100 octane would be a waste of money most likely (usually stuff above normal permium gets really spendy). If you were running a hot turbo setup you'd probably want the higher octane.

Not exactly the budget buster some people seem to think it is...
I suppose thats true. All I know is where I'm at, I couldn't make the money I do without driving, so it evens out. I don't even bother buying regular, I just use my Shell card and get the 5% gas rebates. It works out to the same thing pretty much.

I don't drive as much as my example would suggest either, the average gets severely skewed by stop and go rubbernecking highway traffic during the week, and lots of free highway cruising on the weekends. 20 - 25k miles a year. I guess for people who drive 70 miles a week instead of 70 miles a day, they should stop being cheap asses.

Then again, while it may only be $120 a year, any and every penny you can save these days is worth it, the way things are going. You could be earning interest on that money. Gas isn't the only thing getting ridiculously expensive these days (food prices?). I'm betting a lot of people who buy these cars don't run them flat out WOT all the time, and probably don't need to run >= 91 to keep the things alive.

It's really a waste of money to use that. Especially at that price.

Wasn't sayin' that it was a good idea one way or the other, just that the difference in fuel cost is extremely negligible compared to the total cost of ownership with depreciation, consumables, and insurance. Hardly worth considering.
