As a "newbie" here, I'm still experimenting with the P&G technique. So far, I've been able to increase MPG by roughly 10 MPG. My question is: can P&G be used on other vehicles, (i.e., ICE only)? I'm thinking it might with automatic transmissions, but unfortunately, my other vehicles have standard transmissions. Anyone with experiences here?
To add something that wasn't said in the other thread: automatics don't pulse and glide well because their pulses are inefficient. Your standards will be better. Automatic drivers are generally better off sticking to DWL.
Driving With Load. Trying to maintain a steady, efficient rpm, allowing the car to lose speed uphill and gain it down hills.
Please do read the thread that krelborne linked. And go to CleanMPG. Short answer, P&G works very well in a standard transmission car, that is where it was developed. I tried the engine-off version only enough to prove that it could be done, and to learn that it wasn't for me and my poorly-coasting Subaru. So I use only the engine-on version, and only when it can be coordinated with rolling terrain. Flatland P&G (still engine-on) worked better in the ancient and easier-rolling Honda that was being eased towards the scrapyard.
Having read the links provided by some of you, it seems that P&G in a non-hybrid (standard transmission) is really not worth the effort. For a minimal gain in MPG, shutting and starting the engine, or even putting it into neutral, would be hard on a car not made for it. I did run across a Click & Clack newspaper column recently that also give a bit of insight: Car Talk
This depends very much on you and the car. The potential gains are huge, as Wayne Gerdes regularly shows, if you are willing to put in the effort and it fits the situation. The serious P&Gers bump the clutch to restart while rolling, so they don't use the starter. With a bit of practice, it is very effective, smooth, and low-wear on many cars. It doesn't fit me and my Subaru, so I don't turn off the engine. But even engine-on P&G is still quite useful in this car for rolling terrain, gentle downslopes, and stop-and-go traffic congestion.
