[9-5 Driver]

Help!!
I want to be protected by my warrenty and make my engine last long time w/ no sludge. I have had dealer change oil during the free service period, and i change it in between so that it gets done every 5000miles. Now that my dealer can no longer get the Saab brand turbo oil, what should I use.
I have called 2 different Saab dealers and gotten 2 different answers as to what brand/type/viscosity oil to use.
One told me to use 5w30 Mobil 7500 synthetic blend.
The other one told me to use Mobil 1 fully synthetic, and can use either 0w40 or 5w30.
What gives?
I have an 02 9-5 linear 2.3t.

Well hiya and welcome

Ok the spec of the Saab oil was:

4 Litres Saab High performance Turbo oil

4 Litres of fully synthetic multigrade oil. SAE 0W-30.

And most of use agree that Mobil 1 is excellent so the Mobil 1 0w-40 should be equally as good if not better than the Saab oil.

I have also heard great things about Amsoil, except we cant get it over here

Oil changes at 5-6000 miles is very good practice too

Mobils site says so too http://www.mobil1.com/USA-English/MotorOil/Home/Homepage.aspx

I would go for the mobil 1 0-40W.

I use mobil 1 5-50W in my car here in australia. Have got 0-40W here but can only find it in mobil petrol stations and in 1litre bottles only and more $$$.

I've just had the engine oil in my 9-5 changed by a non-dealer SAAB specialist and they used Mobil 1 5W-50

 

[Shiston]

Lovely stuff that mobil 1, feed it to my car about 2 weeks ago, shame we can't drink it :cheesy:

I thought the manual on my 99 9-5SE (V6 3.0) said 10W-30 or 10W-40. I use mobil 1 full synthetic 10W-30. Is this wrong?

 

[PeterGibons]

Another vote for Mobile 1 0w 40. After I baught my 9-5 I took it to the dealer and had the oil changed using Mobile 1 0w 40. Mobile also has a full sythetic transmission fluid that's good to.

Ditto the others, I've also settled on Mobil 1 0w40, but in the past I've used Castrol RS 0w40 and Silkolene Pro-S 10w50 - all seemed to work without problem. Shell Helix Ultra 5w40 also claims to be Saab approved IIRC.

 

[Raven18940]

I have yet to see 0W-40 anywhere, so I use 0W-30. I'd only use a 0W-something, no reason not to this day and age.

 

[AeroTom]

I have a 2003 Aero, should I use Mobil 1 0-40w or the 5-40w?? I live in Florida so no need to worry about super freezing temps. Wouldn't the 5-40w offer better heat protection? I will change my oil every 6k and also use a Mobil 1 oil filter as well.

 

[Raven18940]

Ok, small lesson on what the numbers mean. The W in 5W-30 means "winter" not "weight" like a lot of people think. 5W-30 means it's a 5 weight oil when cold and the 30 weight oil when hot.

I'd opt for 0W-40 because it'll offer better lubrication during a cold start (cold being relative to the engine you silly Florida people ) and they'll both be the same once things are fully heated up. And the 0W will offer slightly improved gas mileage as well.

 

[AeroTom]

Another thing to keep in mind that I have learned with oil for example is a 0-40w versus a 10-40w, the first one has a 40 point spread and the second only a 30 point spread. It is known that the farther theses 2 numbers are apart the quicker the oil breaks down. I know these hot turbos need the higher heat of atleast a 40w oil or I would go with a 5-30w since its a more stable oil and only a 25 point difference.

I am really leaning more towards either a 5-40w or even a 10-40w since it doesn't get that cold here in Florida. What does everyone think, I really want to be able to put 200k-300k miles on my Aero?

 

[Raven18940]

If it was normal oil I'd agree with you, but this is Mobil 1 fully synthetic. This stuff just doesn't break down, it's rather amazing the temperatures and conditions it can withstand. Also you're changing it every 5000 miles, which by modern standards is pretty often. In the end it's your car and your decision.

 

[Kermit]

I'd agree with Raven here, as far as oil goes you get what you pay for, Mobil 1 ain't cheap but boy does it live up to its reputation. It takes a bit more than a turbo and 250bhp to break Mobil 1 down, thats why its so widely used in all motorsport applications, F1, WRC etc. :cheesy:

Hi AeroTom - it's good to take a keen interest in the ins and outs of what goes in your car, but to worry yourself about the difference between a 0w and 5w is splitting hairs in my view. Personally, I'd use either, interchangeably, without even thinking about it. If you need to maintain a Saab warranty then go with the handbook spec oil, otherwise, any top brand synthetic will do. Mobil 1 is approved for Mercedes-Benz, AMG, Porsche, and Shell Helix is approved by Ferrari, while Silkolene Pro-S is a favourite among the Impreza turbo crowd, so any of these is likely to be more than adequate for a Saab. Buy the one you like the look of the most and then go and enjoy your car, giving it plenty of welly! :cheesy:

everyone has suggested that mobil 1 0w-40 is the best so far for these Saab engines. but what if you lived in the north, aka Boston? Should i request for mobil 1 0-40w?
since, with the help of Raven =)

what happens in the dead of winter? would the engine turn over?

(please note, im a newb with this. just got the car last week, trying to follow the best procedures to make sure my car will last me. and feel free to laugh =) )

oh and one thing too.
when i get my oil changed, do i request mobil 1 0w-40? or do i have to bring it in when i bring in my car for an oil change. and how much does it cost?

thanks guys
