Forgot..snopes is still out on this one
Not driving like a possessed demon will save you ten times as much gas.
Best tip is to drain the gas left in the hose.
The moisture issue is a non-starter.
1. Only buy or fill up your car or truck in the early morning when the ground temperature is still cold......TRUE
2. When you’re filling up do not squeeze the trigger of the nozzle to a fast mode.........TRUE, but hardly a big difference.
3. One of the most important tips is to fill up when your gas tank is HALF FULL.......TRUE, but again, hardly a big difference.
4. If there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up.......TRUE........especially for fuel injector engines and especially DIESEL. But I’d be more worried about an explosion from a passing cigarette...........
I “Dollar Cost Average” my gasoline, which means I tank up on the same day each week, no matter what the level of gasoline is in my tank.
That way, I’m paying an “averaged” price each month and it doesn’t break the budget.
I do the same with investing. Each month I invest x-amount of dollars, but over the course of time, I’m paying an averaged cost on those stocks. Some months it’s higher, bust most months it’s lower or a wash, so I get more shares for my dollar over the long haul.
‘Tain’t Rocket Science. Don’t buy into the “we’re running out of gas” pap from fear-mongers. We aren’t.
These tips may have made sense in 1973, they don’t apply now.
1. Tanks are insulated. They stay within a few degrees of the temperature the fuel was delivered at. I.E. Hot gas in the ground tank stays hot.
2. Nozzles these days must deliver the proper amount and they do reclaim fumes. That said how much more fumes are created between slow and fast? I’d bet it’s a whole pennies worth. It’s not worth the extra five minutes you’re going to spend at the gas station.
3. The bit about fuel evaporating because your tank is half full is bunk. All vehicles built in the past 20 years have sealed fuel systems. No fuel is lost to evaporation. The reason storage tanks have a floating lid is that gasoline fumes are extremely flammable, by having the floating lid, they minimize explosion risk.
4. Getting gas while it’s being filled is not harmful. All fuel pumps have filters on them. They look like your car filter and they will stop any contaminant from getting into your tank. Do you think any gas station wants to pay for repairs on cars they just fouled up? Ever heard of it happening?
The ground temperature doesn’t vary much between morning and afternoon.
On the temperature part... the volumetric coefficient of thermal expansion for gasoline is about 1 part per thousand per degree Celsius (950*10^-6 for the nerds among us).
So... a 20 degree Fahrenheit change in ground temperature is about 11 degrees Celsius. And 11 parts per thousand on $3 gasoline saves you about 3.3 cents per gallon. That’s not a major savings but its not zero either.
3 * (989 / 1 000) = 2.96700
Bogus nonsense.
I thought the main reason the tanks are buried is because the temperature underground is stable? The only thing I can see that might be affected by temperature would be the pump itself.
Modern cars have a sealed vapor recovery system, the car burns the vapors. So I can’t see tank level having any affect either.
Much ado about nothing.
Grit your teeth, fill up and forget it.
It is all part of the American dream :)
I am so lucky now.. I have a bus that takes me anywhere I want to go in this city, and anytime I want before midnight, and I pay only the same as $20 per month.. Eat your heart out.
Whoever wrote this is full of the stupids.Ground temperature is very steady, and so is the fuel in the tank.
Waste of time to read further.
He said a jet aircraft (retired from airline) could be sitting on the tarmac, you could fill to full with fuel and after a length of time in hot temp., jet fuel would start pouring out.
I also received this email. One thing I don’t do, but I probably should, is keep a lot of gas in my tank. One of the things that pi**ed me off when my brand new Honda Prelude was stolen was that the thief had a full tank of gas on top of my new car. Out of fear, I keep about 1/4 to 1/2 tank of gas at all times.
The best tip is to put your gas card away for awhile. Find out where the cheapest gas is in your area and shop at that station, even if it means paying cash. Even if it means driving a few extra miles. We are creatures of habit, and tend to stop at the same station or two regardless of what happens to the price. We gripe because our station just went up to 3.57 - but yet ignore the station 3 blocks away at 3.32.
Case in point - the stations below are within a 2 mile area. If the price of gas is so bad why are the highest priced station not seeing a major drop in business? They should be left scratching their heads wondering where their customers are, and the cheaper stations should be pondering hiring some more help to handle their increased business.
3.57 Shell
3.51 Shell
3.51 Chevron
3.45 76
3.39 Texaco
3.32 Arco (2 blocks away from the 3.51 Chevron)
THe Republicans are going to lose lots of votes over these gas prices. (Don’t tell me who’s fault it is...the sheeple pin oil to Repubbies no matter what facts are out there)
in so doing, a little of the higher (or inversely lower) octane gas (in the hoses) should end up in your tank and might give you a bit of a boost (if higher octane)...
(remember reading this comment that your mileage may vary ;)
Below-ground temps do not vary that much, plus in the interest of their own business pump manufacturers use temperature-compensated pumps, or they’d lose money on cold days.
thereby minimizing the vapors that are created while you are pumping.
Cars since what, 1970 have vapor recovery systems.
The temp underground doesn’t vary much. This is mostly bullfeathers.
