US MPG Calculation Wrong?
The MPG I'm seeing in the app is significantly higher than that which the car itself is reporting.
| Odometer | Fillup | Travelled | my MPG | Fuelio MPG |
|---|---|---|---|---|

| 119659 | 8.701 | 370 | 50.68 | 58.73 |
| 119289 | 6.240 | 274 | 59.29 | 50.99 |

Are you sure you have right units? :)
Make sure you have full fillups. Some time ago I've got similar report and the user set UK gallon and UK mpg.
Please, check your settings.
Great! I'm glod it works fine. I think I can add better detection for units. For sure.
Perhaps a check, something like "I see you're using US Gallons but are calculating MPG the UK way. Do you want to change that? [Yes, take me there] [No, I like to have confusing metrics] "
That was it. I was certain I'd set fuel units to Gallons (US) and Consumption to mpg (us), but it wasn't. It was set to mpg (uk). As soon as I made the change, the numbers look "better".
Miles are common.
Try also delete app's cache using this trick:
1. Go to Add Fillup screen - tap add with empty form
2. You'll see error - Go to Menu / Stats
3. Go to Fuel Log.
It was my logic that was in error. I needed to take the Travelled value (in Miles) and divide it by the CURRENT Fillup value (in US Gallons) to get Miles/Gallon ("my MPG").
Our numbers don't perfectly match, but of the 11 items in the example, we're off by an average of 0.01. Close enough for me. :)
Thanks for helping with this! Love to see developers who actually talk to their customers.
