Premium has been recommended for the Si for a long time now. Not sure what the big deal is, I figured it out for 12,000 miles a year and the difference is about $120. If the $120 is that important to you, then there is no reason to opt for the Si.
here, premium is $0.30/gallon more than regular (some stations it's still only $0.20/gallon more, but none in my immediate area), and on average I run 2 tanks a month through my Si, and it's usually right at 10-11 gallons per fillup. So I'm looking at a price premium of $6.00 to $6.60 per month. If you double what I'm doing in terms of mileage, that works out to about 1100-1200 miles per month, 4 tanks, and a $12.00 to $13.20 monthly premium. I don't ever sweat it. I can't remember the last time I spent over $40 filling up my car. I know it's happened once or twice when it went over $4/gallon but it's been a long time.
We run about $.20 more out here. I figured a $.20 premium at 15,000 annual miles, and 30MPG. I came up with $100, so figuring that I get better than average MPG, I added 20% to be safe.
The other thing I don't think most people consider is that as gas prices rise, the price premium for premium unleaded remains fairly constant, which actually decreases the cost difference as a %.
