Kia Ora. I have a Prius plug-in hybrid which is doing as planned around town where it runs pure electric almost all the time. This means that in the last 2 months I have done 1500km and used only 4-5 litres of fuel according to the computer. Does fuel go stale over time and so should I make sure the fuel in the tank turns over regularly?

Hi there,
Fuel does go stale but after quite a long period of sitting around. I would recommend adding a little bit of fresh fuel every few months for best results.
