Need some validation for logging entries

Unless this van has trans problems and only 1st and 2nd gear left, there's no way this person got only 4 and 9 MPG their last two fill ups, and the erroneous low numbers skew the data for the vehicle as a whole by several MPG with such a limited number of data points.

Wow, of the two vehicles of this year and model, they both have invalid data, because I'm sure this owner miraculously got double the MPG they were getting on average, as opposed to forgetting to log a fill up and using two tanks full for the 556 miles and 33 MPG they recorded.

Check another year, find more bad data

Best not look at some of the best Euro diesels either because some of them are pulling close to 100 MPG now with clever driving!

Thnaks for pointing out that other fuel-up issue on the second car there. Fuelly was setup as a very simple way for people to track fuel economy with very basic limitations in place for data quality checks. This was done on purpose by the founders but it's clear we need to evolve and put some more logic in place to identify and handle these issues. We'll be developing some algorithms to identify these out-of-bounds fuel-ups and notify the owners on a suggested fix. Once the new algorithms are in place we will also use them when data is being entered to hopefully get them to fix the input when it's happening. We don't have an ETA on this new system but hopefully it will be fairly soon. We just moved to a new tech stack a couple months ago and are almost settled enough to start working on new functionality like that.
