Instant MPG gauge and wth it means
#11
The OP doesn't have the info screen like you. He has a basic dash with the 2 line display like the one below.
Since the color info screen instand mpg goes from 0 to 30 mpg, maybe the 2 line display is the same. That would put each bar at 5 mpg increments. Just a guess. If that's the case, at 3 bars, you wouldn't know if it was 15 mpg or 19 mpg. Doesn't seem very useful at all to me.
Best I can figure, if you set it to 5 minutes, the bar updates every minute. The 10 minute setting updates a bar every 2 minutes, and the 30 minute setting updates a bar every 6 minutes. So the 5/10/30 minute interval is the time represented by all 5 bars. The "new" bar is added on the right and everything shifts to the left. When the truck is started, the green bars are from that driving cycle, and the grey bar are left over from the previous driving cycle.

lol... still trying to figure out the average MPG gizmo.
When I first started driving the truck, it was at 16.2 I believe. It was always a fixed number but, over approx. 1.5 years it kept dropping and whatever it dropped down to it was always a fixed/steady number. Few days ago it reached 14.9 so I reset it for the first time, now the numbers are fluctuating all over the place. Not sure what that's all about.
Sorry, didn't mean to hijack your thread.

I have the fancy one, and I never look at it. More interesting things in life.

Have the same setup... I don't even look at mine.

Since that is average MPG, it uses miles driven from the last time you reset to make a continuing average. The larger the numbers that are put in the equation, the less change there will be. When you first reset it though, it reverts to instant MPG, and fluctuates a lot. Every time you press the gas pedal down it will change, every time you let up it will change, until the miles get big enough that the gallons variable doesn't effect the outcome so much. Let it bounce back and forth for a thousand miles or so, and it will die down to the steady state again.....until you reset it.

Wow somebody else with the base cluster. I didnt know anyone on this forum had it other than me.
Yeah the gauge for instant MPG is useless. I only really look at it when it is windy, or to judge where to set the cruise control, to see if 100km/h or 110km/h makes a difference in a bar.
The average is pretty useless too. "15 liters per 100km" it will show, and when I calculate by hand it can be anywhere from 14.9 to 16 liters per 100km consumption. More or less just use DTE and the 2 trip odometers now.
