just after some advice on gl4 oil for my is200's j160 gearbox

got recommended redline mt-90 but a few people have said it glazes the syncros?
what other oils would you guys recommend looking into?

can get 4L of MT-90 for $120

sorry if theres other threads like this already, im at work so don't have the time to search lol

cheers

Gearbox only needs 1.95L. Stick to the genuine recommended 70W90 GL3 viscosity and you cant go wrong :)

yeh i would but can get this redline for quite a cheap price
1l is 40 bucks so 4l for 120 is awesome lol
alot of people swear by it to

MT-90 wont glaze your synchro, that's why we recommend you use it. It's GL4. GL5 has the additives that can potentially damage them. http://www.redlineoil.com/product.aspx?pid=46&pcid=7

Other alternatives I've come across are Amsoil MTG & TRD 75w90

According to an oil expert I was chatting to in England GL4/5 is also alright to use. This is different to a straight GL5 oil. It is GL4 oil that meet GL5 pressure tests/specs without the additives. That would open your options up to a few more oils like Fuchs, Motul & Castrol. Just check what additives it has in it before using it.

I changed my gear-box oil a few months back to Redline MT-90. Definintely noticed the difference. Very pleased with the improved gear change :)

yeh went the redline
$132 bucks for 4l
might do my diff aswell as my gearbox

Hi, i just put valvoline 75W85 GL-4 in my tranny, will that cause any problems??
chur,

Guys
I am using Motul Gear FF-LSD Type 2
75W-90 GL5.

Any issue with using GL5 in our gearbox?

is it really bad for the gearbox?. I just noticed the gearbox whines it bit...

I just used ATF Fluid, was told its safe and I did notice shifts cold & hot are a little smoother compared to Castrol VMX.

yeh i got redline mt 90 GL4
will put it in when i do my clutch

Why did you put front wheel drive oil in your car? GL5 may eventually cause premature synchro wear.
Motul Gear 300 & MOTYLGEAR 75w90 are the only potentially suitable products in their range for the J160. See my previous post about using GL4/5. If you want to play it safe stick at a straight GL4 like Redline or Amsoil

I used NULON's 75W-85 GL4 and seems alright a lot better that what WAS is it (Not sure what was in it) Nothing special but it does the job! I also used the G70 Gearbox and diff treatment.

Im looking at doing my box oil shortly.
Anyone know how much work is involved? do i need to drop my box, or can i access the fill bung without removing anything?

Im not even gonna ask which is the best oil hahaha

there should be a tutorial on here somewhere of how to do it haydin

Take the filler plug out, take the draining plug out, drain the oil, put the drain plug back in then fill it up. Put the filler plug back in and your done. No need to take anything apart. Easy as piss. Haha! search for "Gearbox oil change" on the forum and theres pictures.

yeah basicly lol
when the new oil comes out of the fill hole you know its full :P
