It's not the car you drive, it's how you drive it.

Agreed. every fillup is normal. On track days, I reset it before the session sometimes to see my track session mpg. it's usually below 8mpg. hahahEvery fillup. It will never get reset in between fillups; that's blasphemy in the OCD world.

After every fill-up. So I can compare. Consistently find a ~1 mpg difference between OBD and miles traveled/ gallon filled.

Agreed with others for the most part. I leave #1 MPG alone and track my lifetime mileage. I reset #2 MPG at every fillup. I also reset average MPH at every fillup too.

MPG only gets reset before roadtrips. I don't care about mileage any other time, and also later on, I can look at my OBC and feel good about the good gas mileage since I know I don't get that during my normal commute. It makes me feel better about my gas mileage.
MPH never got reset on purpose. Probably only got reset when disconnecting the battery for various activities.

I reset every fill just in case something weird happens and my fuel is sucked away mysteriously. I will be able to tell from the OBC. Knowing what my approx mileage is between fill-ups is a good self check on my driving habits and what the engine is doing. I'd rather not go into gallons/trip everytime to figure it out.

Yep. I get about 100 miles per 1/4 tank... Give or take. More at the beginning than the end.I reset every fill just in case something weird happens and my fuel is sucked away mysteriously.
