@Roman: (I can probably say that) all the cars that use the fuel injection, stop delivering fuel when you lift your foot up from the accelerator pedal (unless the engine is in really low-rev). This also holds for our Hyundais - drive with someone that has a trip computer with the instantaneous fuel consumption and you'll see it directly.
Thanks Neoto, you've answered exactly what I was going to ask next. I have a mate driving brand new Camry (auto) and even he shifts it to neutral for the same reasons that I've explained earlier on... We're playing tennis tomorrow, so will definitely discuss this. He's got the instantaneous fuel consumption computer... will observe.
I think it's just the bad old habit from the olden communist days, driving Lada 1800 in the former Czechoslovakia!!
Gee, I'm so glad I've joined this Forum. So much useful info
