Default Question on the "Range" indicator on the dashboard...

While idling in the 7-11 parking lot for approximately 5 minutes, my range indicator went from 315 miles to 275. Is this normal? It went back up to around 298 when I starting driving it at normal speeds. I thought I was leaking gas, but didn't smell anything.


Thanks! :seeya

Yes, it is normal.... your range is constantly updated, and will change based on the current fuel usage versus speed(distance traveled vs. time). Since you are parked, speed and distance traveled are zero, but fuel is being used to keep engine running, the range will decrease until you start traveling again, where it will again continue to update based on those parameters. :cheers:

It does the same thing while you are stopped in traffic.

Of course it all depends on how you leave the 7-11 parking lot; my range indicator (and average mileage) usually drop till I hit highway speeds. :lol:

uh, the Range indicator has little to do with how far your really going to make it, tho... remember, it is dependant on the sender, and the sender has its own problems... such as the inability to tell you how much fuel you have left.

basically, it is neato... but rather useless.

I totally agree about it being useless, unfortunately. It has the potential to actually be helpful, especially on road trips, but it's not. First off, it's only as accurate as your fuel gauge... and I have yet to meet a fuel gauge that actually shows half a tank when the tank is half full. I think that is the biggest source of the inaccuracy.

As far as I've figured out, it multiplies your current average MPG times the number of gallons it thinks you have in the tank and that's how far you should be able to go. The only problem is, most of the time, it thinks you have more gas than you actually do, so it tells you that you can go farther than you actually can :(

Well Said :yesnod:

I've been debating on buying a new sending unit, but I am afread it will do the same thing after a short time, so that is 300.00 out the window.

Has anyone tried bending the float arm a little to compensate for the amount your gage is off?
