Anyone from Europe know if this is the case - Piwoslaw or Euromodder ? My current tank is a complate failure at -4-5 MPG on each trip and each "bar" on the fuel gauge going about 10-15 miles earlier than before - that little HM badge below will be going soon
Another factor though is that the weather is much colder - hard frosts now but no snow yet. Lots of rain. I've taken to parking under the car port and pushing the Prius back as far as it will go to get them both in.
