So…we own two vehicles. Dave drives the Toyota Prius to/from work (20 miles per day), while I take the boys around in a Honda Odyssey (more than 20 miles per day, usually closer to 50).

Don’s blog now has an RSS feeder streaming his favorite news articles related to Electric (EV) and Plug-in Hybrid (PHEV) vehicles. I also noticed our local Citgo station’s unleaded gas (corner of Penny and Ten Ten Rds.) is going for $3.29/gallon (look here and scroll down to the list of most expensive gas…and YES PAUL, that’s Costco with the cheapest gas in the area!).

It got me thinking: how much gas (read: how much money) could we save if we tried to live with one car for a while…just the Prius?

Right now we average 1 tank of gas per week for the Prius (about $28), and 1.5 tanks of gas per week for the van (about $75). I wonder if we could do everything in a week on 2 gallons in the Prius?

Could we save ($28+75) – ($28+$28) = $47 per week? $200 per month? $2400 per year?
