I have had similar experience with my 2002 Sahara. The most I have ever been able to squeeze into the tank was 16.043 gallons, at which time I calculated my mileage to be 16.3 MPG (261 miles / 16.043 gals = 16.3 MPG) rounded of course. I love my Jeep, but why in the world the low fuel light comes on when there is between 4 to 5 gallons in the tank is a bit annoying to me. I hate that light to be on, but at least I know I'm not about to be walking. My '78 CJ-5 with the 5.0L V-8 only has a 13 Gallon tank, I could only imagine how often that light would be on (if it had one).

In most fuel injected vehicles, the fuel itself acts coolant for the fuel pump. This may be why the light reminds you to fill up with 4 gallons left in the tank.

1999 Jeep Wrangler When Fuel light comes on there is 16.3 gallons in the 19 gallon tank. I drove it until it ran out, the light came on and it went exactly 52.7 miles (according to the odometer*). The odometer (according to my portable GPS which claims accuracy of +/- .01%) registers one extra mile every 57.3 miles with stock setup. In other words, every time your odometer reads 57.3 miles, you really have only gone 56.3 miles. To calculate miles per gallon: odometer reading minus (odometer reading since last fill up devided by 57.3) This should take off somewhere between 3 and 5 miles per tank. Then do the corrected mileage devided by gallons filled.

I hope you'll take a moment to thank the mmeeldsode bureaucrats who actually mandated those efficiency standards, and maybe say an unkind word about the visionary capitalist heroes who have continually stonewalled such measures.I did some quick calculations, and if the 35MPG standard was in effect today (currently it is being phased in by 2020), the fleet would consume about 30% less fuel, saving about 6B barrels of oil a year (a number a bit short of the total reserves in ANWR). At today's prices, that's $600B a year we could be funneling into a second, third, and fourth Middle Eastern quagmire.The number is, of course, optimistic, since it doesn't account for non-transport uses of oil, or for fleet turnover. So call it $300B. Still plenty of money to launder to Halliburton through Iran.Remember, the auto industry screamed about how increased fuel standards would lead to the death of the auto industry and carnage on our highways. They resurrected the same zombie arguments against this round of increases, and I'm sure their warnings will prove just as misguided this time around. Now that the Prius is outselling the Excursion by 2 to 1, maybe the Big Three are thinking that these eco-weenie cars might not be such a bad idea.

Many customers don't trouble to examine their coverages, depending rather on which the representative informs them or a succinct summation that might be provided from the insurance QuotesChimp. And let us encounter it: the writing of an insurance plan isn't precisely Eliminated Against the Wind (even though it might appear equally as extended).
