Trip Odometer - it's not just a reset problem

[RickMachE]

I never reset Trip 2 from the day I bought the car. At 4,346 miles, it said my efficiency was 3.0 miles per kilowatt hour.

Today, I have 4,733 miles, and my efficiency is 2.5 miles.

Therefore, in the 387 miles I've driven since the last time I checked it, my efficiency is 0.87 miles per kilowatt hour.
Wow, I must really put the hammer down....

Wait, but my Trip 1 shows 2.5 which was reset at the same time as I read Trip 2.

In short, you can't trust anything but the odometer.

Yes, seems like a driving history reset zeros out Trip 1/2 efficiency metrics, so those values only reflect recent history not the correspond trip intervals. Is what it is, I guess, but not what I would have expected.

After my car got 3.6.2 today my Trip 1 and 2 read 0 mi/kwh efficiency. After a short drive, This Trip, Trip 1 (1,244 mi), and Trip 2 (6,886 mi) all read the same efficiency.

FWIW, I reset Trip 1 every 3 months assuming I would see seasonal variations...got me again Ford.

Yup, last night's update, makes sense. Ridiculous though. No way to see "lifetime" efficiency.

Where did the 0.87/kwh come from?

I did the math.

 

[MoonRiver]

I did the math.

I knew you did but how?

 

[MoonRiver]

Mile/kwh is miles driven divided by kwh used, just like mpg.

 

[RickMachE]

Miles divided by miles per kWh = kilowatts.

Subtract kilowatts for the lower number from the higher number, then divide that into the difference in miles.

 

[MoonRiver]

Since you never reset it so the average is the average over the entire time from day one to today.

 

[RickMachE]

That is what should be. But the update zeroed it out.
