I just filled my R with 18.5 gal of gas. The pump clicked at 17.75 and I squeezed the last bit in. The O manual says that the tank will hold 18 gal. Where did the extra go? In my minds eye I can see the filler neck It might hold what a gallon? Does anybody know it there is a vapor filter co connected to the neck, and if so can fuel get in there?<p>This was all caused by my inattentiveness. When I pulled into the gusstation (one word witth a yiddish accent) on fumes, the needle was buried below the left red with orange light on and no chime. The trip computer said I could go ---- far on my remaining fuel.. Any idea how much could have been left. Certainly no more than 1/2 a gallon.

Re: how low can you go? (CURT)

I thought every car has a overflow drain that will open after certain level of fuel. You probably left .5 Gallon spill next to the pump. Fuel tank is 18.5 IIRC. The highest I ever tanked was 17.5.

The capacity of 18 gal leaves room for vapor so the emissions system can work properly. Strictly by volume, the tank can hold more. You shouldn't overfill, it promotes smog due to fume release.

not all fuel pumps are calibrated the same. u pumped 18.5 might only have been 18. some places have been busted for over charging... i typically get 16 when the light first comes on

Re: how low can you go? (CURT)

Pumps are usually calibrated for a certain temperature (60deg in US). Since the gas is coming out at a higher temp you are actually getting less than what is metered during the summer months. <p>

The gas is stored in tanks under ground. Below ground temps are fairly consistent in all months SO it is pumped up and through the meter it still should be fairly cool. You definitely are getting what you pay for HOWEVER the pump may kick off at a lower amount as there is more vapor in YOUR tank.

Re: how low can you go? (kenhoeve)

MYTH: Temperature only causes tablespoons of difference in amount of fuel delivered.<p>FACT: A 25-gallon fill-up of 75 degree F gasoline equates to a loss of nearly one quart. The same fill-up at 90 degrees F equates to nearly a half gallon.<p> <A HREF="http://www.turndownhotfuel.com/myths.html" TARGET="_blank">http://www.turndownhotfuel.com/myths.html</A> <p> <br>Background on “Turn Down Hot Fuel” <br>In 2002, OOIDA staff began investigating the differences in mileages in diesel fuel from varying retailers, based on reports that truckers were getting different mileages from different fill-ups. It was in this investigation they discovered that temperature was making a difference in costs.<br>It was learned that some fuels are sold as high as 90 degrees F. An all-time high was sold to one driver at 118 degrees F.<br>OOIDA began taking its findings to the National Conference on Weights and Measures and lawmakers.<br>In 2006, some states began paying attention and set forth bills to address hot fuel.<br>Large consumers, such as the U.S. armed forces, have had temperature-adjusted purchase agreements for decades.<br>In 1990, the oil industry successfully lobbied for temperature-adjusted cold fuel in Canada.<br>In 2000, the IRS approved a new rule to close the loophole but the regulation was quietly withdrawn in 2001.<br>State officials in California and Texas are investigating how they can stop hot fuel overcharges.<br>

I don't dispute volumetric/temp change magnitude. You just don't get them with underground tanks that may vary 2-3* year round.

the tank is plastic ... it's volume-capacity expands a little after some time.
