I know this one has probably been beaten to death and I realize everybody has their own opinion about what is best or more economical. I don't have a point of view on this issue because I know little about it. I have been using 91 (best you can get in California) for fear of hurting the engine. But this usually ends up costing me about $1.80-1.90 a gallon. I don't mind springing to synthetic oil or ATF. But premium over the next 100000 miles will cost me an extra $1000.
I would like to get a comprehensive survey of other 960 drivers and the experiences you have had with different grades of gas. Power, mileage, any strange noises or failures directly related to gas quality. Does the air temperature affect octane requirement?
Thanks for you imput.
Justin
