premium fuel required?
#3
Not sure if this would apply to the "modern" '97 model, I did an extensive test for a several months back when I was driving about 750 miles a week. On my '94 it turned out that the added cost for premium was almost made up in the increase in mpg. It came down to less than a dollar difference per tank when considering mpg. The car had much more pep on premium too, if the engine starts to ping, which I imagine on 10 to 1 compression ratio it will, the retarding of the spark to compensate reduces the gas mileage. One might argue that cold start ups are better on lower octane fuel though.
