GAS PRICES!

[tombogan03884]

Some of these tips while good in theory in alot of cases are unnecessary. At most of your high volume gas stations such as Walmart, Sams, Costco, Qt etc.... the tanks are never aloud to get low enough to have to worry about things being stirred up. The reasons are the same for the major oil companies if there is vapor in the tank the evaporation is slightly increased. Most of these high volume stations never let there tanks get that low.

Also fuel unloaded is only done so at these type of stations by gravity. There is not any outside force other than gravity controlling the pressure of the fuel. They don't get stirred near like people are thinking. There are also particulate filters at each of the pumps to keep solids from entering the vehicle. This is why you generally hear about water in fuel not particulate.

While filling up in the morning while ground temps. are low again is only going to be possibly noticed by those in Southern areas and then in the summer.  Those in northern climates will never know the difference. There are also steps taken to help the evaporation rates in summer time. They are indeed regulated but generally at the state level. This is one of the reasons people will notice a decrease in mpg. in the winter vs. the summer. As a result summer spec. gas usualy costs more.

While that may be true at depth, there is a lot of near to the surface piping that feeds the gas pumps at these large Mini Mart Stations, of which many are covered by thousands of sq. ft. of concrete with piping leading to all of the pumps just several inches below the surface. Out here in Arizona in the Summer it can easily reach 112 degrees plus during the heat of the day. The fuel in these pipes are several degrees hotter than the fuel in the storage tanks themselves. Hotter fuel is less dense.

This isn't going to matter in Fargo in January, but it will in Phoenix in July. It is pretty much common knowledge around here to gas up early in the morning.   Bill T.

It may well be true...

But, it's kinda like drinking lite beer while you're mowing through a meat lovers pizza for dinner.  The savings are probably as insignificant as the the calorie savings drinking terrible tasting beer.

Most days, I get dusted going home by a Prius doing about 90 mph.  I'm pretty sure my little car is getting better mileage than that asshole!

If it were not for the 50% Govt subsidy on "Hybrid" cars most Prius owners would be driving something less expensive, like maybe a Porsche 911.

How does this work? This is the first I've heard of it. 50% for the buyer or builder?  Bill T.

[tombogan03884]

For the builder, The actual cost of the average Hybrid is about  $80,000 the buyer pays in the range of $40,000.
The rest is made up of subsidies and out right loss to the manufacturer. No car manufacturer has ever broke even selling "green" cars. That's why GM dropped all it's hybrid models 10 years ago. That's why the "Smartcar" program in some large cities was finally scrapped by the last hold out San Fransisco last year. it cost far more than it was worth.

Not trying to argue the point but stir is not the right word to use for this. Yes there is pressure due to the volume of gas but it is also diminishing the moment you start to unload. If the point of entry of the fuel was at the bottom I would be more inclined to agree but it is dumped from the top. I have also watched multiiple videos of this process to see what the actual effects are and yes the lower the volume of product in the storage tank the greater the effect but unless the tank is near empty it is anything but dramatic.

On a side note my wife is lauging at me. I joined a gun site forum due to my interest and escape from work and the majority of my posts so far have been about work!  Go figure

Gasman, good to have you here.  Don't worry about the wife, just don't leave a link available so she can check up on you!   

Another informed opinion on any subject is welcome here!  Some may ruffle a feather or two but for the most part we're all like minded folks..

Welcome aboard!

Before environmentalists came along hydraulic mining was all done by gravity and pipe diameter reduction. They could generate enough water pressure to blast rock free from mountainsides. Remember "La Hood Mining" in the movie "Pale Rider"?

One foot of water at 62 degrees F = 0.433 PSI.   To find the PSI for any feet head, multiply the feet of head by 0.433.

100 ft is 43.3 psi
1000 ft is 433 psi

etc...
