Hello Everyone, I come from forums Saab central& Saablink mainly US based) and everyone speaks highly of this site. My problem is because I'm talking to guys in the US, the brands they recommend are not avaliable in Australia (or are very hard to find and expensive). The main oil recommended is Rotella T6 5w40.Also 30 weight oil is to thin for our pumps at idile. A quick background on the car, My model (94-97 ng900)has been known to have a sludge promblem,but not as bad as the next model (98-03). I have recently changed the head gasket and found my engine to be in exellent condition. The run down, Car: 97 Saab 900 2.0 turbo(stage 3)270hp (approx) Specs:API service SG or CCMC G4 or G5 Australia Sydney NSW (Average Climate)never snows,Mainly warm Driving style: Spirited Daily Drive: 30 mins to work and 50 mins back (Traffic) Known promblems: Possible sludge Preference: Full Syn(40weight) at a reasonable price (like Rotella) Cheers Greg

With stage 3 turbo you may try 50 and 60 grade oils. Castrol,M1 and Eneos have good 50 grade oils. 10w-60 Castrol and Liqui Moly are easiest to get. But T6 is probably the cheapest one. Judging by Australian E-bay you have Motul availiable. But if you want to keep is safe and cheaper, I would hold on to T6 and change it every 8000km max. and use flush ones a year. Not sure about which variety of brands there, but sure that Liqui Moly is sold in AU(I have a can from Australia delivered), which work very good in most cases. Is gasket was changed out before turbo upgrade?

When I said Stage 3 I meant the ECU(computer) is tuned to stage 3. The turbo is a Garrett T-25,soon to be upgraded to T-28(300+hp. I think 50&60 grade oils way to thick.Its got to be 40 weight. The head gasket was after the last upgrade but I think it has always had a slight leak.Just as I have increased the hp the leak has been exposed more.

I like the sound of that.I like the thought of running a Diesel oil,knowing that diesel oil has better detergents to combat sludge.

My personal plan is just keep trying different oils, only because of curiosity(don't care about price(well not crazy like $200 for 5 liter racing oil)), and see which oil engine likes the most.

Thanks,Ive been on these sites before. I think GL lube is the only place in Australia that has Rotella.Gee its hard to get here and its such a good oil. I think I might just run Rotella in my car. I was hoping to find an oil I could buy anywhere and stick to it.

Isn't Rotella=Helix in Au? A Saabing friend is very happy with Liqui Moly. There is a well respected gent from Au on this board who was involved in applied tribology - his name escapes me at the moment, others will remind immediately. I would consult with him. Doug Hillary is his name. Sorry, my Alzheimer moment. And Mobil Delvac 1 is a grand oil, btw.

Mobil 1 0w40. Very high detergency for a gasoline engine oil, and has a long list of European manufacurer's approvals. If it's OK with Porsche for their turbo cars, it should be good enough for your Saab.

I was also thinking about the M1 0W40, but was not sure as to whether shearing resistance and HTHS is high enough for his application. Excellent oil.

I can get Helix quite easily but I thought Helix and rotella where different blends although being the same brand

all of the more experienced saab bloggers stay away from M1.They always say that M1 does'nt shear well. I have no understanding of this at all. What is shearing? I can get mobil products real easy

If I'm right, SAAB engine has low friction piston rings, so high temperature and high shear (HTHS) viscosity number is essential. M1 0W40 has 3.6 and approved by SAAB. Sometimes I use M1 5W50, it has 4.22, but no approval by GM/SAAB; the former owner always used this (BMW garage owner as well).

That's some good info. Most tuned up Saab owners stay away From M1, and I never understood why .You just explained it.Low Visco number. AAArrhh
