low mileage on start-up?

Every car gets terribly bad gas mileage when its engine is cold, including the Prius, because the engine needs to be hot to operate properly, even regardless of pollution issues. Oil viscosity, among other things, is much higher when the engine is cold and is responsible for more friction.

What the Prius is trying to tell you when it displays the 5-min consumption bars is : "What the hell do you need me for a 3 mile trip ? You'd better walk or take your bicycle instead ! That would be better for your health too..."

It's not only a car, it's a learning device. :wink:
