Sorry that I missed the bit about the diff, I have a lot of emails and forums to deal with, so I guess I was rushing. The Gear 300 is for the gearbox, the best option for the diff is a synthetic 75w-90, like the Silkolene Syn 5, Millers CRX NT LS, Motul Gear 300LS, Red Line 75w-90 GL5 or Gulf Competition LS. A SAE90 or 80w-90 mineral oil such as Shell TS90, Motul 90PA, Fuchs Race Gear 90LS or Gulf Gear LS 80w-90 is a good, cheaper alternative.

New owner
Hi all
I'm the proud new owner of an 06 STI Type Uk DCCD Widetrack PPP.
The car needs a service but there seems to be so much going on in the drivetrain that I don't know what I need to service it! It hasn't been serviced for 18 months (its only done about 3k miles in that time). The timing belt was done at that last service.
So I'm going to buy 5 litres of 5w40 fully synthetic and an oil filter.
Air filter (I'm planning on improving the breathing in the near future, is there an induction kit/cold air intake I should upgrade to now?)
Do I need a fuel filter?
Which spark plugs should I use for normal (town/motorway) driving with occasional fast road use at the weekends?
So I need 4l of the gearbox oil mentioned above (I assume its the same as the 05 model?)
1 litre of the rear diff oil mentioned above (again I assume its the same as the 05).
Surely I need some oil for the centre diff as well? If so what and how much?
Also I've read a little bit about a front diff? Is there a front lsd or is it just open and not requiring and maintenance?
Anything else I should be doing?
Also can I do all of this myself or best handing it over to my local independant specialist? I have pretty basic knowledge and experience of oil/filter changes and assume the spark plugs would be the most difficult bit?
I know there's a lot in there, gives you an idea of how confused I am!
Thanks in advance

Welcome, Call Alyn @ AS performance first class advice, massive stock and very competetive pricing. Its good practice to prime the oil filter and get the oil pressure up before starting the car after an oil change.

Although not based on personal experience, I've heard specialists recommend 10w 40 over the 5w. Impreza engines don't like going too thin on the cold weight. Spark plug wise I've always used ngk pfr7b but on a standard car pfr6b will be fine.
Gearbox oil I've always used Millers CRX 75w 90 nano tech. For the diff you'll need the LS oil in the same spec.
As above Alyn is your man, very helpful, good prices and a fount of knowledge.

You should be able to do most of it yourself, if you competant with a socket set, and have a decent one with an array of extentions for doing the plugs. They aren't hard to swap, just a bit of a pig of a job.
Gearbox oil is filled from dipstick, the gearbox has it's own dipstick. Located near the turbo. Rear diff is filled from the drain hole IIRC.
ETA, give Alyn a ring, 0191 410 3770. He'll advise better than me.

Thanks for the replies guys.
Maz any idea why the Impreza doesn't like the 5w engine oil? I thought the idea is that it gets out of the sump to where it is needed quicker and a thin layer of oil is better than nothing?
It does sound like I could do it myself but I've done plugs on a 350Z before and, quite frankly I'm far too lazy to do that again! I'll take it to the garage

Since I asked the question I think I better pop back in
Alyn supplied me with these oils,great service, easy to order and he's very happy to explain why he supplies this particular oil in this case.
Suplliers like him and his company make it a joy to own an Impreza.

not quite correct @Dubzy but near enough - its more the lesser of 2x evils.......
in general terms you would always run an LSD with LS additive and a synchro gear set without BUT when they share a common lubricant then you have to err on the side that causes less issues........LS additive can cause drag and wear on synchro's and upset the gear change, the downside is it has an LSD also is a potential for slightly increased plate wear

Alyn,
Might a blend of one brand of oil (eg. Millers CRX NT), one with LS additive and one without be a compromise (mixing 50/50 Millers CRX NT & CRX NT LS) or is it the old saying "never mix your synthetics"?

no because you are still potentially causing a synchro issue...........
we do (and have done this for years) on rally / race cars particuarly FWD stuff with upgraded diffs and its just something you put up with........
however this is one of the reasons you need to use a good quality gear oil so it withstands any heat build up
