Fjungman,
unfortunately I don't have a choice have to wait for the local dealer to receive them in Jordan

 

So far in 6,000 miles I have had one of the outer door trim strips come loose and a drives side door noise, not bad at all. Quality seems good.

 

im about to purchase a Yukon Hybrid soon. does anybody know how much it costs to get a full tank for it?

 

Depends on you gas prices.
Generally, if you don't wait for it to run out of gas, it will take about 24 gallons to fill it up.
Mine runs out right as the needle touches the "E". Don't trust the last 100 miles of range.
I usually fill up with about a 1/16 of a tank indicated.

 

fjungman, are you saying the Miles Remaining or Range is inacurate? I have been thinking that was much more accurate than a needle could be. Am I wrong? Isn't it all math?

 

They may be different in the Silverado, but the Tahoe is terribly non-linear in the bottom 1/2, with the bottom 1/4 being just 2 or 3 gallons. And "E" means "call a towtruck". I ran out a couple of times before I realized it was not me...

 

The needle may be flaky, but my experience is the data in the driver information center is pretty darn accurate. Fuel Used, Range to Empty, Avg MPG. Only time fuel used isn't all that accurate is right at the beginning with a full tank; 1st couple of gallons.

Also, all the Ford, Toyota and Honda Avg MPG calculations all seem to be about 2-3 mpg higher than actual in the cars I've driven (05/08 Escape Hybrid, 07 Highlander Hybrid, 10 Honda Insight)

 

I agree with the fact that the first half of a full tank goes down slower than the last, as far as needle indication goes, however the DIC seems to be vary accurate. I have had mine to 20KM left and it still ran. I wonder if the needle gas indication is ajustable, maybe a pentionometer? Pecofarads?

 

Most fuel level sensors are like a potentiometer; a wiper contact attached to the float arm sweeps over a series of resistor pads, and there's a calibrated transfer function that matches resistance readings to a fuel level (ohms). The raw signal gets processed in the cluster and is heavily filtered in software to give you a smooth needle reading. Old mechanical gauges (and the analog stock gauges in most older non-glass private planes) jump around more because they aren't filtered as heavily. You can't really adjust the response; that's programmed into the instrument cluster. FYI, if you want to get max range, pull the nozzle partway out and fill slowly after initial shutoff. You should get ~ 2 more gallons before you see fuel in the filler neck.
