I have put 4200 miles on the car and put in about 20 gallons. That is equivalent to 210 mpg, which is probably lower than many other Volt drivers. 1000 mpg is definitly doable.

I drove over 1,000 miles on just .6 of a gallon of gas. The .6 was used was from the engine recycling several times through the system to make sure it didn't sit and stagnate. Finally broke down and drove further than the electric range and now have used 1.7 gallons of gas. : ( I don't plan on filling up anywhere in the near future. Maybe not until 2013!

I have owned my car for two months and used 8 gallons in 2700 miles. (337 MPG). Most of my electric driving is from charging at work, so my electriciy is free! Funny story - most Volt owners don't want the dealer topping off their tanks if they go in for service because they want to see how far they go on the first tank of gas. Luckly my dealer asked me if I wanted gas when I when to get my lic. plates. I smiled and thanked them but said no. LOVE MY VOLT!!!!!!!!!!

The dealer gave me a full tank of gas when I bought the car 2200 miles and 2.5 months ago. I still have about 20 miles worth of that original gasoline in the tank, Aside from day to day driving to and for work I have done one road trip up to the lodge on a nearby mountain. About halfway up the mountain I switched to gas and did 20 miles in gas mode. Best part of all though was coming down the mountain where the regenerative braking systems completely recharged my battery in about 30 minutes.

My work mileage (about 200 miles a month) is reimbursed at .55 cents per mile so I have that money going into an account that I will use to pay the additional cost of electricity ($45 a month) and the occasional trip the gas station. When the lease is up I should have a few thousand dollars in there to help me with whatever my next vehicle choice is... most likely the new and improved Volt.

We got our Volt in early March. Now it's mid-July. My wife is the primary driver. The car has 4,600 miles clocked (average roughly 34 miles /day). So far we've burned 3.2 gallons of dealer gas. Have not refueled. The engine did turn on for maintenance mode once, using 0.1 gallons.

We still have half the tank that came with the car when we bought it 11 months ago.

Here is my report after owning 2012 Volt #2394 for one year.

The statistics:

7,227 miles; 5,862 all electric, 37.9 gallons used over the year; Lifetime mileage: 190.5 mpg.

We monitor the power required to charge the car and it has averaged 4.90 kWh/day (1,790 kWh/yr). Part of a low-energy house.

My electric range at the start of each day has averaged 43.0 miles and my daily commute is about 24 miles.

I've stop by the gas station about every four months.

Really, I don't miss it!

I drive 90-95 round trip commuting with no re-charge station at work. I have had my Volt since April (~ 6 months as of right now), I have put 18k miles on it and averaged 64.8MPG. I fill up about once every 6 days. This is about the worst commute one could design for a volt but I only put in 8-8.5 gallons once a week.

I do get better than 35 miles on my battery though, I have been getting around 40. Although in the last two weeks, when crusing above 35MPH I have been turning it to mountain mode to let it recharge the batteries while I am cruising above 30MPH in steady traffic. Once I get within 15 miles of my house I turn it back to sport to run on batteries the rest of the way. It seem to be more efficient charging this way and will add about 10% better gas mileage but it's only two fill ups so it's hard to say for sure.

Also, 100% of the time I drive in L, it is so ideal for traffic. Just let off the gas at it starts to slow down like driving a manual transmission. It saves brakes and recharges the batteries better. It takes about 3 days to get used to though.

We drove 9000 miles and used 2.5 gallons. We got 3600 mpg at that rate.

Then, 1 week before we had the car 1 year, the computer forced us to burn gas. That went on until we were down to less than 1/4 tank. It took 7 gallons to refuel. I used ethanol-free (90 oct.) to re-fuel.

I guess that you can't go over a year without getting gas.

Similar results from anyone else? Car has performed flawlessly in over a year.

Drove all-electric for past 3 months, was at 219 mpg lifetime, but used 5 gallons over last 2 weeks, due to a several long road trips to meet clients. Dropped to 180 mpg lifetime, should start climbing back up as I don't anticipate any long road trips for the near future.

After 8 months, my Volt has 4600 miles and has burned about 3 gallons. With the PG&E EV time-of-day rate plan, the electricity bill has risen a few dollars a month. The low number partially results from being in an inexpensive electricity pricing tier.
