The engine is designed for a specific fuel. The compression ratio is higher, and requires premium gas for best performance.

20 cents more, for 10 gallons is $2. That's a deal breaker, given the better performance on premium?

I'm a bit confused by the original post as well as one of the reply / comments. They talk about the extra price of premium for 10 gallons. I read on a Crossfire for sale ad that the tank is 16 or 16.9 gallons. SO, shouldn't everyone's price difference be based on a full tank, and not a 10 gallon fill up?? Just saying...

Premium is well worth it if you are getting a premium automobile with premium performance. The 87 octane savings might buy you a coffee per tank or 10 bucks a month. My major concern is ethanol, not a few pennies at the pump. I hope you don't shut your car off at traffic lights to save a couple of pennies.
