Hey guys i have done tons of searching and reading for hours on all this info here and other places but want to ask this question for my year car to get a better answer before i go get an oil change done.

I own a 2007 9-3 2.0T automatic.

Here in manitoba canada our weather gets ridiculous lol. a week straight it will be 35.C and then over night will be 5.C
In winter it gets to minus -35 no problem.

So my manual says mobile 0w40 and its hard to find out here.The local mechanic said i should never run that and its wrong LOL....

My question what oil should i run in the summer months. We put on 3000-5000km a month mostly highway with mix of city.

I bought a bunch of castrol EDGE 5w30 but now not thinking this will work on my car.

What can i run that will give me the best protection and the best fuel millage?

Oh, noooooooooooooooo. Another oil thread!!!

All SAAB GM manuals can be found here
http://www.extendedgmwarranty.com/owners-manual/saab_owner_manuals.html


Recommended oils are 0W-30 and 0W40. I'd stick with those. Full Syn always, Mobil 1 if possible.

Local mechanics can be great guys, and overall knowledgeable. But does he know SAABs?

from the 2007 manual

Engine oil​
To meet demands in Saab's extended service intervals all engines
are filled with specially designed synthetic factory fill oils.
Long service intervals, fuel economy and environmental issues
are the base for our choice of oil. By using oils approved by
Saab you minimise the tendencies for oil sludge build, by that
protecting the engine from harmful, wear increasing, deposits.​
Approved oils:​
For all gasoline engines - fully synthetic engine oil - approved
against the GM-LL-A025 specification - with viscosity SAE 0W-
30 or 0W-40. To benefit from Saab´s specified service intervals,
pleasure ensure to select a fully synthetic engine oil approved
against GM-LL-A025.
For optimum performence Saab recommends the use of Saab
Long Life Turbo Oil 0W-30 or Mobil 1 0W-40 European Car Formula,
but other fully synthetic oils approved against the above
specification and with proper SAE viscosity 0W-30 or 0W-40
may also be used.​
Servicing/Oil changes:​
To be able to use recommended service intervals the need to
use only approved engine oils is vital. Use only engine oils approved
for your engine. Service should be done according to
the recommended service intervals to optimize your engine's
function through out its entire life. Saab Automobile AB will not
take responsibility for any damage that might occur due to neglecting
to meet above mentioned requirements.
At your Saab dealers you can find Saab Genuine or Mobil engine
oils. Among those there are oils specially designed to meet
your engines specific needs. We recommend that you, with the
help of our skilled service personnel, choose your oil from that
selection.
Other oil companies also offer engine oils approved against GM
specifications. Oils meeting these standards may be marked as
synthetic. However, not all synthetic engine oils will meet your
engines specific requirements. Please ensure only to use fully
synthetic oils approved against your engines specific requirements,
i.e. GM-LL-A025 with viscosity SAE 0W-30 or SAE 0W-
40.​
Recommended oil viscosities.​
Viscosity is a measurement of the oil´s thickness at various
temperatures, according to the SAE standard. The thickness influences
e.g. fuel economy and cold starting properties. For optimum
performance Saab recommends:​
For gasoline engines:​
SAE 0W-30 or SAE 0W-40 engine oil.

Thank you for the reply.
Yes i read the manual before i posted this thread lol.
I was reading on here and someone stated saab changed the oil the recommend and not to use the 0w40 because it was spun bearings or something so that confused me haha...


So to confirm just 0w30 and 0w40 all year round full syn of course and as long as it says dexos2 or acea A3 then im fine correct

Good post Zin;ol;

In the winter a 0W weight would be preferable. Your Castrol Edge would be just fine year round though. The manual in MY 10 stated a 5W 30 or 5W 40 would be fine too.

If possible I'd use an oem oil filter as I'm a proponent of only using oem oil filters in any car. It's only a few $$ more and you always know you're getting the proper application. Others will disagree with me though which is fine too.

Yes, if 0W hard to get 5W would be OK, it is listed for later models. It's my belief that they recommend 0W for turbos to increase lubrication upon startup, and not just because of cold weather.

5w-40 and 5w-30 work perfectly as well

Well found a place that sells the 0w40 at 11.49 a liter and and quick lube place that has it including the filter and labor is 100$. So i guess it not much of a difference getting the lube shop to do it lol plus they will grease anything that needs greasing under car and top up of fluids
