ARB airlocker diff oil?

[long stroke]

Hi all:)
I know there has been alot of discussion on this topic but i can't find out which is the best oil to run with ARB airlockers, LSD oil or 85/90 (standard).
So i thought i'd start a poll.

CHEERS TIM.

You wont need the LSD spec as it doesn't have clutchs in them..... well, they do have dogs if you want to call it a really really really course clutch.

I just run a Penrite hypoid gear oil... 85/90 from memory...

(and back in the UK I just used the same grade in an agricultural hypoid type gear oil - as we had big drums of it)

ps its not watt, its weight!

I just noticed that, for some reason i had watt in my head:angel:
Don't think i can edit a poll.

FWIW, ARB recommend a non LSD oil and this is the reason I was given.

According to an ARB engineer on another board LSD fluids may contain abrasive friction modifiers that will abrade the 'O' ring.
I called BS as no friction modifier I know of will do this and if they did, diff's would have failing pinion and axle seals all over the place, but he stuck to his guns... :rolleyes:

A blender I speak to confirmed what I thought.

My opinion, FWIW is that either would be fine.

Why would you use LSD oil in a diff that's NOT LSD, Regards Frank.

Because you can.
I just buy diff oil to suit the Patrol (80W-140 LSD) and so use it in the Sals too.
Saves having another drum of oil in the shed.

When I bought my airlocker (RR 10 spline) direct from ARB about 9 years ago, they stipulated that i should run limited slip diff oil to protect the o-rings and seals. The diff i bought was old stock and had been sitting on the shelf for over 2 years, the o-rings failed after about 2 months. When i went back to ARB, they said "what kind of oil have you been running in it?". When I said 'lsx90 just like you told me to' they said no problem, seals must have dried out on the shelf- rebuilt the diff as warranty job. That diff has been working without fault for 9 years/about 300,000km on lsx90, (except for when all the crown wheel bolts came loose last year:(- and I don't think that is oil-related).

When we took our front locker apart the other day all the crown wheel bolts were loose aswell:eek:
Thanks POD:)

Yep, that's the one :D

I couldn't be bothered digging it up Ben, thanks. Shows the memory isn't as bad as I've feared.
I'm still unaware of anyone using MoS2 as an LSD additive, but..... :confused:

Penrite Synthetic Gear Oil (costs about $30 per diff).
