Need help - my trip odometer was reset

[Keen4Green]

My car was in an accident and in the repair shop for about a week. During that time they had to take out the battery, reset the navi codes, etc, etc. I didn't think to look at where my odometer was, and this is what I use to input on Fuelly for fill ups. When I got my car back, I noticed my trip odometer was only 2.4 miles (probably representing a test drive).

So now I have about 1/4 tank remaining on my car and have no idea what my actual tank mileage will be when it's time fill up again and post here on Fuelly.

What should I do? Don't include this particularly tank and just post up the next one? Or try to estimate based on my commute, recent trips, etc?
