Which Type Of Redline Oil To Use?

[Simmo1985]

I'm going to be changing my gearbox and diff oil this weekend and I've read really good things about Redline Shockproof.

What type do I want to get for my gearbox and diff? Heavy or Lightweight?

I got quoted $115 for a 3.8 litre bottle from "Performance Wholesale" at Slacks Creek (Brisbane). Does this sound right? Will this be all I need? I read somewhere that the gearbox takes 2.4 litres and the diff takes 1.4 so it should work out ok. Can anyone confirm?

After much reading I'm going to go for the Motul 300. Thanks anyway.

I was told that shockproof will make the LSD shudder a bit. I used lightweight shockproof in the front (open) diff and gearbox, and redline 75-90 in the rear diff. Just make sure that whatever you get for the rear diff is LSD friendly. Also, you should use a GL-4 in the gearbox and a GL-5 in the diffs.

what do you guys recommend for a Cusco 2way? and shock proof for the gearbox.? light or heavy? the 2nd and 3rd are a bit crunchy when cold..

Lightweight shockproof is often recommended for tired R32/R33 gearboxes. Dunno about the diff - ask Redline for a recommendation here

i recently put redline heavy duty shock proof (i think thats what its called) in my gearbox. i havent felt any shudders so to speak but it is a little bit more difficult to shift into gear. espcially 1st when it is cold.

is this normal? my mechanic said this was the best stuff around.

i use ls140 with ford motorsport additive in my kaaz 2way so i dont see why it wouldnt work in a cusco. as for gearbox i use 75/90. dont see the point in using expensive shit when i'll only change it in 30,000kms

[MrStabby]

dont see the point in using expensive shit when i'll only change it in 30,000kms

The point is;

- You'll be better protected during those 30,00kms (and beyond)

- You dont have to change it until you get to 100,000kms

No its shouldnt be more difficult to shift. The common recommendation is lightweight shockproof, not heavy. Perhaps that's the problem.

Shudders would only occur in LSD diffs, not gearboxes.

Sorry i didnt get the shudder and diff connection

yeh well it definitly is alot harder to push the gearstick into gear. but like u say it is probably because its a more viscous oil.

other than that it is alot smoother since i changed the oil.
