originally posted it in another section it was moved here by an admin

i've been through that thread and yeah i will go with castrol

it's a daily with maybe 3 or maximum 4 track days a year in it

dont get the vmx-80..

I did cause it was cheap but its junk, well its ok once it warms up, but it takes half an hour to warm up

Get a multigrade, Ill be getting the syntrans or even the penrite gear oil is ok too I think, it feels good in my diff anyway

[mystery_kid]

yeah i did the oil in my r32 gearbox with vmx-80 and tbh it felt worse after and i had no idea when it was changed before i did it
