Cool thanks for that .
I ment once you have let go of the ign key once it's fired up. Cause I notice my fuel gauge move a little downwards once I have started my car up lol. Cause I seem to be using less fuel doing a twenty mile trip to work going the long way round to Torpoint from Plymouth than starting and stopping my car whilst queuing and getting on and off for the ferry over to torpoint in Cornwall. Weird ????.
