That's what I thought a Pulse and glide cycle was - if so, what am I doing wrong as surely, you aren't sitting there on the clutch every 15 seconds engaging gears (or in EOC, starting the engine)?
its how I PnG, run it up to speed then coast with the car in neutral until Im 5-7 under, rinse repeat.
I did this behind a fairly large truck that was running 5 under, and I think I averaged close to 50% increase, but I did it only because I was in a bad spot when my fuel light came on with no recourse but PnG or run out of fuel
