Alright, I can get in my car and be driving around town, with a/c on and my fuel gauge will read 3/4 of a tank. A bit later after running some errands the gauge reads 1/2 full.

Then, I drive a bit further and the gauge will be back up to 3/4 and maybe a little over.

This happens a lot, even without the a/c on. Has anyone else experienced this issue?

 

I get it when I park on uneven surfaces. Like if I drive to a buddies house it will be on 3/4 then I park in their driveway which is on slope so when I get in it reads 1/2. Then after a little driving and the gas settles it goes back up to 3/4. It seems to take a little while for the gas gauge to catch up.

 

CH has a point here.

The fuel gauge can be influenced by hills, specifically when driving around town...not at highway speeds. If I remember correctly Sacramento has plenty in some areas. It could be that.

 

The gas float has to be on the right side of the tank, because when my car is tilted to the left, the gauge goes down. I don't know about front/back tilt yet, everything is flat around here.

Take a run up to the Champlain Lookout....definitely not flat getting there

 

I've the same issue sometime but don't bother me, gauge replaces itself quickly

 

Now will something like that throw off the econ number, or the milage range?

 

From the manual:

Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
• At the service station, the gas pump shuts off before
the gage reads full.
• It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to
fill the tank.
• The gage moves a little when you turn a corner or
speed up.
• The gage doesn’t go back to empty when you turn
off the ignition.

 

Naaaa.... too many tourists (and car thieves) up there at this time of year.... besides, it's a long climb, but it's not that steep; I've climbed it a few times on my bicycle.

Econ number, no; I don't think that what's left in the tank matters for that. Mileage range, definitely; it comes down with the gauge, but goes right back up when the gauge recovers.

hah hell one time i almost ran out of gas, car was sputtering cuz this exact thing happened...
