Recieved this in an email at work and wanted to share....

Tips on pumping gas.


I don't know what you guys are paying for gasoline.. but here in California we are also paying higher, up to $3.50 per gallon.***now close to 4 actually here in SoCal*** But 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 to tal 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 exp ands, 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. In slow mode you should be pumping on low speed, thereby minimizing the vapo rs that are created while you are pumping. All hoses at the pump have a vapor return. If you are pumping on the fast rate, some other 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 or HALF EMPTY. 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 gallon 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 normally settles on the bottom. Hope this will help you get the most value for your money.

good tips, i'm not sure how much gas this will save you

But a good tip going around here is that for every 5mph over 60 your losing about 20 cents per gallon, so there is a good reason not to speed.

Here's a tip that will save you more than all the tips above. Don't accelerate fast and also, drive slow. I understand that those tips given may save you a couple cents per fill up but changing your driving habits can save you a couple bucks per fill up.

This was on a couple other forums I am on. He said the temperature thing won't effect you. The gas is far enough in the ground in most cases to have no effect. Not sure if this is true or not. Just what I read.

A 'No fat chicks' decal on your car will greatly improve fuel economy, but may result in external damage and is therefor recommended for beaters only.

Jeep's gotten hella expense to drive around now... It's turned into a cruise-day/bad weather/recreational vehicle now. Gotta toodle 'round town in the wife's Focus. Funny thing is that because I'm so used to *****-footing around in my Jp and trying to get every last inch from every ounce of fuel, that I get better mileage in the Focus than she does biglaugh.gif

Before I put my bigger tires on (no gears yet), I was getting damn good mileage in the Jp, being what it was. 300 round town, 380 on the freeway... 18 gallon tank. Full tune-up, intake, TB spacer, full exhaust... all of them tied together to free up some power and make things more efficient. If you're not using that extra power all the time, they do tend to increase efficiency.

Moral - use the efficiency excuse to justify that new supercharger, exhaust, or intake icon_smile.gif

^^ I've noticed this as well... especially in the Focus. Seems to do better up around 75-80. Dunno how or why, but it'd be interesting to find out.

exactly like cyber knight said, lightening the weight of your car, thats one of the best things i think you can do, went from 200 miles a tank to 250 miles. same driving conditions,and driving style, from work and back. when i cleaned out all the junk from my car, could get more if i took out the system. but thats a no no icon_smile.gif

aerodynamics plays a role too, after covering those big holes i had in my bumper from no fogs and after i noticed slightly better fuel mileage.

You lose. If you're going to buy something might as well make it the Tessila Roadster.

HAHAHA, you might want to switch the direction of the little "less than" sign in the middle.

I also wasn't talking about cost, I was talking about gas mileage. But lets talk cost. I currently have a vehicle that gets 30mpg and I can drive it any time of the year (rain, snow, etc). A bike would get better gas mileage, say 45mpg. But I would have to buy one at a cost of around $4000. Driving 12,000 miles a year at a gas cost of $5/gallon, I would have to drive the bike for 6 years before my gas savings equaled the price I would spend on the bike. This is also assuming the bike is driven year round in the snow, rain, and any other bad weather. Do this comparison with the Tesla and it's even worse. Final conclusion, buying a new vehicle for the sole purpose of saving gas isn't too smart unless your vehicle gets around 10mpg or you're already looking for a new vehicle for other reasons.

Ooooooookay.

"You lose. If you're going to buy something might as well make it the Tessila Roadster. "

Perhaps that misled me. Although I do agree that buying a new vehicle to save gas makes no sense, unless it reduces your payment at the same time. Jeep gets 10.7mpg pretty much across the board, and I'm perfectly happy with it still, even with it taking premium. Wife's got the fuel-saver icon_smile.gif

Man I looked up the Tesla. That's freaking impressive for an electric car! 0-60 in 3.9 seconds. That's amazing. It does only .2 seconds slower than a 911 turbo in the 0-60.

Im guessing your pickup truck or whatever it is your driving doesn't change up until your above 60.. sumthing or the over drive doesn't engage above.. whatever

but you would be saving alot doing 50-55 if you can bare to.

In the uk its over �5 = $10+
Ways to save Petrol/Gasoline.
relaxed acceleration and deceleration i say drive like an old man but Its mostly just good driving habbits of forward thinking... like how long before those traffic lights change whats the lowest average speed i could get away with before they change to green... stuff like that.
If everyones up each others bumpers/fenders just cruise up slowly lightly braking maybe its easy stuff.

also turn off all an any un-nessasarry electrics stereo lights the works.
if you have a manual transmission when your up to about 30mph you can probibly get away with 5th gear i know i do i allways short shift. i get about 600km per tank of my kia rio an thats all of about 35 litres. doing about 65mph
you can save a huge ammount of energy that would be lost in drag by slowing down just 10mph like doing that could easily save you 10mpg which realy adds up and the time your losing getting to your destination is minimal.

A final thought.

I think it takes more balls to stick to a speed at or below the speed limit than to follow everyone one else in burning up there fule and making those trips to the gas station a regulare occourance.

Also all you motor bike fans on my last trip to the stats i was driving my dads ford ranger towing a 2000lbs trailer with a classic car on the back just crusing at 50-55mph and the same motor bike passed me 3 times over a 50 mille distance and i never stoped. but im guessing long trips on a bike make your bum go numb or sumting.

Ohh and final tip get a 4cylinder car or 3 cylinder car if you like you save loads compared to a v8 or v6
if you can afford it and like having fun get one of these babys http://www.dragtimes.com/images/11613-2006-Ariel-Atom.jpg

These tips are either incorrect, or you'll save so little fuel that you'll probably waste more just trying to use the tips....

http://www.snopes.com/inboxer/household/gastips.asp

The follow-up suggestions are good, though. Less weight is always a good idea, as well as more gradual acceleration, etc.

Or stop worrying about gas and ENJOY DRIVING. I don't even look at prices, I never really have. And I'll always need gas no matter what the cost, especially living in the sticks. I pull up and pump the best **** they have and be on my way. biglaugh.gif

I do this too, but it also helps that I get paid mileage to and fro work, so that more than covers for my gas and few minor repairs.

This man speaks the truth. I feel the same way. I drive pretty heave footed. I have a good time driving around. I don't let gas prices stop me. I got a simple weekend second job. Easily pays for that. And then I can actually enjoy myself and driving.

You're wrong, but ok.

OD engages at about 45MPH in my truck, the truck does better @ 75MPH then at 50, 55, 60, or 65. Like I said.

Why? Because the transmission isn't constantly hunting between 3rd and OD. It has enough momentum to sustain wind-gusts, or slight inclines to stay in OD.

It's a 3-speed with overdrive automatic in an SUV, btw.

Yeah, I haven't ***** once, and I get pretty bad gas mileage as everyone keeps telling me, I think its excellent gas mileage for a truck that can haul 8 people, and 10,000lbs comfortably.

lower speeds, means less wind resistance, meaning engine works less, meaning lower engine revs... You want me to draw you a picture!

also using "The best ****" at the gas pumps Doesn't mean its the best for your engine. it should tell you in the manual for your car but i read in the manual for my mitsubishi that any petrol*gas* thats more than 10% ethanol has a detrimental affect on engine life.
Ethanol is just alcohol and methanol which makes Ethanol. They only add methanol to it so people don't drink it.
some times added to 87octane fule just to bump it up to 91 octane.

I tried to justify this buy, but even if I bought a bike for 3 G's I wouldn't be able to drive it everyday b/c of weather and I wouldn't save that much for years.

All I know is I'm glad I didn't get a Caprice like I wanted.. my big v6 Park Ave is bad enough. Oh well, the tips I get from delivering pizzas pay for my gas x2 usually.

I tried some stuff I read from a hypermiling article one time.. but it just gave me an ulcer and took the fun out of driving. I try to drive modestly, but don't coast from 55 down to 0 just to save a few cents.

Plus having subs and a full air ride setup in the trunk can't be very good for mileage, either, lol.

No. Like I said before, lower engine speeds come from holding OD (Overdrive) which isn't possible at speed less than 70 in my truck, it hunts between 3rd and Overdrive (that means switches back and forth) which makes it inefficient.

Do you want me to draw YOU a picture?

My truck is a big square, its not aerodynamic even when its sitting still so wind resistance is always bad.

We plugged my bluetooth OBDII adapter into it and on my 500 mile trip to maine recently I drove the truck at different speeds for 10 or more miles (sustained) and monitored fuel consumption on my laptop. It was LESS (note, that less means not as much) when I set the cruise @ 75mph.

Seriously, it makes no sense, lol... But I'm right there with ya DJ - Jp gets much better mpg at 75 than it does at some piddly 55. So does the Focus, but that's gotta be up around 80. Still gets better mpg than down in the fifties.

No. Like I said before, lower engine speeds come from holding OD (Overdrive) which isn't possible at speed less than 70 in my truck, it hunts between 3rd and Overdrive (that means switches back and forth) which makes it inefficient.

Do you want me to draw YOU a picture?

My truck is a big square, its not aerodynamic even when its sitting still so wind resistance is always bad.

We plugged my bluetooth OBDII adapter into it and on my 500 mile trip to maine recently I drove the truck at different speeds for 10 or more miles (sustained) and monitored fuel consumption on my laptop. It was LESS (note, that less means not as much) when I set the cruise @ 75mph.


I was going by what you said that the OD engages at 45mph so there fore if you could keep a speed of 55mph you would be saving gas.

judging by the 3 speed ford ranger i have which also has overdrive i can cruise at 50 doing around 2000rpm or cruise at 70mph doing well over 3200 rpm its a V6

from my calculations even if you traveled 100 miles doing each to make a comparison you would use more fule at 70mph cause of the engine revs and thats not to mention the higher forces it has to cope with as wind resistance.

at 50mph doing 100miles it would take 2 hours.
at 70mph doing 100 miles it would take 1.43mins <I rounded it up
50 mile an hour doing 2000 revs for 2 hours 240,000
70 mile an hour doing 3200 revs for 1.43mins 274,560

maybe your truck is different Im sure.

Also on your Test were you drafting other vehicles because that greatly decreases drag being in some ones slip stream.

ooh and also as others have mentioned the liquid in the underground tanks stays at 15degrees C and the pumps are calibrated for it so chances of getting more gas than you pay for is minimal.

Like i've said like 5 times, my truck doesn't hold OD @ 55mph.

ONCE AGAIN TO REITERATE: My Truck doesn't hold OD @ 55mph. It hunts (switches, for those who don't understand the concept of a transmission hunting gears) between the 2 as wind resistance and inclines come into play.

I was not drafting any vehicles, or dealing with any great upward or downward slopes, it was about 3am, no other cars, and about 3/4 tank of fuel.

75mph for me is about 1,500RPM, if that. My truck has a very low engine speed @ cruise levels.

This is a V8.


My truck also does better on gas while towing over 65mph. I drove for about 200 miles @ 35-45mph (depending on the old people that got in the way on the back roads going 25mph in a 50mph, cant pass with a loaded trailer for safety reasons). and it was probably the worst gas mileage I'd ever gotten towing like this. Return trip we took the highway and i hit the cruise @ 70mph and it doubled (at least) the gas mileage. I was towing 6000lbs in a tandem axle box trailer, a little taller than my truck.

Im guessing your pickup truck or whatever it is your driving doesn't change up until your above 60.. sumthing or the over drive doesn't engage above.. whatever

but you would be saving alot doing 50-55 if you can bare to.


You're wrong, but ok.

OD engages at about 45MPH in my truck, the truck does better @ 75MPH then at 50, 55, 60, or 65. Like I said.

Why? Because the transmission isn't constantly hunting between 3rd and OD. It has enough momentum to sustain wind-gusts, or slight inclines to stay in OD.

It's a 3-speed with overdrive automatic in an SUV, btw.


your wrong.
lower speeds, means less wind resistance, meaning engine works less, meaning lower engine revs... You want me to draw you a picture!

also using "The best ****" at the gas pumps Doesn't mean its the best for your engine. it should tell you in the manual for your car but i read in the manual for my mitsubishi that any petrol*gas* thats more than 10% ethanol has a detrimental affect on engine life.
Ethanol is just alcohol and methanol which makes Ethanol. They only add methanol to it so people don't drink it.
some times added to 87octane fule just to bump it up to 91 octane.

Is it really that important who is right or who is wrong....
Come on kids just drop it..

Back on topic- i have changed my driving style drastically. The way i was driving i was wasting about $25-30 a day. I'm a FT student and work 2 PT jobs so money is tight.
Now i put $20 a day. It hurts my wallet like hell but i do drive alot. In 7 months of having my truck, i've put 19k miles icon_eek.gif

so is it actually true then that breathing mods DO help mileage and not just hurt it more?

I could see it actually helping mileage. Don't know if that is true though. Would just make sense that it would.

I never understood the concept that more air = better gas mileage.

Anytime you add more air, you're engine sucks more fuel. (Hence how a carburetor or throttle body works).

I haven't discussed this with anyone who had a really good answer other than some made up BS. I could be wrong, but I've never seen it improve with after market intakes, turbos, superchargers, etc.. etc..

The only reason i could ever see an intake helping in any way is that the air would be able to help the fuel burn more efficiently and more complete. Thus using all the gasd to maximum potential. Don't flame or bash as i see this as speculation. And it's only an itake that would help. A turbo or SC would in NO way help rather it would hinder this aspect.

My exhaust helped....I'm thinking my Intake and header might have hurt my gas milage though...

Causing extra air into the engine couldn't really help in gas mileage. It could be true that the extra air will allow the fuel to burn better like Robbie said. Also, the extra air is going to take more gas in as well. This is why there's a power increase w/ a better intake, more air/fuel mixture = more power (same thing w/ a supercharger or turbo).

Adding headers/exhaust will most likely help (very little) in the mileage due to reducing the restriction on the exhaust. If the engine doesn't have to work as hard to exhaust the gas then that takes off on the engine load = better mpg.

maybe engine load is the key here... it'll be easier for it to both take in air and also send it out...

Right, but taking in more air also means taking in more gas. This will reduce the mpg of the vehicle. As a rule of thumb, power and gas mileage are inversely related.

its the fact that the colder air is denser carrying more oxygen so better combustion to fuel ratio and headers and exhaust decreas back pressure allowing better use of gas as well. These items do help yes.
