anybody else have a Saab 9-3 2.0t?  I have the 2003 Linear model.  I have been putting mid-grade in since thats what the used car dealer said the previous owner was using.  I have had the car for 2.5 years now.. I was talking to someone recently and they said that there is no need to put in a higher octane fuel. Even though it has a turbo is still doesn't matter. Anybody real car savy and know? What do you guys do? In NY 87 octane will be around $3.69 and midgrade(89 or 91) can be upwards of 4 bucks, sometimes $4.19.
 So 30cents a gallon, 4-5 bucks extra every full tank adds up.
