I disagree with how Fuelly displays its MPG; this is really only an issue in the context of a feature I'd love to see on the site: categorizing fuel-ups by gas station [more inside]

It is reasonable to use average MGP (mean value) for one car. However, median value makes more statistic sense when calculating MPG for a group of cars. I saw people entered unrealistic MPG for their car. It may significantly pull the average MPG up for their car model. By using median, the unrealist MPG is just one sample point. If all other samples are real, it won't impact the overall result much.

I'm having trouble adding fuel-ups on my motorcycle. Whenever I enter the values below, I get this error: "Looks like the price you entered for a litre of gas is unrealistic. Please enter a value less than $15.032".
--
Kilometers since last fuel-up: 167.6
Litres: 6.955
Price/Litre: 134.9

Unfortunately in Canada, that price for fuel isn't uncommon. Whenever I refill my TDI it accepts these higher values.

How do I resolve?

Is there a way to weed-out the bad entries? I see people are too ignorant or careless and you end with erroneous numbers that alter that averages and ranges?

Is it possible to filter the cars in the database by location? I want to find all other cars registered here that are in my country, Iceland :D

I'm leaving tomorrow for a trip from Akron Ohio to Fort Pierce Florida and used the GasBuddy Trip Cost Calculator today to estimate the gas cost for the round trip.

It was astounding and annoying to discover that gas prices drop a lot after leaving the Akron area. For example: the price of gas near where I live was $3.89 for regular this morning. According to GasBuddy, it's $3.25 in Bastian VA, $3.06 in Rock Hill SC, and $3.22 in Richmond Hill GA.

In fact, according to GasBuddy, gas prices are 35 cents a gallon just twenty miles due south of here...

This is all truly disgusting: the economy in northern Ohio is a disaster. There are few decent jobs here now, home foreclosures all over the place, and homeless people begging on street corners.

Given all this, why are gas prices nearly a dollar a gallon more here than they are 500 miles south? That's a question I'd really know the answer to...

Hello All,
I thought you might be interested in a current hypermiling challenge ('til end of May) on a new platform, Luum (dot com), that lets you create friendly challenges to motivate participation and sharing for real world impact.

Our objective for this challenge is to get people to try some basic hypermiling techniques, but all levels welcome. Participation is free and we'd love to have you try it out.

Thanks,

Hey, I'm new on fuelly, having just bought a new car, and I am having a strange confusion with how this works...

When I got the car, I put in £30/22.5l of petrol, and drove about 180 miles.
I then put in another £30/22.5l of petrol, and then on fuelly I entered the following details:
"distance 180 miles, 22.5litres of fuel"

Today, after another 185miles, I went and actually filled up my tank to the brim (39.14litres). I went into fuelly and entered:
distance since last fuelup - 185miles
amount of fuel - 39.14 litres

...and it comes up with a fuel economy of 26mpg. Which is incorrect, because what I had actually done was 185miles on 22 litres, not 185miles on 39 litres which seems to be what it is calculating from.

Am I supposed to wait until the tank is empty again, and enter that mileage figure into fuelly with the "39..14litres" figure?
