I’ve had 2008 crossover from brand new for 3 weeks now and my mpg is all over the place. It says I’ve got 105 miles in the tank. Go for a 3 mile trip , then it says I’ve got 85 miles left. Go for another 5 mile trip then it says I’ve got 63 miles left. It’s been back to Peugeot . They rebooted something. But still the same. I’m scared to go on a long journey in case it runs out of petrol . What do I do.
When fuel computers calculate remaining range, they tend to do so based upon the mpg achieved during your most recent journey. If you are doing very short journeys in cold weather, your mpg will be appalling and hence the remaining range will drop, as it will be assuming that the remaining fuel will be consumed at the same rate. However, if you suddenly go on a longer (more fuel efficient) journey you will find that your remaining range starts to climb markedly.
