    I just put gas in my car for the first time in about 3000 miles. I only used 6.8 gallons of gas. After putting in the details, the MPG doesn't show up in Fuelly.com. I don't know if there is some limitation on max MPG it will calculate.

    I am just wondering if anyone else is experiencing this or not.

    Perhaps it didn't believe you since Fuelly still doesn't support PHEVs. :D

    Seriously though, the first time I used it with my PiP, it said something like, "Are you sure about that?" And that was only about 95 mpg. I do wish they'd figure out how to support these increasingly popular PHEVs.

    Make a spreadsheet and set up the formula within the spreadsheet to do the calculation for you.

    mpg = miles/gallons

    I find it easier to track the odometer reading because the dealer tech often resets the trip meter when resetting the maintenance required light when servicing the car.

    The spreadsheet can also calculate the miles driven between fuel ups from the odometer readings and plug that into the distance traveled cell for you.

    Like Fuely, you can add cells to input the cost per gallon and have it calculate the total price for the fuel up so you can use that as a check to see if you are entering the right values for the distance, price per gallon, and gallons.

    Good ploy, I do the same: trip meters are too volatile. Fuelly also will allow you to enter odometer value, and subtracts it from the previous.

    I'm belts and braces: update my spreadsheet first, then Fuelly, just for fun.

    @Captmiddy : all I can think is to contact Fuelly, let them know your issue, with the details of your extremely low consumption, see what they say.

    I actually entered it by odometer reading not by calculated delta on miles. I have had a couple resets on my trip meter since I put in the fuel because service people can't seem to figure out they don't need to touch the trip meters to do their job. I will likely contact Fuelly but I am surprised given the Volts have been around several years now that they haven't already corrected this issue. My most recent usage of fuel will seem more normal since I just did 400 miles today for travel to family and back home again.

    I think there is still the issue of measuring the energy usage with this car, no easy way for me to determine that. Getting a true cost of usage would require me to know this information. That said, I am still living on borrowed time with the overage from my solar panels. That will go away in another month or so.
