Amount of diff oil

[Guest]

Does any one know how much diff oil is needed for a 2000 gt legacy station wagon, 2ltr manual? will be completely empty as is being converted from auto at the mo, Thanx

[dubbedup]

is it for the gearbox or the diff?

[driftrex]

4litres in gearbox, 0.8 litres in rear diff

[RS.YES]

Sorry for the intrusion (gtlegacy00) but seeing as I'm wanting to do the same service for transmission/gearbox & diff thought I might pop another question. What fluid should I use for a 1991 Subaru Legacy RS? and also for rear diff where would I find the bleed & fill valve/bolt? Probably bleed valve on bottom and fill valve on the side of the housing...am I right?? Sorry guys just don't wanna fork out alot of money for a mechanic when I can actually do it myself, cheers.

im a bit of an oil specialist so i'll answer this one too.

the factory spec oil you want to use for your legacy is a fully synthetic GL-5 rated 75w90, in both manual gearbox and rear diff, it will take the same quantities i have listed above.

drain and fill plugs for rear diff are on the rear cover of the diff housing, once you get under you will see exactly what i mean.

drain for the gearbox is at the front of the gearbox pointing down towards the road (22mm bolt), and the way you fill it is through the gearbox dipstick tube which is on drivers side beside where your turbo sits, take your time pouring the oil down the tube as it will easily overflow if your going to fast.

hope that helps you mate.

Just reviving this thread to ask if an r180 takes more oil than an r160? If I get 5L of oil for transmission and rear diff would it be enough? Car is v3 STI RA.

[funkytown]

rear diffs take 1quart = ~0.95L

cant remember what a 5MT takes, but 5l sounds a fraction low for GB + diff

[evljat]

Ok, cool. Also, is there any particular oil to use? I\'ve just been told use a full synthetic 75w-90 and stay away from Redline oil.

[Guest]

Think trans is 4l.

try this site. it gives all info of recommended oil and capacity for any vehicle.

double click on workshop lube guide under toolkit.

[loganrasti]

What\'s the issue with redline? Why do people say stay away from it?

[funkytown]

Its fine in 5mts and rear diffs (lsd type dependant) but cronically bad for 6mts as they have an internal oil pump and it ruins them.

[Roo]

Does "it\'s fine" mean it\'s not worth the extra money? I need to get some this week too and was thinking i\'d just go for what the garage would put in?

They all reference the same main site so will get the same results across agip/castrol/Q8/gulf western/etc.

It feels like slime dude whereas oil feels well like oil lol. Id run it if it didnt cost as much as my grocery bill. The repco/penrite 75W90 full syn will set me back 50odd for 5L so thats me next time I think. See how stuff I sell stacks up but should be cheaper.

[funkytown]

Its good stuff but for a road car your probably not going to notice any difference honestly. Or even a weekend beater.

Thats assuming the mechaics using the correct fluid for a subaru box..

[Roo]

Was the subaru specialists so I assume it\'d be as per what\'s listed?

Cheers will just get the normal stuff

[Guest]

If its roo its hardly standard road conditions lolol.

[Kiwi_Fozze]

so if i read correctly, 6mt, 4 litres of GL5 75w90 will be fine? have a bottle of valvoline stuff kicking around, should be all good?

sorry for thread hijack
