Fuel log and mileage tracking app for Android

When I create a new entry, I can only tap on the text "add to favourite" and not on the star
If I tap on the star nothing happens, I have to tap on the text to select/deselect a favorite. It's just a minor inconsistency, at least it wasn't quite clear for me and I had to tap 3-4 times before I recognized why I couldn't add a favourite (I always used to tap on the star)

Sync with google drive seems to work, but some time later and without notification
Hi,
Since it works somehow, I decided to post this as question and not as bug.
Prerequisites:
- Google Drive Settings:
-- Autosync on change: true
-- sync between devices: false
-- activate notification: true
When testing this app for the first time, I always got a sync-notification nearly immediately (I had WIFI when testing this).
Then I imported 108 entries of another app on my own with some csv-conversions. Everything is now in fuelio, so far so good.
Today my first real time test with a new entry, I didn't get a notification (I didn't have WIFI, but mobile, if that matters), but it seemed to get synced an hour later (at this time I was already at home with WIFI, if that matters).
So my question: If the "notification" item is ticked, why didn't I get a notification, though my data got synced? And why would it last so long, does it wait on WIFI? Any idea? I'll turn notifications off in the future, but for now I just wanted to know how reliable the sync is.
Thanks!

The distances at Bi-Fuel are not calculated properly
First of all, thanks for this awsome app!
Now to the issue: When I use a Bi-Fuel-car (and have correctly activated two fuels) the distance count is seperated between the fuels.
For example I started at 85000 km and refuel CNG and petrol (95+). Than I drive some weeks and only refueling CNG. Than also needed to refuel petrol additionally to CNG. So I did two entries with the same date and the same distance.
Now comes the trouble: The app refers the entry for petrol to the former entry for petrol and not to the last entry. Therefor it calculates a faulty value for the distance (it takes the actual one and compares it with the one of the last petrol refill. This is wrong. So also the resulting calculation of the petrol consumtion is wrong (about 0,41 Liter per 100 km :-).
Here the table:
Date/Fuel/DistanceCounter/Calculated additional distance/amount of fuel
2017-10-27/CNG/86243km/+258km/10,17Liter
2017-10-25/CNG/85985km/+390km/11,66Liter
2017-10-25/Petrol/85985km/+972km/3,94Liter
2017-10-20/CNG/85595km/+249km/8,79Liter
2017-10-18/CNG/85346km/+333km/9,28Liter
2017-10-16/CNG/85013km/+0km/FirstFullRefill#2/3,16Liter
2017-10-16/Petrol/85013km/ /FirstFullRefill#1/1Liter
So the error is to substract the petrol-distance-values from one another.
But the distance value is independent from the kind of fuel. Therefor the calculated additional distance should be always generated by using the last and the second last distance value.
It would be fantastic if you could correct this. :)
And by the way: CNG ist handeled in Kilogramm, not in Liter (but this is only manicure).
Best regards,

Price of a car
It would be nice if there was a dedicated field for car price (when buying and selling the car). That way we could know full costs of a car.

Statistics, Charts, Cost stats and Cost charts does not work on Android 7.1.1 (Nexus 6, August patch). App is crashing.
App is working great, except when I choose "Statistics", "Charts", "Cost stats", or "Cost charts".
After few seconds of "thinking", App crashes.
Device is Motorola Nexus 6, Security patch from August 5th.

Logging only mileage (no fuel)
I need to write down odometer count every friday evening and sunday evening to log my weekend rides. I have been using this workaround in Fuelio to save odometer count that I put amount of fuel to 0.00001L (close to zero).
Could there be such feature (or there already is?) that I could just fix my odometer count from time to time without having to fill fuel ? It does not work if the amount of fuel is zero. But it luckily works if it is 0.00001L :)

Switching order of entry fields
Hi! Great product! Would be just a smudge better if you allowed us to pu in cost per fuel unit before we put in number of gallons (or whatever unit of measure). If we can put in the information we know first, then fuel consumed, it would save time and hassle.
Thanks!
