Does anyone know how to get the LMPG to update faster? I believe it is supposed to update once a minute. It seems to take longer. Is this because it only calculates lmpg when the idle stop is not on thus taking so long to update? :roll:

Double clicking the fcd button will only update the trip mpg, not the lifetime. In my personal experience I have found that patience is the best way to get the lifetime to update.

I find that switching displays immediately updates all my MPG displays. Of course, at 50k+ miles my LMPG isn't changing much anymore, but it used to...

update

Tim is correct. The LMPG is always updating, but the more total miles, the less the update will affect the displayed numeral, because the effect is just a tiny fraction of a numeral. For example, on a fresh tank of gas suppose you zero out a trip meter. Well EVERY 2 minutes you will see that mpg change, even drastically. As miles are travelled, it will visibly change less and less as it evens out and averages. Ultimately of course, a car with 90,000 miles will take a long time to improve lmpg from 70 to 70.2 even though it IS always internally updating...........Billy

lifetime mileage calculation

I was wondering if my LMPG is correct. Is it based strictly on miles travelled and the next full tank up? For example, I travelled a total of 612miles and my total gallons to fill the tank was 10.66 gallons. So 612/10.66=57.4mpg's. I am not sure if this is correct. At the time of fill up i had 44.3 LMPG. I heard that as you accumulate alot of miles the updater is slower but still updates. I only have 664 miles on the car and the LMPG now reads 45.4 LMPG. I am wondering if i am getting 45.4 LMPG or 57.4 LMPG.
Any help would be appreciated. :roll:

Your lifetime mileage (LMPG stands for Lifetime Miles Per Gallon) is the total number of miles driven by the car divided by the total number of gallons of gasoline burned. For the whole lifetime of the car, not just for one tank.

In your case, the lifetime mileage on your car is 664 miles and the LMPG is 45.4 mpg, while the tank mileage was 612 miles with a tank mileage of 57.4 mpg. You can track mileage for each tank by resetting one of your trip meters every time you fill up the tank (I use Trip A for each tank and Trip B for each time I leave the house).

BTW a 57.4 mpg tank is quite respectable for a CVT -- the average LMPG in the mileage database on the main site for CVT insights is about 52 mpg. As you continue to have more good tanks like that, your LMPG will continue to creep up. LMPG is usually low to start because a) dealers and test-drivers (especially test drivers) don't know (or don't care) how to drive the Insight efficiently, b) you (just like me) probably didn't know how to drive it efficiently either but will learn as you drive and so your mileage will tend to increase as you behave more efficiently, c) mileage improves after the car "breaks in" according to owner reports.

13.1 mpg!

cvtonly,

from your numbers, the car had 52 miles and a lifetime mpg of only 13.1 when you picked it up.

This is entirely possible, dealerships move the cars around the lot and probaly idle them a lot, too. Then there are madmen test-driving them.

You can reset the lifetime mpg to clear that off your record.
