Why Two MPG Gauges ?

[69Sting]

Curious if any here knows why there are two MPG gauges when they both reset when you press O.K.?
I thought each one would be a different 'trip' MPG monitor. So if you were doing a long drive you could figure out each fuel tank as well as overall on the 1,400 mile trip. But every time I reset one the other resets. Hoping it is a 'user' issue and not some silly programming flaw that wasn't caught.

there are two trip meters, A & B you can use as you described. toggle to trip meter then left or right arrow on steering wheel to select.

Yep, I figured that out. But when I press OK to reset A then toggle to B, B is reset too. This is MPG screen where it tells your ave MPG and Current MPG with the fuel pump in the middle. I think there is another screen that has just trip info.

No idea, but it isn't exclusive to the RAMs. Every vehicle they've made in recent years has the same 2-screen MPG page setup, with no real clear reason why.

The Fuel Economy screens aren't Trip A and Trip B, there are two screens, and the second one simply ads the instant mpg display, the first one does not show it. If you switch to the Trip Meter, you'll find that Trip A and Trip B both keep their own average fuel economy records separate from the Fuel Economy Screen. I think the Trip Screen is #5 in the TFT display (between the gauges), and I think Fuel Economy is #4?

Thank you riccnick....

Thanks, I had this same question and wasnt making the connection that instant mpg did not show on both displays.

I looked yesterday, and both screens on my truck appear to show the instant fuel economy. I'll have to pay more attention on my commute home tonight.
