Hay all

I was told by people on this forum that redline lightweight shockproof gear oil is a GL-5 i rang up redline themselves and i asked them can i use the shockproof gear oil in my magna cause i was told its a GL-5 and they said no its a GL-4 and 5. So i can use it in my car. Went down and got some and my god it feels so good its hard to expalin u cant even hear any noises from the gearbox anymore and the gears a silky smooth. Now i feel abit safer as its shock proof aswell and will help protect things from blowing up. Anyways i would recommnend this oil for anyone who drives there car harder then normal

sounds good, how much was it?
the problem with GL5 is that apparently it damages the syncros in our boxes.
if it is safe to use, i may put this in mine, as i do drive it pretty hard

Na this is a GL-4 oil. Its alot cost me $110 for 3 litres but its so worth it

Might want to check the bottle kurt as the info on the web I found seems to indicate lightweight shockproof is a GL5 oil. What does it say on the bottle?

Redline lightweight shockproof is gl-4 compliant. It is safe to use on our syncro's, I run it in my manual VR-4 legnum, and it has a much better feel than the other recomeded amsoil gl-4 oil.
I was dubious at first about it being a gl-5 oil, but had confirmation from a few sources (including Steve Knight) that it is AOK.

Ah ok, good to hear. GL5 no likey brass syncros.

Never tried the shockproof, alwyays heard the MT90 was a better oil.

How much for enough for a magna?

Youll only need 3 1litre bottles its expensive stuff but feels amazing in the box. Plus this could be a possible solution to not breaking your box as its got shockproof additives.

lol i wouldnt go that far, me thinks no thrashing it, will stop breaking the car lol

Shockproof = a name.

Oh, and stop putting ".?" in your thread titles, it's either a full stop or a question, not both.

ha ha people are so picky about grammer! lol

No, no, I'm picky about grammar.

ha ha lol, i misspelt it to see who would pick it up.

When you say 3 litres, does this mean its a supplement and not a full replacement?

Sorry pal

Kurt how much did you pay?

There ya go

the manual 'box takes about 2.7 litres, so I would say that it's a full replacement.

Ahh OK, I was under the impression that its for auto boxes.

Hehe cheers Timmy

Interesting, thanks Kurt :)
I too was under the impression Redline lightweight shockproof was a GL5 oil.

So far I've use Castrol Syntrans which is ok, and currently a mix of Redline MTL and MT90 which is better again.
I'll have to give the lightweight shockproof a go.

Ah ok, good to hear. GL5 no likey brass syncros.

I have found over my last 3 cars (r32 gts-t, gt forester and now vr4 legnum), I have tried the correct transmission oil ie mt90, mtg (amsoil) etc, but the shift feel was still not great. All 3 have ended up with shockproof lightweight, and it wins hands down.
There are reports that it 'goes off' after 20-30k, but I am yet to have to replace it (only done upto about 20k before changing said cars).

Definately my choice.

I get mine from www.peformancelub.com if you want to save a few $ (I am not associated with this guy, simply where I have found the cheapest prices over the past 3-4 years)

I have used the MT90 in my last 2 cars, and now in my fiances Ralliart Colt. Much smoother shifts, and it's the only oil I've tried that doesn't crunch on hard 1st->2nd gear changes in the Evo, and it also seems to prevent high RPM lockout. I haven't tried the lightweight shockproof, but I read enough about it on the Evo forums to give it a miss.

yeh i wouldnt touch the stuff

mt90 is what ive used and would use again

why do you evo guys not touch the stuff?

ill quote meek, a well respected evo workshop... this is their comments on redline shockproof

"I will take a photo next time that I see it. Inside a gearbox there are holes drilled in shafts and other components to allow an oil supply. Would you deliberately block these holes with a powdery paste? In the case of an EVO4-9 would you stuff your front diff with the same gunky crap? The centrifugal force of the high speed rotating components will cause the oil to separate the heavier particles. It seems the powder will then stay separate. I guess the powder is added to the oil as a cushioning medium. The claim is the such oil additives will "quieten noisy gears and bearings" It seems to be effective at that...but so is sawdust. Then you get the issue of sulfur content and soft metal reaction. Friction modifiers and syncro ring deterioration"

other workshops and people have said similar..theres been plenty of dead boxes after using shockproof

redline mt90 doesnt have this kind of issue and i find it very nice hence why id use this again.. but definitly not shockproof after the amount of evo boxes its killed

thats an interesting read there. granted evos are different (before mal jumps in on that lol)
but the same principles apply. when they mention deterioration of the syncros are they using a GL5 oil?
or perhaps the shockproof is not GL4 complient. you wouldnt expect such an expensive oil to ruin gearboxes like that.
how much is the MT90?

The MT90 is about the same price. $120 or so for 3.7L (1 US Gallon)

A Magna and Evo gearbox won't be completely different. The Evo 6 speed is the same as the Evo 5 speed with another gear in it (physically the same size box) And AFAIK, the Evo 5 speed isn't much different from the Magna 5 speeds. So it is applicable.

No, I actually agree 100% with Disciple here, the Magna and the Evo box are very close cousins and anyone putting an oil in a box with an additive like this stuff has is mad.

The additives will separate and block passages. the issue here is that manual boxes are spash feel, they do not have oil pumps which will pump oil at pressure and clear out these passages

Personally I love Nulon fluid, it allows smooth shifts, is the correct GL4 compiant oil and seems to stand up to most boxes I have used it in with it still being fairly clean when time for change has come along

Disciple, just out of curiosity, what do you use in the EVO Transfer case and rear diff.

well there you go, i may use the MT90 for the tranns, i agree Nulon is nice stuff, i use it in the engine, seams to keep the noisy tappets quiet, but they will be needing replacing soon anyway

how often should the manual gearbox oil be changed?

40,000 kms from memory

ok i should look into getting mine changed then thanks

The Evo 6 speed is the same as the Evo 5 speed with another gear in it (physically the same size box)

hey man, actually if youve seen a 5 & 6 speed side by side they look a fair bit different (obviously extremelly similar but definitly not the same casing)... and the e8 box is a HEAP heavier...

ie i can lift a e6 & magna 5 speed back into the car when doing a clutch change.. e8 box i couldnt.. really needed two ppl...

but i do agree.. magna and evo boxes are for very similar, for the purpose of this discussion.. the above is just some general observations ive made when pulling the boxes in and out of the cars in question...

mal FYI, i use Castrol SAF-XA in my transfer & rear diff.. its a SAE 80W-140, API GL5/6 ... used in both my e8 and e6

I wasn't aware they were that different. I was just passing on what I had read on the Evo forums. Good to know.

I use whatever Nick from Neal Lowe Motorsports uses in my transfer case and rear diff. I think it's Castrol Syntrax something or other.

how often should the manual gearbox oil be changed?

well looked it up, the service manual says 105,000 kms, but i think thats too long
and 45,000 kms under heavy operating conditions, such as taxi/police
the hayns manual says change it at 40,000kms

have had good results with vmx80

I just changed my Ralliart oil to VMX 80. Not sure what what in it beforehand. Shift feel worse sonI drained it after about 2000km and put in Castrol syntrans 75w85. It is made for better synchro performance and is recommended when VMX M or VMX 80 is is the normal fill, such as third generation magna boxes. So far much better feel and no 1st to 2nd crunches.

Not cheap at $33 per litre but a more readily available alternative to the Redline oils and from my understanding similar performance.
