Gas prices on the move again
 

Went to fill up and the price of gas has gone up 16 cents since last fill up 7 days ago. Is that just in the south? That's why we need this site. Thanks Matt

Nah, it's gone up around
 

Nah, it's gone up around here too. I haven;t bought gas for 1.5 months since my car ain't running so I dun really know how much it has changed up here, but yesterday one of the cheap stations was at 2.12 and the other was at 2.27, so I assume their in the midst of changing up.

One of the things no one on this site has done is tested the gas from different stations, as there is generally considered to be a difference among the additives and what not.

I messed around with this
 

I have messed around with that a little but the process would be tough to do because you would need several tanks to get the old gas out and each pump shut off might not be the same. I've kept track of it and there is a noticeable different in vendors. Listed below.

Do you need to worry about tier two gasoline if you're running Acetone and GP-7? I would think you would just run the best for MPG and not worry because that stuff would be cleaning and cutting emissions. Which bring up a another question. If you do not show any improvement running the acetone or GP-7 do you continue to use for those reason?

Mazda 626
HEB 30.6
SHELL 30.8
Chevron 31.7 31.9
Citgo 35.1 33.3

Honda Van. ( wife drive this so I have no control of fillup, use of AC etc)
HEB 20.0
Chevron 21.5 20.7
CITGO 24.4 24.8 24.4

Re: Nah, it's gone up around
 

It tooks me about 30 seconds, but I just thought of a way to do this. Using an old lawnmower we can put equal amounts of gasoline from different stations into it and see how long it takes to run out of gas. This can even be done with 1/4 gallon of gas.

Anyone up for the test? I don't have a gas lawn mower (have a push mower here) so I can't do this test.

Yeah, this is what some of
 

Yeah, this is what some of the old timers do and i've thought about doing it for various things from time to time. I suspect it could be done, but will a gas station sell you 2 cups of gas?

Gas prices
 

Prices in the North-East have also increased starting about four days ago (that I noticed). 'Cheap' fuel stations are $2.35 87octane and average stations are $2.45 87octane. Such is life. Anyone hear any 'forcasts' for increases in prices towards $3.00 again?

Quote:Anyone hear any
 

I heard that in Indiana at least, that gas is supposed to hit $3 by this summer. :-(

Don't care anymore. Found a
 

Don't care anymore. Found a better way to get better gas mileage. Get into overdrive as soon as possible.

87 octane next to my house $2.65

Just spiked to $2.499 in
 

Just spiked to $2.499 in Pittsburgh.

increases
 

looks like it is going up about a penny a day for the past 2 weeks - should have filled up mid week - prices are way up already - was 2.099 a couple weeks ago now 2.319 - 2.499 for 87

we have web sites here to price the gas

Re: increases
 

Those websites are available for everyone. SOme creative person purchased _______gasprices.com for every major metropolitan area and every state.

You can also check out www.gasbuddy.com to get your local gas prices.

I use
 

I use losangelesgasprices.com same site as any _______gasprices.com

Of course most the time I can't use the stations that are posted there because they are too far away but I still post prices for other people to see.

I'm up for the test. Think
 

I'm up for the test.

Think the oil in the mower should be changed every test? lol, we could even test various oils out that way...?

I do think the test would be better if I let the mower cold soak for one day before the start of the next test.

do it. I personally think
 

do it. I personally think Shell will get you further.

agreed
 

ok. And I personally agree with you as my best mileage this winter was Shell. Should I start with Shell? Where to from there?

hot cold
 

Hummm . . . maybe you should start with the engine already hot so to make the test go faster and eliminate any other variables. This way you run it dry on one fuel and refill with the next and start with a hot engine. This will allow you to run more tests more quickly and perhaps repeat the test for more accurate readings as well as in case the engine changes operation from test to test. Will also allow testing with additives as well. You may want to run a funnel for a gas tank instead of the regular tank so you can see the fuel used to the last drop and add it more easily or even a long clear hose to watch the fuel being used.

gas went up here too last
 

gas went up here too last week. from mid 70's (cents/liter) to 94/L

0.94 * 3.785 L/gal (US) = $3.5579 CAD / gallon(US)

= $3.07219 USD/gallon(US) at yesterday's exchange rate

i think the highest i have seen locally was 98 or 99/L last fall (katrina)

the lawnmower test is a good
 

the lawnmower test is a good idea. i'd like to see the same brand of gas run through the mower several times in a row, to get an idea of the variability of the test.

Me too. But how many times
 

Me too. But how many times would statisticly be worthwhile? Three maybe? So far I am going to start with shell. I can use the funnel method to be accurate on the amounts used also.

Exciting! Post this up in
 

Exciting! Post this up in the experiments thread so it's in a proper area.

Also, what kinda lawnmower will you be using?

And what's the funnel method?

Re: Me too. But how many times
 

If you had the time, three would be good. Record as much data as possible (temperature, time from start to stop, how much gas used, etc).
I wish there were a way to automate it, but I can't think of a way to do it, UNLESS you set up a video camera and play it back later with the timer to figure out start and stop time.
