I....like most of us....am a fairly new clarity owner. Running a vehicle with little gasoline is bad for the engine, bad for the fuel system, bad in general. Our gas tanks are pretty small however....7 gallons? I can't get to work and back on a single charge so I must use some fuel..... I'm wondering..... when do people put gasoline in their vehicles? I'm thinking.....50 miles gas range? That would be roughly 1 gallon of gas left in the tank? What are people thoughts?
