For nine years we drove a Skoda Octavia 1.9TDIs. We downsized to a Fabia 1.6TDI expecting to get increased mpg but have been sadly disappointed. The Octavia usually averaged 52-54mpg and sometimes almost 60. We have never achieved these figures in the Fabia and during one test, full tank to full tank on motorways and A-roads, it returned 47mpg. Is this normal for this model or should we achieve more than this? Skoda garages and Skoda technical staff blame our driving.
