IMO, the biggest advantage of using quality gasoline isn't seat-of-the-pants drivability or fuel economy - It's how long the car lasts without requiring fuel-system-related repairs (i.e., injector cleaning or replacement, cleaning the deposits on the back of intake valves and piston crowns, figuring out why the Check Engine light is on, etc.). If using top-quality gas keeps the car out of the shop for a couple extra years, it's money well spent.

Can you get that locally somewhere?[/quote]Your best bet is probably by mail order. My local source (an independent repair shop) charges almost $25 a can; I just picked up a 12-pack on ebay for around $9 a can, including shipping charges. If you plan on keeping your Infiniti for a while, it's definitely worthwhile to stock up.
Here's a link to an ebay search for BG-44K that turns up pretty good results.
