Run it at stock pressure.
If you want to save a buck on gas, buy it in bulk whenever it's cheap. That has a LOT more to do with your cost per mile for gas than your tire pressure.

Buying bulk gas cheap sounds like a pretty good idea, but that requires preparation, a large initial investment, and continuous maintenance of a large gas tank. I'm sure it could save money given a long enough payoff period, but its probably more than most want to do.
Also, the manufacturer recommended tire pressure is usually set to optimize comfort above all else. If I followed the recommended pressure, the edges of my tires would be bald by now. I run 51 front, 47 rear. The tire pictured is a front tire with 3-4 /32nds of tread remaining. The edge wear is still outpacing the center tread. It has been run its whole life at high pressures, but has been rotated several times already.

Unsafe handling is on a per vehicle basis. I get plenty of grip and predictability at high pressures.
Underinflation also ruins tires and can screw up handling.
