Wanna throw a piston?

In this article debunking myths about gasoline-saving techniques, Rik Paul from Consumer Reports says with a fuel-injected engine, engine restarts don't use extra fuel.

Granted it's probably not sensible shutting down the engine every time you get stuck in traffic, but if it looks like you might be at the drive-thru for more than 30 seconds to a minute, it's worth turning off your car, says Paul.

Sounds great. I'll turn my engine off just long enough to let the oil pressure drop and a good portion of it return to the reservoir. Then, I'll kick that baby back over. And I'll just repeat this over, and over again. Sure, a modern engine probably isn't going to rip itself to shreds just because it's got a little extra friction, but for a 30-second stop? Really? Does Rik Paul rebuild engines on the side?
