Oil spec - B207R

[Steve McF]

I was looking through my service book, and read some of the service info, and it mentioned the oil grade for the 2.0T as being 0W-30. I thought it was supposed to be 5W-30, and that seems to be what the car has had at every service, apart from the very first service when it did have 0W-30.

So the question is, does it matter? I guess not as here we are 18 years on, 13 services and 110,000 miles down the line, and the car is still on the road

The NG spec is I think 0W 30, mine gets 5W 30 because that's what all the cars get, but IIRC it is an option anyway

The Saab workshop manual, albeit written years ago, is fairly broad in the viscosity requirements.

0w/30, 0w/40, 5w/30 & 5w/40 are all approved.  but the important bit is the Dexos2 spec.  The only engine in the 9-3 that has a more specific requirement is the TTiD diesel.

I found the best price for a 5l can was Bill Jones at Saabits.com.  It will be GM 5w/30.
