Cobb Tuning only recommend one oil for any Subaru, trans, diff etc. Redline. Mainly a Group V basestock (PE) and a high quality additive package. If you think its expensive in NA it's double that here (Oz). Pays for itself in time though with reduced fuel consumption (up to 6%). And where did this syn oil isnt good for Subes come from? My Sube dealer offers syn for regular servicing and I checked with Subaru Australia who said "it all helps". "Just dont change from factory fill until 12,500kms at least".

Just dont put NS in your diff, its for transaxle only. The 2 to 3 shift with NS in my trans is like a hot knife through butter.

Appears brake pads are too soft or you are a 'brake rider'. Have you tried a harder brake pad?

Exactly. I can go 5th to 2md double de clutching and maintain same speed in OB and older Mazda turbo I use as a fuel/lube/additive/grease test vehicle. Took much practice but just comes naturally now. Stops crunching even in Mazda that has shot synchro's

A bottle of Auto-Rx usually fixes seal leaks as long as the seals arn't damaged. Use with dino and follow the new updated instructions on the RX site. Sludge and any contaminants will be cleaned as well. It has transformed my OB and Mazda turbo.

Why do you want dino in your diff and trans?

If g'box old and worn synchro's maybe 75W90NS too good. Excellent in mine and brilliant when say -6C. Very expensive here too.

dino= dead dinosaurs=non-synthetic. But then lets complicate it with Castrol and it's Group III 'synthetic' eg. Syntec which is hydrocracked from dino but they rip you off selling it at the same prices as real synthetics, eg Mobil 1, Amsoil, Redline etc. Any wonder Castrol are not well regarded by a lot of 'oil aware' people?

Trans requires GL5, MT90 is GL4, a big difference. Cobb Tuning shows 75W90NS and a picture of the bottle in oil section for Outback, WRX, Forester, Legacy. Better re-check me thinks. MT90 could be 'crunchy time' unless you are racing.

75W90NS g'box and do diif with 75W90. (not NS)

Mine 'ground' until I changed to RL75W90NS. Only had 65,000kms on it mainly highway which might have something to do with it. Maybe older g'boxes are less tolerant of a better quality oil?

setright you will really appreciate the 75W90NS cold weather shifting performance if you get some. The change over the OEM stuff is very noticeable. Straight 75W90 for the diff. Available from Lubricare International, Taby, Sweden 46-08-756-6596 according to RL's web site.

How do I get in or out of 'valet mode'? tks...s

Please present the facts that putting syn oil in a Sube "is a bad idea anyway"

I concur! Redline 75W90 for the diff (75W90NS for man trans). Up too 6% better fuel economy too and the PE (Group V) base stock handles heat better than anything. My dealer even asked why my trans shifted so good when I had it in for a mid-winter service.

I got a free clutch 6mths after warranty expired. Which other manufacturer looks after you like that?

We have 10W30, 0W40 and the main one 5W50 which is everywhere. No 15W50 for some unfathomable reason.

Trisyn was somewhat lacking in barrier lubrication. Supersyn UOA's are so much better across the board. Now contains moly which is good. About the best OTC syn around these days. You really can't go wrong with the current M1 but they are formulated at the low end of the 30W range which causes consumption problems in many vehicles. Why Mobil don't have a 5W40 M1 I dont understand. Many Sube owners use Delvac 1 (5W40) which as a fleet oil is CI-4 and SL rated. A very shear stable product.

New filter every 2500 is good. Also M1 Supersyn is a vastly superior oil to M1 Trisyn (it needed to be). M1 has about 80ppm moly in the blend now, about time IMO.

Which oil and viscosity?

Bob Jane T Marts the largest tyre chain in Australia. I hear others have it as well. Amazing to go for a long drive and you can still put your hand on the tyre after wheras if you tried that with air fill you'd burn your hand off almost!

A tip. Dont follow tha vehicle manufacturers advice re tyre pressures follow the tyre vendors advice whic is always very different. The vehicle manufactures pressure is to ensure a nice quiet ride and that buy tyres regularly and hopefully from the dealer network. I don't know anybody 'tyre savvy' that runs less than 36psi and most 38-40psi. Less flex = cooler rubber= longer life. Better handling a bonus. I personally have Nitrogen fill in my OB which is so much better again and not having to check pressures all the time (Nitrogen doesn't leak like air) alone makes it worthwhile for me.

Exactly. Till I found BITOG I wouldn't have touched Pennzoil even though it's everywhere here in Aussie just because of all the old wives tales. The new Pennzoil Quaker State base oil refinery was a joint efort with ConocoPhilips called Excel Paralubes that gave rise to the Purebase range, a whole new ball game. Conoco Hydroclear same stuff I believe. As part of Shells takeover of PQS a condition was that it's 50% share of Excel Paralubes had to be sold and Flint Hills Resources LP are the purchaser. Purebase is a Group II+ basestock, excellent additive package and now a healthy dose of moly. Hard to beat and excellent value for money. I currently use 5W30 version in my OB doing an after Auto-Rx rinse. FWIW It's the last time I will use an XW30 in any vehicle I own, the OB sounds like a tin can full of ball bearings, so back to XW40 soon.

Hello Toronto. Hope to get there one day, and catchup with some bitog folks 'in the flesh'. This forum is excelent fot those lucky enough to drive a Subaru IMO.

BITOG forum and FAQ's etc will teach you all you want to know about oil, filters both air & oil, greases. additives, engine internal cleaners, fuel system cleaners and much more such as which oil filters have the least pressure drop etc. No flaming and many contributing STLE"s, other highly qualified tribology experts and even Blackstone Analysis and Terry Dyson Analysis are contributors. Sure helped me get my Outback running far better and much better economy too. Also you will learn why Pennzoils new Purebase is generally regarded as one of the top three dino's in the industry (it's a Group II+ basestock) along with Delo 400 and Mobil Delvac 1300 Super. One of the main reasons Shell bought Pennzoil/Quaker State. Wax based it certainly isn't (it's parafinic) as are Conoco, Chevron, Havoline etc Group II+ basestock products but it's far too complicated to explain here, and requires somebody far more knowledgeable than I to do so correctly. http://WWW.BOBISTHEOILGUY.COM for more
