P&G on an AT

AT's can only be P&G'd if they are flat towable. Search that term and you'll find charts listing flat towable cars.

The Yaris can be safely used for N-ICE on gliding as stated above and it can be used for P&G'd at lower speeds on flat roads as per the manual.

Obviously, since I don't shut down the engine, what I'm doing cannot really be called pulse and glide - and since I accel to 60 and coast in neutral to 50 I'm wasting effort?

Also, what is N-ICE?

I've been doing this for 250 miles. Maybe I'll go ahead and fill up early just to see?

"NICE on" is coasting in N at idle... engine on.

Voodoo is right. Technically a P&G glide is done with the engine off. The same principals still apply, but are less efficient because the engine is idling during the glide.

P&G with an AT may truly be NICE on coasting. The same concepts apply to both. There is very little AT specific info on NICE on coasting techniques at YW or at cleanmpg. However, one can learn from the basic concepts of P&G and apply them to NICE on coasting. Sorry to blur the terminology. P&G NICE on should be a term if it isn't.

IMO, at highway speeds, P&G NICE on can be tricky even with a ScanGauge. At speeds over 45 mph, there is more wind resistance, so the frequent accelerations and shorter duration glides, can cost as much as the coasting benefit. Not to say it doesn't work, it does, but it takes more focus.
