Hi all I'm sure somewhere there will be a thread already with my answer but as your all usually nice enough too point me in the right direction here we go.. I'm going too buy some oil for my 03 blob sti gearbox and diff.
I probably wont get around too changing it yet as I still have a few things too do but as the moneys there I thought may as well buy it.
shes on 67k now so might have some wear.
I do drive it hard and I get a slight crunch (not a grind) going from 5th to 6th or back from 6th to 5th
And if its really warm and im giving her a hard time 4th to 5th but thats a rarity even if shes getting some stick..
Iv never had a problem with diffs aswell sooo any info much apriciated as always

 

Hi

You need a 75w-90 for the gearbox and diff .

If you want to go for the best, the Millers CRX 75w-90 NT, Gulf Competition, Motul Gear 300, Red Line 75w-90NS and Millers TRX are ideal for the gearbox. The Castrol Universal, Motul Motylgear and Fuchs Gear Syn are all decent alternatives. The Fuchs Syn 5, Millers CRX, Redline 75w-90 GL5, Motul Gear 300 and Gulf Competition are ideal for the diff. The Fuchs Sintopoid, Castrol Syntrax Longlife, Millers TRX, Motul Motylgear, Mobil SHC and Amsoil FGR are also good choices.

Cheers

does anybody know what size socket you need to undo the drain plug as I am about to do mine today. Its a square one nut unsure of what to look for as I am struggling to find one
cheers

 

Just done mine yesterday. 21 or 22mm socket fitted over it okay

If not a adjustable spanner should do the trick, need's a bit of a "Shock" to unseize it, should unbolt fine afterwards

AS for oil. I went with the Millers 75W90 Nanotech stuff, work's well. 4 litres in gearbox. 0.8 in rear diff

kept the 0.2 incase theres a little leak

 

Thanks tim the oilman I heard your the snet oil expert so I will take your word for it cheers

 

As I havent looked I am unsure if you mean a female fitting on sump nut..
A cheap set off ebay like this will be a good investment 161274430215

 

Thanks for the info

 

for my 2005 widetrack Sti with dccd is the LS millers better? can I use this in the gearbox and rear diff? so then I can get 5ltrs.

or what else can I use?

 

Hi

That is ideal for the diff, but for the gearbox, I'd go for this.
