What do you mean by "You"?

I reset mine every fillup.

I sometimes do it at fill up and I sometimes will change it if I drive the interstate to work at 75 and reset on the way home on a 55mph side road or sometimes if I'm driving in city traffic. The differences you see can vary greatly.

Mine gets reset only when the car battery is replaced. LOL. On a serious note, I did reset it one time in the past 3 years (I bought my car in 2010).

i usually reset it before road trips where i want to compare highway MPG to city driving.

but if i'm not traveling, i typically never reset it. i know the car gets roughly 20mpg in everyday driving.

I do every tank or if I'm doing a long trip I reset it before the trip and let it run for however many tanks the trip takes.

I reset once a month, my ZHP was getting 19 average with my lead foot.

I only reset on road trips... that's the only time I care about gas mileage.... my foot's too heavy other times.

Every fillup. It will never get reset in between fillups; that's blasphemy in the OCD world. :shifty

Funny, I read 'how' do you reset.... I rarely do mine. Maybe before a trip.

I usually calculate MPG based on mileage and how many gallons I put in the tank, so I dont really use the MPG. Every once in awhile i will reset it before a road trip. Heading to tahoe this weekend so probably will again. :)

Unless you do maintenance that requires a battery disconnect.

I haven't had to disconnect my battery since I replaced it almost 3 years ago. :shifty

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. hahah

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 get about that as well. I drive a 60/40 mix of highway/city driving.

Every fill up for me as well

Didn't know there were two mpg readings, or am I misunderstanding you?

When you're equipped with OEM Nav...you get two separate resetable fuel consumption readings.

Yes, I never reset one of them, and I'll reset the other for a trip once in a blue moon.

I cant remember the last I reset it, but since the topic is brought up, i probably will on my trip down to VA next Friday...

As a mild hypermiler, I'm pretty precise about my fuel consumption - I fill up every Friday after work regardless of how much or little I've driven that week, I reset MPG and MPH at every fillup, and I manually calculate my fuel economy in a logbook. Using the OBC is redundant and less accurate than my logbook, but the regular resets allow me to monitor any car-health issues affecting economy before I get to the end of the week. Also, the regular resets keep the meter 'lively' and responsive to changes in driving habits, which helps me encourage myself to drive economically.

Or the "A OK" to rip it to 6,800 which I often do! :D

I don't think I have ever reset the mpg on the OBC. I like to get an idea of how the overall mileage is trending. I was having battery issues on my X5d and the OBC was resetting itself at random times. I was more bothered about having the data reset than the battery issue itself. Must be my engineer tendencies...

There's an overall mileage in the secret OBC, menu 5.0, if I needed to know lifetime mileage.

That would explain it lol
