P&G - how wide of speed is needed?

[a8ksh4]

I used to do a lot of P&G between 50 and 60 when I had a long commute to school. Also, any time there was any downhill, I'll pop into neutral for a cost. That's where I got most of my gains. Steady speed on the uphills (higher load for motor while it's pushing and storing kinetic energy) and then neutral for the downhills.

For those of us with auto (dog-a-matic) transmissions, you might check to see where it will shift out of top gear and end your glide before that speed. With my RAM, it will shift into 5th at 45mph, but I can sometimes get it to coast down to 40mph before downshifting...

P&G, something I've really not tried yet. I'm taking notes here.

My car is a 94 saab, can't use scan gauge. I pg all the time, but I don't know if it works or not. Accelerate. hard up to 75. Coast to what ever speed when the car behind me starts catching up. I,m thinking on lowering my idle so my coasts sip less fuel. Sc

That's the same for me. 55-25 when traffic allows. Obviously can't get away with less than 50 mph safely on the hwy most of the time though.

I think that it is funny how people suddenly develop road rage during a normal conversation inside somewhere when I mention driving fifty-five miles an hour.

Calm down!

The suggestion for acceleration is 3/4 throttle based on a 1970s BMW study of fuel economy.
