Number of fuel ups is false...
 

There is no way this is correct. You really should consider updating how this calculates.
It does not take in the date of the fill up. Only when it's posted is taken as the fill up date.
I also don't know how it possibly comes up with averaging 4 fill ups a month? I do two.

When you add a fuel up, there is a section where you can put in the date of when you filled up, regardless of how long ago it was. Not sure about the "per month" query, mine is accurate at 1 per month.

I do enter the date. It seems to ignore it?

Can you add a bogus fill up (and then delete it) to see if that refreshes that count?

I'm not sure where it's pulling that number from actually since you have 2 fillups/month and 1 note/month.

Did you at any point add more fillups or edit/delete any?

I didn't add any. Don't think I did any editing after posting. Didn't delete any.

It seems it has been goofed up right from when I started. Posted two fill ups. Filled in the dates. It immediately posted two fill ups a week?

Since it is you who asked. I'll go ahead and post a bogus fillup today. Then delete it. I hope the mileage I guess for doesn't stay there....Doh!

Ok.... I added one...
It came up with 5 fuel ups a month.
Deleted it.
Went back to 4 fuel ups a month.
Everything went back to normal. No problems.

I'm noticing, it seems to be stuck on my number of fuel ups is only in one month?

I am wondering if deleting the first two fuel ups would correct this?
It seems posting them on the same date, but different dates for the fuel ups. That may have thrown your software for a loop?
I'd rather not do this. As this is a record of all my fuel ups since buying the car.
On the other hand. It would take away my low's. My average would show higher. Not to deceive. But eliminates when I lacked driving at all with mileage habits.

The date you add the entry doesn't matter.
We've had users import YEARS worth of data and it'll show they added 100+ fuel ups on the same day to Fuelly, even though each fuel up has it's own respective fill-up date.
Still looking into this.

One thing might help you?
I'm on a mac. I often have problems online with browsers. It's because ms is at the other end. I'll get odd things happening. I usually use Safari. Often times, Firefox.
I have used, but rarely, Opera, or Chrome.

Your avg frequency is being calculated based on the fuelups from 2-12-2016 to 3-25-2016, a span of about 43 days. That is seen as 1.4333 months with 4 fuelups. 4 divided by 1.433 is 2.79 fuelups, which is rounded to 3. As you add more fuelups, in a few months, your avg will begin to say 2 per month if you continue to have 2 per month. The avg will get closer to 2 as your fuelup count increases.

(It was calculating 4 so I made a change and it now calculates 3 per month, as reflected in my explanation above.)

Hehe.... got a good one for ya...
Just added another fuel up. Now it says once a week. Hehe
Lets just wait and see how it works out for a few months. Don't want to waste your time. Especially if all I need is more data input.

Question, when you buy a new car and start off, how are you supposed to account for this? It seems to me the first tank while technically NOT filled by me, came with the car and should be accounted for. Did I mess up? My total mileage seems to be low. HELP...

Depends on how you have selected to track your distance per tank.

Since you get the car with an unknown amount of fuel in it, you need to do an initial fill up to get a start point in which you know the tank is full. How you track this first fill on Fuelly depends on how you are tracking the tank distance.

By odometer, fill up the tank, and put an entry for it in your Fuelly log. This is to establish the start point, with full tank and initial odometer reading, for tracking your fuel economy. There won't be a fuel economy figure calculated for this fill.

By trip odometer, Just fill up and reset the trip meter. You put the first Fuelly entry in on the second fill up.

Car came w/ full tank of gas. Since I know that and the mileage, is it too late to add to current fuelly stats?

It may not have been completely full though, you can get much more, in some cases gallons of extra fuel in if you brim the tank. Unless you did this, then you first tank is going to seem worse as it will assume you used more fuel than you actually did. Your first fuel up should be the miles just driven, but measured using the fuel you just put in. I don't believe in "initial fills" or the like.

My total average on fuel ups is finally straightened out.
I can only rationalize it was lack of data. I know...I know... but don't argue with the computer....rationalize.
