Filled the tank up this morning, have driven the car about 10-15 miles or so on a roads and my range has dropped by about 70 miles. Any ideas what could cause such poor mpg? Didn't drive the car any harder than I usually do and its a fairly regular route I take and I only noticed when I looked at the needle when pulling onto the drive and it was just over 3/4.
The trip computer calculates range based on the consumption of the last gallon or so, so if you were running low and nursing it then it would cause a unrealistically high range, then booting it for 10-15 miles would cause it to drop?? Just noticed you've own for a while, prob best ignore my comment
Its just unusual for it to go from a full tank to just over 3/4 on a shortish journey which didn't involve any stop/start. I'll see how it gets on this week first before I try to diagnose anything.
