Tips on filling the tank with gas

Cut and pasted from an email: I don't know what you guys are paying for gasoline.... but here in California we are also paying higher, up to $3.59 per gallon. 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 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. In slow mode you should be pumping on low speed, 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 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.

Here where I live we are paying about $3.15 The last time I was past a station. Thank you very much for this information. I had read about the filling up the tank in the morning but the rest is new to me. I will pass this on to other members of my family. I have to get my granddaughter to start filling up her tank when it gets half full instead of when it get down to a 1/4 or closer to empty than that. I'm going to copy this to give to my grandkids and their friends. Thank you very much and if you find or have an more tips please share them with us.

A good tip is if you only intend to drive a few miles and you need petrol then only put in enough to do your journey and not brim it to the top. This will save weight to the car thus the engine will have an easier life and will also ease up on the stress put on mechanical parts..... also if some little scum bag nicks your car they wont get to far with out much petrol in it......... tip 2. Whilst driving try not to use AC or the car radio as this also increses petrol consumption..... TIP 3. speed up a little more. On a recent motorway journey ( 70mph national limit ) I found that if i was to increase my speed up to and maintain 80mph (illegal I know but you will get away with that speed) my mmiles per gallon would increase according to the trip computer.

I dont know what your normal fuel rate is over in USA but the $3.59 you state as expensive is roughly £1.77 in uk money and I think we pay around £5.00 per gallon which equals $10.13. So you got it quite good compared to us. At the moment in the UK the average price of unleaded fuel per LITRE is about £1.10/£2.22 and im not sure how many litre equals a gallon.

We are blessed in comparison with the price in the UK. Next time I fill up I might remember to think about what a deal I'm getting in comparison -- but we're all getting ripped off.

You know, there's truth to these tips. However, what the email isn't telling you is how LITTLE these tips actually save you. In all honesty, there are better tips, including removing unnecessary stuff from your cars, stopping and starting gently, staying under 65 miles per hour, and keeping your cars tuned up. And you know what? There's inconvenience of having to stop for gas twice as often because you never go below a half a tank. Oh and most gas stations have filters to keep out junk the tanks have in them, and so do your cars.

You've brought up some excellent points, wildcat. I know driving slower saves gas, but on the open road i just can't control my urge to go fast! Thank you for your thoughts.

Thanks so much for sharing, this is definitely a big help to a lot of people, I'm sure. :D (I know I'm not saying that anyone else hasn't, but I thought I would post and give this post a bit of a boost while doing so. :) )

You can still find gas here in New Jersey at a couple of places for $2.99 a gallon. The average price seems to be about $3.03 here. The problem with New Jersey is that it is illegal to pump your own gas! This is something that I find to be ridiculous! We didn't know about this until we moved here a couple of years ago. Just another reason on our list of reasons we want to move away from New Jersey! The only place we can pump our own gas is on base. Gas on base is a few cents more expensive than those out in town though. It is irritating all around.

Love these tips and timely topic - never heard of most of them. We are paying the same for gas as you are and it's getting more than a little upsetting. As the weather gets hotter, these tips are going to mean a lot more too - may have to get up in the middle of the night around here to find temperatures under 80 degrees haha.. A good thing is the ground cools off really fast in the desert. whit

Hi Joyce thank you so much for this information, in future I will fill up in the mornins and always make sure tank is half full when I do rather than leaving it to get nearly empty. Hopefully that should help save something eh! Ellie :D

I knew about not filling up when there was a truck delivering gas but other than that this was all news to me. Interesting. Thanks for sharing and congrats at getting the ability to copy and paste.
