That's true. We added the Prius plug-in before we realized they'd be reaching around 200 MPG/fuel-up. They've sort of been grandfathered in at this point. We're still considering removing them from the public directory.
We don't want to remove the limit because we'd suddenly have a lot of cars getting over 200 MPG due to data entry errors. They happen all the time. We'd rather show nothing there so people have an incentive to fix the problem.
Requiring a second confirmation step isn't a great option. We allow fuel-ups via SMS and Fuelly Mobile where it's more difficult to have that sort of back-and-forth interaction. We'd rather keep things simple because over the vast number of people fueling up here the simple approach works better and ends up with better data.
I hear you and understand your frustration. We're just not ready to support plug-in electric vehicles right now. It's something we're thinking about. If we do it, we want to do it right—not have halfway hacks that sort of work. Again, sorry we can't support your car right now.
I made a few monthly entries to reflect my charging consumption, using 33.7 kWh as the equivalent of 1 gallon of gasoline.
I guess what needs to be added is some way to support duel fuel tanks. I have duel fuel tanks one of my farm trucks so I don't think it is unique to plug in vehicles. I edited all the fuel ups to be partials.
I had dual fuel tanks on my F-150, too. All I did was fuel both tanks at the same time and use the total amount of fuel. It doesn't matter whether thirty gallons goes into one tank or two. The place it would make a difference would be a vehicle which can use two TYPES of fuel, whether propane/gas or electricity/gas.
I usually don't fill up both tanks, just the one I emptied. I figure I want to go through the other tank and burn the older gas rather than blending it with fresh gas. I used to pay attention to having one tank with the current seasonal blend if I took the truck into the city but I don't take it off the ranch anymore.
Converting kWh to gallons seems to be working. my "mpg average" is more or less reflecting MPGe.
I think I might put together a simple smartphone app to do the conversion on the phone and SMS the fuelly update, keeping the original kWhs in the notes.
"odometer" "gallons equivalent" "gallon equivalent price" "net kWh, gross kWh, total price of charge"
