With 50 miles trip after top-off the gas tank and fuel gauge still indicated almost full, it suddenly dropped to less half tank after another 10-15 miles drive. Even though stopped and restarted car several times, the gauge still shows less half tank gas while the trip mile just reached 65 miles. Is it malfuction for the gas tank sensor or too much air in the gas tank. Should I go to deal for the check as I just got the car 4 weeks ago. Some comment?

The "low fuel" light seems to come on pretty early, but I'm not eager to find out the hard way how much gas is actually left in the tank....what are your experiences?

If memory serves, and at my age it often doesn't, when the low fuel light went on, we filled up and found that there was about 2 U.S. Gals. plus a bit left. Of course we were not at the station where we usually fill up so there will be some small variance. nmk |

Last night I filled up the tank after driving with the light on for about 30 miles. I only managed to put 14.50 galleons. This meant that there was 3.7 gallons in the tank when the light came on. HOWEVER, the gas icon remained on and when I re started the car this morning, the icon was still lit!!!  Darth Vader Grey, etc, etc.

Replying to: vbbuilt (Feb 26, 2007 5:50 am)  Truth to tell, I really have little to complain about, save for the two main items. Poor shifting pattern and gas mileage. I hope that both will be addressed when I have my 5k checkup. However, as you claim to be a "Technical Expert", (see your remark in an earlier posting), If I drive in auto and use cruise control more often than not, how does "Fuzzy Logic" enter into this? Darth Vader Grey etc. etc.
