makes sense!!! Got this e-mail from my mom...


TIPS ON PUMPING GAS

I don't know what you guys are paying for gasoline.... but here in California we are paying up to $3.75 to $4.10 per gallon. My line of work is in petroleum for about 31 years now, so here are some tricks to get more of your money's worth for every gallon:


Here at the Kinder Morgan Pipeline where I work in San Jose , CA we deliver about 4 million gallons in a 24-hour period thru the pipeline.. One day is diesel the next day is jet fuel, and gasoline, regular and premium grades. We have 34-storage tanks here with a total capacity of 16,800,000 gallons.


Only buy or fill up your car or truck in the early morning when the ground temperature is still cold. Remember that all service stations have their storage tanks buried below ground. The colder the ground the more dense the gasoline, when it gets warmer gasoline expands, so buying in the afternoon or in the evening....your gallon is not exactly a gallon. In the petroleum business, the specific gravity and the temperature of the gasoline, diesel and jet fuel, ethanol and other petroleum products plays an important role.


A 1-degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps.


When you're filling up do not squeeze the trigger of the nozzle to a fast mode If you look you will see that the trigger has three (3) stages: low, middle, and high. You should be pumping on low mode, thereby minimizing the vapors that are cre ated while you are pumping. All hoses at the pump have a vapor return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapor. Those vapors are being sucked up and back into the underground storage tank so you're getting less worth for your money.


One of the most important tips is to fill up when your gas tank is HALF FULL. The reason for this is the more gas you have in your tank the less air occupying its empty space. Gasoline evaporates faster than you can imagine. Gasoline storage tanks have an internal floating roof. This roof serves as zero clearance between the gas and the atmosphere, so it minimizes the evaporation. Unlike service stations, here where I work, every truck that we load is temperature compensated so that every gal lon is actually the exact amount.


Another reminder, if there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up; most likely the gasoline is being stirred up as the gas is being delivered, and you might pick up some of the dirt that nor mally settles on the bottom.

To have an impact, we need to reach literally millions of gas buyers. It's really simple to do.


I'm sending this note to about thirty people. If each of you send it to at least ten more (30 x 10 = 300)...and those 300 send it to at least ten more (300 x 10 = 3,000) and so on, by the time the message reaches the sixth generation of people, we will have reached over THREE MILLION consumers !!!!!!! If those three million get excited and pass this on to ten friends each, then 30 million people will have been contacted!


If It goes one level further, you guessed it..... THREE HUNDRED MILLION PEOPLE!!!


Again, all you have to do is send this to 10 people. How long would it take?
 

Great post, although I'm not convinced in the fill up when only HALF FULL deal, so I'm looking for some additional discussion and opinion.
Here's why:

- If I fill up at 1/2 all the time, I am making more trips to the gas station than if I fill up at 1/8-1/4 full (which is likely a reasonable average fill up interval for many people).
- Even though filling up at 1/2 may not be a lot of extra trips to the station, I am still using more fuel to make these extra stops: my engine is running a little longer than it would otherwise because I have to make the turn into the station and drive to the pump, and then restart the vehicle and drive out of the station, often waiting for traffic to clear or a light to change.
- Also, I may not always pass by a gas station when I'm at or close to 1/2, so I may have to turn down another road, even if for a short distance, to get to the station.
- This extra running time is inefficient, and although it is a very small amount of running, it still uses up some fuel. Compare this with how much fuel can possibly evaporate into the small amount (8-10 gallons?) of average extra air space in the tank, over a time period of, say, a few days to maybe a week until I refuel at 1/8 tank or so?

Great tips.

This is true for older vehicles that do not have EVAP systems. New vehicles now have this EVAP system to control the loss of fuel vapours from the tank and lines

The pumps around here are set for an ambient temp of 15c. So if you fill up at 30c, you are getting the short end.
 
Interesting.

But really Blue,, Your Mom??? is telling you how to pump gas????

That's some funny sh!+ right there.

Thanks Mom for making me laugh. (You too Blue)

ops..ah..well she probably got the e-mail from someone and she just sends it out to everyone she knows....forward..you know...but she cares about moi!!!

X2 - it appears the author is from California which does have vapor recovery requirement at the pump but most other non-green states do not. If the pump nozzle has the spring loaded convolted covering around the nozzle it had vapor recovery. I'd guess many urban areas in Canada require vapor recovery.

1996 (OBD-II) and newer model year cars and light trucks are required to capture and store gasoline vapors. They're also required to turn the Check Engine Light on and inform the driver of a leak - which is often the cap. Prior to 1996 vehicles had vapor recovery, but weren't required to notify the driver when a leak was present.

IMO the 1/2 tank fill advise doesn't apply to vehicles with on board vapor recovery.

Depending on the saturation level of the canister and drive mode, >10% of the a/f mixture comes from the stored vapors in the charcoal canister so it's a good idea to have that Check Engine Light diagnosed when it comes on, just check your cap first.

That's sweet Blue.

Still got a chuckle out of it.

Probably cuz my ma wouldn't take the time to care. But,,,,, I ain't you and that could be the reason.

A bit of a black sheep here. (not surprized I'll bet)

Say Thanks and Hi to Mom.

Sincerly,
