Hi. I'm driving conservatively and getting around 59.5 mpg. 100 miles a week motorway and 50 around town. I have the instant fuel consumption on the dash all the time. If I'm driving in fourth gear at 30mph on a flat road I get between 60 -75 mpg, when coasting 99.9. Once a month (on the same journey) I notice coasting is at 70 and the 30mph is down to 43mpg. If I coast round a corner, it drops to 50mpg. I know it sounds strange, but I knoe the car. It seems like it gets a cold once a month. Is the cold start sticking? Any advice. I can afford the extra 50 pence of fuel a week lol, just niggling me!
Thanks
