I would like to see a palace to set a percentage deviation for cars running altered tire sizes. I have one that's equipped with 12.1% taller tires, and this would make the calculation much simpler. Is anyone else running different size tires than normal and in need of such a feature? Is this something that might be added later?

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 was interested in checking out the average mpg of a VW Golf. I was surprised to see it so much higher than the U.S. EPA estimate. Then I realized that much of the data is coming from non-U.S. sources and that it may be reported as Imperial Gallons. Are the U.S. Gallons and Imperial Gallons mixed together when reporting? Or is there a filter to show the results in one vs. the other. If they are mixed, then I don't know how I could use the information I am getting.

Thanks!

Please, Please, PLEASE - fix your iOS app so that it doesn't crash every time I try to look up the stats in my 'Garage'!!! UGH! I really want to fully use the app but it's so very frustrating.

Great site. How about an entry for cost of services, oil, new tires, etc., so you see the true OPEX of owning the car.

I have entered 7 fuelups for my tdi diesel. I displayed total gallons used and calculated the mpg. 2553/81.02=31.5. I am using odometer so I subtracted the first fuelup 15.56=65.46. 2553/65.46=39.000. I still see an avg mpg of 55. How do you calculate the mpg? I know it will get better with more fuelups but I would like to know how you calculate it.

thanks

I find it very useful to be able to add fuel price to 3 decimal places allowing me to add a price per gallon of £1.429. But it is very strange that the calculated amount also has 3 decimal places (£76.452) since I am unable to pay with that much accuracy. I am not aware of any currencies that allow payment to 3 decimal places. And for some currencies only 0 should be allowed (there are no cents in a Yen for example).

Please add time of day on Add Fuel Up screen, instead of defaulting all fuel ups to 12AM.

I was looking at the 'Recent Activity' on the side of the page, and went to "TruckerPaul's" page to look at his semi-truck. Then I wanted to see if there were any more like it, but his vehicle type does not show up when looking at the 'Browse Vehicles' page. [more inside]

Ok, I may not be the sharpest but I dont believe I am that stupid either and I cannot figure out how I have skewed the figures on my account to give me an MPG of 38 when I know its around 24?

I have put in the details I had for 3 fuel ups, the first a complete one and the others partial, and marked as such. For my mileage I am using the odometer and I am sure that it is with this that I am doing something wrong as the mileage covered is missing out the first fuel up and so is out of sync, giving me inflated figures.

I have attemted to use the contact facility to establish how I have gone wrong and how to correct it but have as yet rec'd no response. Can anyone shed some light on this and point me in the right direction as I would like to make proper use of the site?

Thanks

Rob

I see Prius Plug-ind are at 140 and the C-Max Energy is also listed, but still Fuelly is discriminating against the Volt. Please list the Volt or de-list the other Plug-ins.
