Hi I'm looking for some info I recently done a road trip and so decided to do some partial fill ups to save having to stop to fill up and also to benefit from cheaper gas.
I thought I read that fuelly was able to calculate the MPG taking into account the partials after a full tank I put the partial tank details into the system. it doesn't appear to be the case looking at my stats its assumed all miles were from the last tank
You can only input the data once you've driven so many miles AND filled up with fuel, otherwise how do you know how much fuel you've used.
An example scenario, full tank, start trip. Decide to fill up again whether your tanks a quarter full, half full or even three quarters, it matter not. Brim the tank and make note of both miles driven, and fuel used. Input that data, fuelly does the rest. It's very simple. A partial fuel up is only if you don't fill the tank completely.
I just looked at your figures, they are way off. I see your best as 96 MPG in the Passat, with over 1300 on one tank, although that's been done in a Passat diesel, yours is gas so I'm assuming that's way off!
