Like the thread title says, I want to know about these tips for filling up at the pump that I keep seeing people post on Facebook, and whether these tips work, don't work, barely have any effect, more/actual tips for filling up at the pump, etc.

This is the text of what I keep seeing posted online

Facebook posted:

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

That is the entire text aside from the "Post this to 30 people, and those 30 people will...etc" stuff at the end. The TL;DR of it is:

1-Only buy gas in the morning, because when its colder, the gasoline will be more dense because of how cold it is.
2-A gas hose has 3 stages; Low, Middle, and High. You should pump on low to minimize the vapors that are created and sucked back into the storage tank when you pump.
3-If there is a Gasoline tanker pumping into the storage tanks when you get gas, don't fill up because the gas is getting stirred up and you may pick up some of the dirt that usually settles at the bottom.

So any knowledgeable goons know if these tips are actually true, and whether they make a significant impact or not? If you know of any other/actual tips for getting gas, or just things to lookout for when getting gas in general, share those too!

EDIT: poo poo, forgot the thread tag.

Shall we do it?

Tips 1 and 2 will save you pennies at most, even over the long term. Pretty sure tip 3 is legitimate, though.

As for tips at the pumps, I don't have any money-saving tips, but here's some general advice: Be nice to the cashier, because he or she probably hates this job. Use your debit or credit card to pay outside at the pump when you can, and if you decide to do that, then slow the gently caress down and follow the loving instructions on the screen. You shouldn't need help for something I've seen children do by themselves.

When the nozzle clicks off, stop pumping. If you keep going, you're probably going to spill down the side of your car or on yourself, and you'll look like an idiot and probably talk poo poo to the cashier, who had nothing to do at all with your stupidity. The nozzled clicked off for a reason.

Also, the cashier thinks you're an idiot for trying to get .00 cents and ending up with .01 or .02 and he or she is entirely justified in thinking so. Play it safe at .98 or .99 and don't tempt fate. You're not as good at this as you think you are.

Oh, and calm the gently caress down. Getting road rage at a gas station of all places just makes you look like a stupid loving rear end in a top hat. If you end up nose-to-nose with someone else's vehicle, then back up and let the other idiot have the spot, even if he was wrong and a jerk.

Had a long refutation ready to go, but then decided "Hey, let me Google that for you!"

So... Snopes.

Your best bet for saving gas is the usual - properly inflated tires, driving habits, maintained engine, etc.

Calm, relaxed...what could be more fulfilling?

I unscientifically agree with the Snopes article. These kinds of things come up all the time, but never made sense to me how it could save you anything worthwhile per fill-up. The last time I heard these tips come up on one of the morning "news" show's Money Saving Tips segment, it got me thinking about something else, though...

If you use premium gas in your car (I don't), what volume of the previous customer's gas type are you getting that's still in the hose? If I fill up with regular, then the guy behind me fills up with premium, is he getting 1/4 gallon of regular just to empty the hose before premium starts coming out? I'm not sure the volume of the average pump hose from nozzle to the valve that switches gas types. Is this how gas pumps work or am I off?

Not that it really matters because I rarely pay cash anymore, but it's really not that hard to land it at an even number. A lot of the Shell pumps (the white VPower branded ones) have really soft springs so you can control them very easily and it's a piece of cake to get whatever number you want. I've found that for example Chevron pumps tend to be much stiffer, so you have to be much more careful, but it's still not that difficult unless you have no fine motor control in your hands.

I'm slightly OCD so it does actually bother me not to have a round number, although to avoid topping off and spilling I usually go to within the closest 25 cent marker (xx.25, xx.50, xx.75, xx.00), but just off the top of my head in the past 10 years or so there's only been one or two times I've overshot, and I think only one of those was actually not being able to control the pump well enough, and the other was simply being in a hurry and not paying attention closely enough.

Anyway, there's two paragraphs of unnecessary sperging about gas pumps, but there's a tip that's just as useful as those in the OP - you can land the pump on an even number if you're not a gorilla.

And unless you pay with cash who gives a poo poo.

I have some great gas tips that will save you the same amount of money as those tips! Mine are rare secret tips that I only share in a low-cost pdf ebook that I have written. But since you are all friends, I, Noni, will share a handful of them at no cost.

Noni's Great Gas Pumping Tip Number 1:
A great tip that actually works is to get a can of compressed air and about 10 feet of semi-rigid tubing that you can connect to the can's nozzle. When you're almost done pumping gas, feed the tubing up the gas nozzle as far as it'll go, and then spray the air. You'll replace the gas in the pump hose with air and get about 2 free gallons of gasoline! The next guy in line will pay for air, so make sure it's one of those loving Obama-loving lieberals.

Noni's Great Gas Pumping Tip Number 2:
FACT: When you use a credit/debit card to buy gas at the pump, it only checks that you have about $50 available. This is why, when you have $20 in the bank and are trying to get gas, it'll reject your card even if you intended to only buy $10. That's oppression! You can take advantage of this socialist banking system by using pre-paid credit cards with balances of, say, $51. Then, go ahead and pump tons and tons of gas! Bring a 50-gallon barrel and fill it up. Fill up the boat! Have your wife move the cars so you can fill all six of them all up under one card. Wowzers! That's $600 in gas for only $51, or even cheaper if you bought the card using Bitcoins.

Noni's Great Gas Pumping Tip Number 3:
Did you know: Some people pump gas and then go inside the store while their nozzle is still sticking out of their dumb hybrid car? IT'S TRUE! Take advantage of these ignorant non-libertarians by carrying gas cans in your truck at all times. When the hippie motherfucker goes in to buy some hippie drink, run over there and fill your cans! That's what he gets for voting Democrat!

Noni's Great Gas Pumping Tip Number 4:
This is a super secret tip that I only share with my best friends, so LIKE ME ON FACEBOOK to hear this super-secret tip that can save you an average of $250 per month or even more!

Noni's Great Gas Pumping Tip Number 5:
Please buy my eBook to see this mega tip that can save you $900-1500 per week!

Noni's Great Gas Pumping Tip Number 6:
Please buy my eBook to see this ULTRA-SECRET tip that can NET you OVER $8000 EACH DAY in gas-based profits!

Noni's Great Gas Pumping Tip Number 7:
You'll have to read between the lines on this HYPER-tip. (Wink wink!) First of all, here's a random fact that is totally not related to anything: A gas tank wall is about 1 mm in thickness, but a large truck might be 5mm. That said, did you know that a sharp-pointed center punch can put a hole in 1 mm of steel in just one hammer swing? That's an interesting piece of knowledge! Furthermore, the bang of a center punch is not going to be nearly as suspicious as the sound of a drill. And even then, nobody ever bothers a guy who happens to be dressed like an officer for a costume party. Another unrelated fact: The same uniform store that city cops use doesn't ask for proof of your occupation! While I am sharing facts and not at all instructions: If you are weak or in a hurry, you might be interested to know that a powder-actuated tool, typically used for shooting nails into concrete, will fire straight through even 5mm metal so long as you first remove the nail head. Why, that can cause some things to leak and you might want to have a large pan, a funnel, and a big container handy for those leaks. Make sure you plug any leaks so you can "inspect" the hole week after week, again and again. Also battery cores sell for about $10.

Would have been a shame to blow it up.

10-4 come and exchange loads with me good buddy

Snarky poo poo replies aside, hot fuel is a real thing. There has been lawsuits about it, and it's a big deal when you are moving a lot of fuel. If you are really worried about it, don't buy fuel after they just filled the tanks, and wait for it to cool down. Never running around with less than half a tank could be a good thing, in case of power outage or bad weather, but it's also like running around playing a game, as you have X amount of dollars of fuel in your tank, and you are betting that fuel prices will go up, not down, plus if you pay on credit card, you can be ringing up fees if you don't pay it off at the end of the month. Another stupid thing I have seen is gas stations charging you a fee to use debt to buy fuel.

gently caress THAT noise.

Most of the time, you can shave pennies in better areas than worrying about hot fuel. Good energy saver tires, not hauling around your anime collection, emptying your trunk of dead hookers, etc etc. But then again, the best way to save money with cars or trucks is not to lease or buy one every four loving years because you are just pissing money away. Then again, I love getting trucks when fuel jumps and everybody is dumping their gas guzzlers and replacing it with a new Pruis, when they can't even figure out that $350 a month payment (and large insurance payment as well) is well above what they would have paid for fuel and insurance alone on their old truck or car.

Since the start of this year, I've spent $276.26 in fuel. Mind you, I drive a pickup with a 454 big block and a lead foot. Still, that's cheaper than most car payments for one month. My other truck...

A couple of times a week.
