It's been almost 3 weeks and I finally went to the pump today. I was hoping to go a month before filling up but we didn't get the level 2 charger set up until a week after purchase. As with many others who have reported inaccuracies with the range estimates, I got a nice big (false) number...641 HV range. I wonder if it uses the average mpg in the calculation - mine's at 161.5 mpg. The car took a little over 5 gallons of gas. I have some photos but will need to figure out how to upload them to this site (if that functionality is available.) Otherwise I'll need to find a place to host them. So the reason I started a new thread on this topic is because I'm thinking about documenting my range estimates as an experiment. I'm starting a new job tomorrow with a 50 mile commute, one way. Both starting and ending locations are near the freeway exits so it will be almost all highway miles. However, in Southern California traffic, it will take approximately 1.5-2 hrs each way. If this community is interested, I can post my daily range numbers here. Please vote to let me know. I'm hoping I can go a whole work week on a tank of gas but now I'm a little concerned about it because I don't think there are charging stations at my new office and the car's range estimates can't be trusted. I don't want to be caught out of gas on the 405. Is there a fuel notification light that will come on when the tank is low? If so, how many miles are left once the light appears?
