I have the same car and get about the same mileage. I do get about 22 mpg at 70-80 mph on the interstates.
By the way, I read somewhere that the 84 500 only required 87 octane. I keep very good records of fuel consumpsion. I switched to 87 oct Shell from 93 shell and can' t tell a bit if difference. Mileage is about the same and the car runs about the same if not better.
Now I must say, I have ALWAYS used and recommended Preimun fuels, but with the price of gas now, I had to do something.
