Wrong MPG Caclulation

[Deckard]

I'm not sure how the MPG calculation is being made, but this just doesn't seem to be right:

You put the wrong odometer reading on your last fuelup, #12.

[Deckard]

Why did that affect the June 2nd instead of the last one?

[freddie]

That is where the odometer that you entered into the last fuelup was slotted when the fuelups were reordered by odometer.

I have a miscalculated MPG on my last fuel up. Entered 237.2 on the odometer, but always get a calculation that omits the first number 2; so my calculated mpg is 3.2mpg. I've double checked the data entered and it's not me that's making the mistake.

[freddie]

You set your first fuelup at 200.2 miles.

Your second fuelup is set to 237.2 miles with 11.741 gallons.

So you are saying you traveled 37 miles on 11.741 gallons of gas.

37 / 11.741 = 3.15 (3.2) MPG

Thanks. I see what I did wrong now. Using tripmeter instead of odometer reading.

Looked at everything I could think of to fix. Please help. Keeps telling me that first fill up is not calculated. Worked until I changed trucks.
Thanks

You're tracking by Odometer. When doing so, the first fill-up is your starting point, so you won't see a MPG displayed because technically, it's unknown.
