LOL never complain about gas prices to a Canadian. We are at around $4.50 a gallon for regular right now. Premium is going to run about $5.10 to $5.30. The sad part is that this is about as cheap as it gets. A couple of years back it was easy to pay well over $6.00 for 91. The way I look at it is that if I need to use premium gas then I want the car to use as little as possible. Not sure that I would ever be worried about a $5.00 difference in a fill up though. At once a week that is a whopping $260 difference over the course of a year. I piss away more than that in coffee. If that difference is a make or break consideration then you need to look closely at your finances.
Cars that need premium gas make power through compression. Compression causes knock. Knock destroys engines. The only way to combat knock is the use a higher octane gas. To make the same power on regular gas then they need to change much of the car.
