Having owned a vehicle that needed premium fuel... I can tell you that if you don't, the onboard computer knows it. Before you'll ever feel the engine start to ping, it'll retard the timing.

Bottom line, cheap gas in a vehicle designed for premium fuel = reduced performance. Go-go juice is expensive enough these days, having to pay for premium fuel was a poor choice for Toyota. Nissan squeezed out plenty of power while using crap gas. I wish my Jeep had this Nissan engine!

The FJ (called a "Fake Jeep" on Jeep forums...) is too cutesy for me. Major yuppie mobile though. Expected to see in mall parking lots everywhere soon... right next to H2s.
