Question

Is it true that you get more gas with temperature low whil early in the morning?

Answer 1

I'm sceptically, the theory is good however I've been underground and the temp of the earth doesn't change drastically like on the surface.

Answer 2

No, no, no, no.  This is a myth perpetuated by idiots in the media who don't understand chemistry and physics.

Gasoline is stored in underground tanks where the temperature rarely varies more than a tenth of one degree during the course of a day.  Gasoline is drawn out of the tanks by pumps and travels to your car in less than 5 seconds after leaving the ground.  There is no temperature dependent benefit to buying gasoline at any particular time of the day.

Beyond this rumor, gasoline has energy based on the number of molecules, not the volume of gasoline.  If your car's fuel is very warm or very cold, your engine's computer will adjust fuel flow to compensate for the varying density of product.  As gasoline warms up, it will have less energy per given volume and your car will inject more with each cycle.  When it cools down, your car will inject less gasoline, since it's getting the energy it needs from a lower volume.

Answer 3

It may or may not be.   Depends on the temperature of the fuel in the tank and the ambient air temperature.      Gasoline is slightly denser at lower temperatures,  like most liquids,  and most retail level pumps in the US  are not temperature compensated.

Generally,  by filling in the morning,  any expansion due to heat occurs during the day as you drive.

Answer 4

no its all about the beans

Answer 5

No. And I wish people would stop saying it is. It makes them sound like idiots. There are many people who fancy themselves chemical engineers who can rattle off made-up facts like this with little or no verifiable proof, yet they cannot even figure out what clothes match in the morning. The result is a lame internet legend and a costly requirement that every pump at every fuel station in the country be emblazoned with a sticker that explains this bull in several languages.

Answer 6

yes

here in arizona we pay for gas we don't use because it is so hot the gas expands and evaporates in the tank
