2 Decades ago I picked up a fuel saving add-ondevice in a flea market for use on carbies. It had a solenoid to cut-out the idle screw thus cut-off all fuel to the engine when the engine rpm was greater than 500 rpm AND the acceletrator pedal as fully up. i.e. when coasting down a hill, or decelerating, the engine consumed no idle fuel to keep it ticking over. It worked a treat and did save fuel during stop/start city driving, and also during country driving on hilly terrain.
Since then I’ve assumed (but no longer) that EFI in a modern engine would be programmed to do likewise

Well sure. That’s one of the main reasons why hybrids get such good mileage. They auto stop at stop lights and signs. Take your foot off the brake (or clutch) and you’re off again. That saves more gas in city driving than a MPG or two because of aerodynamics or engine design.

It’s not hard on the starter at all. That’s an electric motor, so what’s to wear out? It might be hard on the battery if you kept doing start/stop cycles with no chance to recharge.

And it doesn’t take measurably more gas to start a modern fuel-injected engine when it’s warm. If you’ve got an old car with a carburetor, and no feedback loop in the emissions control system, then it might. But the proof is by experiment, as in the article. If someone can drive the same except for not idling, and greatly increase mpg, then how can the car be using more gas to start?

I’ve done this before. And even left the engine off while creeping ahead while my car was on a down hill slope.

I was SOOOO proud.

I do have two questions:
How hard is it on the car’s starter to restart the engine 20 or 30 times every few miles?

Does it take more gas to start the engine than it does to idle for, say one minute?
