Hello again all, thank you for your suggestions in the previous thread
I just tried pulse and gliding for the first time and it went pretty well. I'm still a bit wary of clutch wear as it seems changing to neutral and back to 5th every 15 seconds isn't the healthiest thing for the transmission, but I'm willing to give it a try for a tank to see if the difference is significant
I tried doing it tonight at night. My ignition has 3 positions and I ran into a problem.
1. When turning the key from "ON" (where the engine runs) to ACC, the headlights go off, only the sidelights stay on.
2. When putting the key back to "ON" to keep the lights on (necessary for safety), the engine starts up again as you'd expect, clutch depressed or engaged makes no difference.
Therefore I'm limited (without an engine kill switch) to just using neutral when on the "glide" part of the technique. I know neutral uses such a small amount of fuel by comparison to having your foot on the floor, but does this actually net a positive MPG result at the pump? In the day it would definitely be possible to kill the engine because well I don't need the lights and the steering isn't locked, just no power which is fine.
Also I'm just trying to work out my optimum speed. I get:
55mph@ 2600RPM
50mph @ 2400RPM
45mph @ 2200RPM
