Hey everyone,

So I tried coasting in Neutral yesterday on all of the areas where I leave it in Drive when I release the gas pedal. A few things I monitored...

-I coast just as far in neutral as I do in drive. It's no further. It slows me down at the same rate. I don't have any steep declines in my area. Just flat to rolling hill terrain.

-My UltraGauge shows 999.9 MPG while in Drive from 50 MPH down to 20 MPH. In Neutral, it shows 70-100 MPG at 50 MPH then declines from there as my speed drops. My Instantaneous Gallons Per Hour is .35 GPH while in Drive. It is .6 GPH while in Neutral. This is with no A/C on, nothing.

-When I shift from Drive to Neutral at 40-50 MPH, I feel a slight jerk and lurch. The sane happens when I reengage the transmission.

Based on this observation, it would seem that coasting in drive is more beneficial for my particular car than neutral. Is this strange? My UltraGauge is not calibrated.

One more note: On my last tank trip, I achieved my 37 MPG average using coasting in Drive. However, I also used DWL and no A/C as well.
