There are already quite a few threads discussing fuel type and mileage. Some of them are (in no particular order):

My car cost close to $50k so she deserves to be treated to premium gas.

I agree with you there. So far after 2 tanks we've averaged only 16.5 mpg. IMO, that's terrible but she's new and we idle her a lot while playing with all of the gadgets. It's mostly city driving which matches the sticker's expected mpg (16-23 AWD), and the A/C runs all the time.

I plan to run the first year with premium and then switch to the cheaper fuel for a comparison.

Thanks Dividedhighw for the compilation of MPG posts.

What really matters is compression. High compression engines will more than likely require a higher octane rating. In other words, a fuel which is more resistant to spontaneous combustion, auto ignition or detonation.

Want to increase your fuel's octane rating? Just add water! Nah, don't do that to your Infiniti.
