Plan to carry out fluid change on all the wet stuff,what is the best to use
Looked for a service FAQ but could not find one?

Engine oil
Gearbox oil
Diff oil
Coolant (antifreeze)

Is it best to use main dealer stuff or other?

Cheers.

Depends on the mileage of the car and what has been used in it before, to a certain extent. A good quality 10/40 semi-synthetic at the very least in the engine and 75/90 in gearbox and final drive. Look to a make such as Millers (from ASPerformance or Opie Oils if you have nothing local)
Looks like a bugeye STi? Don't forget (if you didn't know already) that the gearbox/front diff has two drain plugs.

cam20

gixxerjoe

Cheers on the engine oil, found on here for the rear diff but does the gearbox share same oil as the front diff or is this separate?

Heard that there can be issues with some makes of diff and engine oil?
Found out that you can not buy the oil from the dealer?

mark1esc

try a company called witham oils mate they will put ya right on all the oils you need .

Is there a procedure for oil change on the gear box, IE when hot/warm or cold
And locations of the two drain plugs and where to fill back up is it via the dip stick?
Cheers

Did you find out the volumes of the diffs and gearbox?

Inviroman

iTrader: (2)

From what I can find is the gearbox is 4-4.5 litres and the rear diff about 1 litre.

Maz

iTrader: (34)

Gearbox is around 3.5 litres and the diff about a litre.

Inviroman

Take it that the front diff and gear box share the same oil?

Heard that there can be issues with some makes of diff and engine oil?

Engine...........4.5 ltrs
Gearbox/front diff (6 speed)...........4.1 ltrs
Rear diff..........0.8 ltrs (governed by the filler/level plug on level ground)


Gearbox/front diff drain plugs........main one below the front diff (you'll see it when you get under) second one is in a small sump, under the gearbox covered by a plastic shield. Re-fill via the dipstick tube.

All oils should be hot/warm when draining to allow good flow.
Punch a hole in the bottom of the oil filter and allow it to drain before unscrewing or you may get rather oily when it comes away!
Don't forget to pre-fill the new filter before fitting.

Thanks all for the support and assistance.
This is what I plan to order from Opie Oils, will get the fuel filter elsewhere.
Any comments?

Only comment I would have is the oil filter can be had for slightly less (genuine) on eBay , depends if your bothered or not.

JohnD

Arguably, the CFS NT engine oil is a bit of overkill. The non NT CFS is perfectly fine for your application.
As mentioned, there is no need for a 'genuine' Subaru filter. You can get an equally (or better!) filter for half that price - eg Blueprint.
The money you would save on the oil and filter would easily pay for the new fuel filter.

Yeah i also run BluePrint oil filters, however some people are picky about using OE parts

JohnD

iTrader: (5)

Whoops! I mis-read the list! The NT transmission oil will be fine (I use it in my 6-speed and it's excellent)
I do think the 10/60 engine oil is too heavy, especially as winter is coming on. If you engine's reasonably standard, use 10/40CFS

JohnD

The oil in the list is 10/50 not 60, may be the inserted screen shoot, but definitely 10/50

Inviroman

After a phone call to Opie Oils they advised Millers CFS 5/40
Any comments?
Got my engine oil box/diff oil for just under £100 from Opie Oils
Got air filter/oil filter/ fuel filter/sump washer/ NGK spark plugs from Graham Goode for £50
Going to be busy on Saturday!

I have just gone for 5w40 millers as its winters time and better cold protection, will swap back to 10w40 on next service for summer

petethemeat

iTrader: (6)

I use 5w/40, it will be fine.

You will have a fun day on saturday then, when i got my wrx i did all the fluids & plugs (inc coolant). Gave me a warm fuzzy feeling after

Inviroman

iTrader: (2)

All my parts arrived today and roll on tomorrow

Inviroman

iTrader: (2)

All done apart from the diff and box, the rain was playing games with me today.
The millers engine oil seems to be good stuff

petethemeat

iTrader: (6)

^ good stuff. The rear diff will be made easier with a big syringe or similar

Inviroman

iTrader: (2)

Would have done it if the the fill plug would come out! Not easy on the floor even with it jacked up on stands would not budge.
Trip to my pals workshop for this I think.
