I'm sorry. It's just that ten-page mega-threads on this subject barely fall off the front page before a new one starts. I take it you don't have a manual for your car.
I'll say 10w-40 fully-synthetic. 15w-40 will be ok too- ours is not a very cold country.
Be prepared for everyone else to have a different opinion.

Seriously, I'd forget asking on here...every man and his dog has their own differing opinion on what to use.
And of course, they are all oil experts too
Seeing you've been pointed to the ways of the search facility you'll see what I mean and end being more confused than before....sorry!

10W-40 is perfect
15W-50 is way too thick
CarLube are doing their TripleR Fully Synthetic at £12:99 ...........
But, you could pay 3 times that if you think it makes a difference ......
I would NOT put Mineral Oil in, or that reconstituted Motorway Oil ........
A lot of crap is talked about Oil, as you would expect from a Car Forum .......

Pete,
15w50 isnt too thick, if anything it will protect the engine better than the 10w40 rated oil as it keeps its stability better in hot engines like turbocharged scoobs plus its also the choice of STi, you know, those people who developed the STi with Subaru Japan

I will post, again, what Redline say:-
15W50
The ultimate high-temperature protection in Red Line engine oils recommended for street use. Good for engines that regularly run very high oil temperatures. Best for engines that run large clearances such as air-cooled engines or large-displacement, all-out racing engines that see occasional street use. Provides 25% more viscosity in bearings than petroleum 20W-50s. Not recommended for use in cold climates where temperatures are at or below 10°F or -12°C. Not recommended for street use in production engines that see sustained oil temperatures below 225°F (those engines should use Red Line 10W-30 or 10W-40).
I repeat this IMPORTANT piece:-
Not recommended for street use in production engines that see sustained oil temperatures below 225°F (those engines should use Red Line 10W-30 or 10W-40).

Yes, I have read what Redline say on their WEBSITE, but how do you know that that infomation is accurate? I know mobil 1's info is accurate due to the 20,000 miles that I have covered in my sti 4 (no remap) on mobil 1 motorsport 15w50.

Again, that doesn't tell us anymore than what shell, castrol, silkolene etc would say about their own products. ( They aren't going to run them down, are they?)
I cannot recommend any of the above companies simply because I havn't used them in an impreza. I have used Mobil 1 and have experienced no problems. ( 6 oil changes I believe in 20,000 miles. ) Surely Pete, if your impreza has been run on shell helix, and has suffered no engine problems in 60k, you should be recommending shell helix???

I see Shell are recommending grades of oils for cars now: http://www.shell.com/home/au-en/html/iwgen/shell_for_businesses/lube_match/app_lubematch.html
(albeit in Australia)

welloilbeefooked
does anyone out there still get their rides seviced at subaru?
what do they use when they do your doo?
they have been filling mine with mobil1 5W/40,
but i can only get it from them. it's £8.78 + vat for 1 litre
or you can take a bigger container and its £8.78 +vat per litre
(***!!!?), but it does need toppin up on a regular basis!
mobil1 recommend 10W/30 on their site, if you check that out,
but where i get mine serviced they reckon the word from
the boys in japan is to go with mobil1 5W/40. that seems like
a steady recommendation to me lads, but at the end of the day
the choice is all yours!
goodnight

In fact I do the same for the same reason, use Motul 5w40, and until now I can only be very positive.
