Its that time again. Gas prices are raising!, Where do you live and what are the prices? Options

One thing is really interesting (for me). Information of octane number.

EU use 95,98 and 100 octane gas, but I see US has 87,89 and 91 octane gas... For same engines! Or I missed something?

Yup - you're missing the simple answer. US and Europe measure Octane slightly differently. We use RON, you use MON. MON is slightly more consistant I think.

Mr_E thank you, you hit the spot! FYI see this

Measurement methods

The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel through a specific test engine with a variable compression ratio under controlled conditions, and comparing these results with those for mixtures of isooctane and n-heptane.

There is another type of octane rating, called Motor Octane Number (MON), which is a better measure of how the fuel behaves when under load. MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, a higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON. Normally fuel specifications require both a minimum RON and a minimum MON.

In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "normal" gasoline in the US and Canada, would be 91 in Europe.

The octane rating may also be a "trade name", with the actual figure being higher than the nominal rating.

It is possible for a fuel to have a RON greater than 100, because isooctane is not the most knock-resistant substance available. Racing fuels, straight ethanol, Avgas and liquified petroleum gas (LPG) typically have octane ratings of 110 or significantly higher. Typical "octane booster" additives include tetra-ethyl lead and toluene. Tetra-ethyl lead is easily decomposed to its component radicals, which react with the radicals from the fuel and oxygen that would start the combustion, thereby delaying ignition.

BTW: I was bit confused because of one part of your answer "We use RON, you use MON" couse I'm from Europe , but now is everithig clear

This was just suppose to be a compairing local prices thing, not an arguement over who pays more, and who shouldnt complain. You are all trying to get this thread closed.

You are right... We need to realize that we have chance to get knowledge of something. For example:

- which price you must pay for fuel around the world
- how is measured octan number (and that there is difference between US and EU)
- differents between units
- practise in English language

That's why I'm here almost every day. These forums are perfect place for this...

p.s.: I hope this post will not be ridiculous for you

[97sccelica]

just filled up tonight in Van Nuys, CA at a chevron station

$3.25 a gallon for 91 octane

at least my wrx gets 20+ mpg every tank, its usually about 23mpg

Whoops. Sorry man. I just assumed and shouldn't have.

[Predator]

6.04 a gallon here, but it's the swedish governements fault, first we've got massive amounts of different taxes plus VAT on the gas and VAT on the fu***** taxes

[Cutrara]

Gas was so awesome when it was like $15-$20 to fill up your tank. Now it costs me at least $35.

Springdale Sheetz, 87 Octane- $2.95/gallon

[axelrduvirage]

1.209$CDN per litre for Octane 87 as of 2 pm today...do the math I'm too depressed to retain numbers.

[dstrbcelica]

it's 2.79 for 87 octane. ::sigh:: my jeep gets 16.9 miles per gallon. damn i miss my celica.

I realize you guys over in the UK pay a lot for gas (pretty much everywhere but the states), but I have something to tell you. WE IN THE STATES ARE NOT USED TO PAYING THIS MUCH!!! Stop griping to us about our complaining when we're used to a certain quality of life, and when gas prices take a 50% hike in a matter of a month, that changes what we're used to. You guys overseas are used to paying the high prices, and those high prices are largely in reason to the amount of taxes on them. That said,

The oil companies are feeling us out to see what we're willing to pay. There's absolutely no valid reason for how our gas prices have been raising recently. I've seen plenty of excuses thrown out, but no real reasons. I personally believe we need federal regulation of the petroleum industry here in the states to keep this incessant price gouging going. It's already being looked at in the natural gas sector, so hopefully it's only a matter of time before it hits the oil compaines too. Just give it a few more weeks until the oil companies start posting their rather large profits again and the government will start turning an eye towards them and they'll back off like what happened last fall.

ok lets all go back to ECONOMICS 101...

gas just like anyother world commodity has a DEMAND and a SUPPLY

now with prices on the "Y" axis and quantity on the "X" axis (just like every other supply and demand graph)

the BLACK lines are your base graph D=demand S= Supply
now when we demand more gas the Demand curve shifts UP (meaning we want more gas aka using more)
so this new increase in demand is our redline...
NOTICE
demand goes up SUPPLY gets less...
why? because your using more DUH!

what happens when you demand more and use it up
the PRICE goes up! as you can see in the new position on the red line

so stop your stupid ignorant bitching about the government and greedy gas station owners....
if you want prices to go down... STOP USING GAS
thus the DEMAND goes down SUPPLY increases and PRICES FALL


~class dismissed

Let's go back to class then. Demand doesn't go up 50% in a single month.

the cheapest i've bought premium for my turbo is 2.33$ in the last year or so

so we'll use that saying that its 3.00$ at highest right now
thats a 23% increase in price.....now that does not reflect the ACTUAL increase in demand
but 23% is not that much...and thats on the EXTREMES

thats actually a 31.3% increase.

it's 2.79 for 87 octane. ::sigh:: my jeep gets 16.9 miles per gallon. damn i miss my celica.

-dstrb

my jeep got about 14... thats why i bought a celica. lol.

Of course, on my last fillup, the celica only got 15.5... battery has been giving me problems lately.

I guess I did pretty well for myself this morning. I only paid $2.97 for 87.

I have slowly converted my heard of vehicles over to all Toyota except my motorcycle.

I had a Chevy K2500 4x4, extended cab, long bed truck. I just sold it because it was costing me way too much in fuel. I was only getting between 11-12 mpg with it. I used to do side work with it but I haven't been getting enough work to justify the cost of running the bohemeth.

I got a 93 Toyota 4x4 instead. I just about doubled my mileage.
