Fuel Economy - Miles left until empty Confusion
So yesterday morning i jump in the truck head to work.. start out with 110 miles left until empty... about 1/4 mile down the road its magically jumps to 173 miles and then proceeds to drop like a rock the rest of the day.
This morning i get in with 69 miles to E... mile or two down the road it jumps to 120 miles to E....
I get that this can fluctuate but seriously... should i take the truck to the dealer or is this pretty normal?

Did you reset your avg mpg tracker? I believe it goes off that, and I could see it accurately fluctuating that much if there aren't many miles to average out your fuel usage... if i reset mine on the high way at speed, it goes up to 24mpg and if i do it in town in traffic, it will be less than 10 mpg and fluctuate quickly.

As explained in your manual:
MILES (km) TO E: This displays an estimate of approximately how far
you can drive with the fuel remaining in your tank under normal driving
conditions. Remember to turn the ignition off when refueling to allow this
feature to correctly detect the added fuel. Distance to empty is calculated
using a running average fuel economy, which is based on your recent
driving history of 500 miles (800 km). This value is not the same as the
average fuel economy display. The running average fuel economy is
re-initialized to a factory default value if the battery is disconnected.
You'll see wild fluctuations when you're parked at sharp angles (discussed numerous times on the forum) when the truck thinks it has MORE or LESS gas than it really does. And it doesn't react immediately, so you can be in a situation where you're angled in a driveway, start to drive, and then it reacts. The OP likely is parked at an angle where the tank seems more full than it really is, it reacts as he starts his drive showing a big number left, then realizes that's wrong as it's nice and level and corrects.

That's incorrect.
