I wanted to be honest and leave my lifetime milage alone (58.9mpg over 110,000 miles), however it would be nice to use Trip B as if the lifetime mpg was reset. Problem is, it resets. Not sure but it seems to go only to 2000 miles, then it resets to zero.

Yup :!:

That's the roll-over point for both trip A & B

Its your car. Reset or leave the LMPG to reflect what you want. Your "LMPG" or the cars.

The miles "roll over" but the mileage (mpg) continues to calculate.

I did exactly what you described and reset Trip B the moment I drove it away from the seller. I had a beautiful three year "Personal LMPG" until someone reset it during a recent dealer visit. :evil:

Now I just use the average from Trip A (reset on each tank of gas) from my first tank. That number has never been off by more than 0.1 mpg.

But back to the point, the mpg will continue to calculate for the duration on each trip meter until they are reset.

But IIRC its _average_ will only be of the previous 2000 miles.

Not true, even though the miles roll back to zero, the average MPG continues to calculate from the point of the original reset. It was something that Rick pointed out to me way back when I first got the car.

See Rick's comments here:

For the first year I was getting over 60mpg on my mostly freeway commute. Then my route changed and I dropped to the low 50's. My Trip B meter displayed my "Personal LMPG" of about 55mpg even though I hadn't had a tank average of over 55 for 18 months.

It's a nice way to keep track of a long term average as long as you can keep it from being reset!

Then I stand corrected :!:

Another "hidden quirk" of the Insight :!:
