Gas Tips!
Now I know this thread is pointless but I found it interesting. I appologize for the long thread in advance.....
Gas Pumping Tips from someone in the Petroleum pipeline business!!
I've been in petroleum pipeline business for about 31 years, currently working for the Kinder-Morgan Pipeline here in San Jose, CA. We deliver about 4 million gallons in a 24-hour period from the pipe line; one day it's diesel, the next day it's jet fuel and gasoline. We have 34 storage tanks here with a total capacity of 16,800,000 gallons. Here are some tricks to help you get your money's worth.
1. Fill up your car or truck in the morning when the temperature is still cool. Remember th at all service stations have their storage tanks buried below ground; and the colder the ground, the denser the gasoline. When it gets warmer gasoline expands, so if you'r e filling up in the afternoon or in the evening, what should be a gallon is not exactly a gallon. In the petroleum business, the specific gravity and temperature of the fuel (gasoline, diesel, jet fuel, ethanol and other petroleum products) are significant. Every truckload that we load is temperature-compensated so that the indicated gallonage is actually the amount pumped. A one-degree rise in temperature is a big deal for businesses, but service stations don't have temperature compensation at their pumps.
2. If a tanker truck is filling the station's tank at the time you want to buy gas, do not fill up; most likely dirt and sludge in the tank is being stirred up when gas is being d elivered, and you might be transferring that dirt from the bottom of their tank into your car's tank.
3. Fill up when your gas tank is half-full (or half-empty), because the more gas you have in your tank the less air there is and gasoline evaporates rapidly, especially when it's warm. (Gasoline storage tanks have an internal floating 'roof' membrane to act as a barrier between the gas and the atmosphere, thereby minimizing evaporation.)
4. If you look at the trigger you'll see that it has three delivery settings: slow, medium and high. When you're filling up do not squeeze the trigger of the nozzle to the high setting. You should be pumping at the slow setting, thereby minimizing vapors created while you are pumping. Ho ses at the pump are corrugated; the corrugations act as a return path for vapor recovery from gas that already has been metered. If you are pumping at the high setting , the agitated gasoline contains more vapor, which is being sucked back into the underground tank so you're getting less gas for your money.
Hope this will help ease your 'pain at the pump'.

I have no idea where this info came from but it was emailed to me. Anyone know if its true?

Re: (import_girl)
I know for a fact that you should never pump while a delivery is being made. The rest, I have no real experience of. I just know about the delivery because my mother is a district manage for an oil company.

Re: Gas Tips! (civic1234)
Sweet!! I always fill up in the morning. But, it's been in the 90's in the AM anyway but is better than 100's in the PM.
Maybe that's why I've averaged 37-40mpg without the AC on. But with the AC I'm getting 34-37mpg.
Great info!!

Re: (drkangel650)
ive always wondered about gas stations and there method of keeping the tanks full...
someone once told me that premium is clean fuel, and the "low grade" 89 er 87 is basically a mix of all the fuels but its got less octane and its dirty? i know SI owners dont have to worry about 87 or 89 fuel but just wondered.

Re: (i-spit-hotfire)
nope. cars are rated per use. an si has higher pressure and burns hotter, thus needing the 93 as it has a higher combustion rate. it takes more to ignite it. my EX runs worse on 93 than it does on regular.
also, all fuel is intermixed (excluding amoco ultimate sold via BP) whether in the pipelines or simply from being the same truck doing two shipments. It's all mixed so other than additives, no difference and even those are minimal.
Racetrack tends to have more debris and sometimes even water. other then them in hole in the wall places it doesnt matter.
And 89 octane isnt 8 anymore. before (and rarely still now) three tanks held three fuels. Now (again in all major stations) two regular and one hi-test. a blender mixes a 70/30 ratio mixing 'mid-grade' so it really isn't midgrade when you do the math.
mid grade is a waste. go low end, or if you require it, hi-test.
a few other things. All fuel stations have water in their tanks. ALL of them. there is a minimal amount they can get by with. ever see the long probes they use? it isnt just to measure the fuel to test sensors, but on the tip is a putty that turns red to detect water. Another reason not to pump during delivery, it stirs the water up.
And again, only BP sells amoco ultimate fuel which is the only fuel to not be mixed with any other.

This is the SECOND time i've gone into the 06 Civic forum in the 24 hours and I've seen you post some horrible argument based on no real factual information. Not only are you spamming with incorrect info that may be detrimental to some members, you offer no support otherwise, just one sentence and you're gone.
If you're going to say something that bold and stupid, at least defend WHY you think it's right.

Good tips, assuming they are correct. Time to submit more "gas guzzlers" ideas to Mythbusters! (It's a cool, educational show where they like to blow **** up. If you don't know about it or don't like it, you're unamerican.)

ok how about this...why do people get a higher octane??? because it takes more to burn...which means less prone for detonation in your precious high performance engine...so i honestly don't see how having a lower octane can benefit you more than a higher octane...unless you have a diesel engine which uses no spark plugs, thus having a lower octane doesn't seem so bad if you want to burn that fuel...go screw yourself.
i would also like to know what kind of information I'm giving that is incorrect buddy...i never really understood the reason everyone bashes on honda-tech...maybe it goes along with the immature fast and furious ricers out there who are so closed-minded they can't be open for debates...this is the only downfall that made me want to buy a different import car manufactured by something other than honda...but one test drive in the si and i was hooked. i just feel it's ridiculous that when i stand up for the guy getting bashed everyone bashes on me...who cares if someone buys expensive track wheels he probably won't take out tracking...i'm sure this is the post your talking about and screw you if you didn't like my analogy of having mugen wheels and tracking them as to having HIDs and driving fast at night as i've stated before on that post it was just an analogy to get you jackasses off his back from buying expensive wheels that probably won't see the track
what i meant was you can have wheels designed for the track even if you don't track the car....and you can have HIDs even if you even if you drive slow at night that you can see everything anyways.
