I don't know if some already talk about this on the forum, but I have a question on this Pulse and Glide technic. Yes it's good in theory and all, just like when I'm going downhill I WAS putting my VX in neutral. But then I thought about that, when the car is running in neutral, the gaz isnt burning the same way then if it would be in gear, so I told myself, well I'm better be in gear, even if a burn a litle bit more gaz, at least its going to be more clean for the air.

So what do you, people of gassavers.org have to say about this, because I really dont know what to think.

So long as the engine is running, your emissions system will still inject enough fuel to keep the catalytic converter/s running as they should be, so there shouldn't be any change in emissions. In fact, your emissions will be proportionally less w/ the car in N provided you're getting however much better mileage. When you shut the car off, the cat/s can cool down to the point where a significant rich excursion is required on startup, which would result in more, possibly way more, HC emissions. So unless you kill the engine, your emissions should be roughly the same. :thumbup:

Well I know what I'm going to do, shut off the engine when I'm going downhill! On a 70km trip, I'm doing like 5km, at least, on downhill. This is going to be a great save of gas, of money and also the mileage of the car, even if I don't think I never will sold this VX.
