Wonder if it would run better, and cleaner too
it's good to throw it in once in awhile, but you wont see any improvement from it unless you do something like f/i, nitrous, higher compression, or advance the timining. If you do any of those anyway you'll have to run higher octane or you'll go boom
can you advance the timing on an aveo? Ill have to take it to my friend next week then and see what he can do, that would be interesting.
I throw in a take of premium everynow and then. Mostly I just run the Aveo on regular unleaded.
I hear NOS drinks work well too.....
I run premium once a month just out of routine. It helps keep it clean, but you burn through it faster lol.
The only way to do that is to do the resistor mod either on the IAT sensor of Coolant temperature sensor.Quote:

The difference is very tiny if anything and would take awhile to do anything, Seafoaming is somewhat the same thing cept it's more concentrated and just absorbs the carbon buildup and burns it off. Premium gas does the same thing it's just not as effective.
The difference between different grades of gas is like comparing vodka to beer, it's in the refining process. The more refined it is the more pure it is and more powerful it's combustion is. Premium gas has just had more refining than unleaded, in which case it has less particulate matter and free roaming carbon atoms to attach to your engine or reduce efficiency.
At least that's what I understand about fuel...
All I know is JP-5 jet fuel is so strong it can literally dissolve through metal if left alone, which is why planes use special bladders to hold it.

lol hell no, who would use those stupid things :lol:Quote:

Definetly a touchy subject...
Your car is not getting treated by giving it a higher octane fuel... refer to google for more on this, also here are some links.

I'm not seeing the article I was looking for, but basically lower octane should give you more power unless your ECU is capable of compensating for the octane. Lower octane burns faster and therefore will give you a little more timing and hence power. If your car can compensate for the higher octane, then it burns slower, allowing more timing and more power.
Theres no difference between fuel from one gas station to another.Quote:

Some companies will add additional additives but the government regulates what they are allowed to put in and by how much as well, and since the fuel you get is the exact same no matter where you get it from, Chevron has very little room in terms of proportion of gas/additives to add more stuff.
It's called marketing...
And it's used to try and make people think you sell better stuff than your competitors even though you sell the exact same thing...
Touche', however here in AK quality of fuel is a big problem, where-as not so much the fuel but proper maintenence of the stations tanks. We have a big problem also with water condensation in the fuel when the temp drop into the severe negatives the molecules seperate, as if your car running like crap from water in the fuel isn't bad enough it will actually freeze in your fuel lines lol. Chevron up here cleans they're tanks frequently and treats all their fuel with an additive compariable to HEET. Diesel fuel is hell in the arctic lol.
man why do you live in AK? :lol: :lol: :lol:
I have only HAD to run Cheveron at one time in my life.
I had a GLH had problems running on anything lower than 92 octane.
And just sounded healthier on Cheveron.
Man, I love it up here. I mean the weather is severe, but it's amazing up here. I'm never living anywhere else.
i always use 89 from shell then about every three fill ups ill do 93. its to expensive to run 93 the whole time so yeah
Shell is good. Nitrogen Enhanced! lol
Fixed it for youQuote:

I agree to a point that indeed the Federal Government does require fuel to have a "minimum" amount of cleaning additives added. Please note however, the distinction between "minimum" amount of gas cleaning agents and Top Tier gas is the amount of these said "cleaning" agents added to the fuel. There is a difference between one gas station and the next. See :Quote:

Here is a list of current gas stations that meet this stringent "top tier" goverment staus label in the US.
76
Chevron
Conoco
Entec Stations
Kwik Trip/Kwik Star
MFA Oil Company
Phillips
QuikTrip
Shell
Somerset Refinery
Texaco
Tri-Par Oil Company
Now these companies do vary the amount of cleaning agents to their gasoline to octane level but regardless the amount is still above the "minimum" requirement set forth by the goverment. 93 octane will have more that 87 octane. 87 octane will still have more of these cleaning agents that madated by goverment with it's Top Tier status.
So all in all stay with these stations and choose the lowest price within the top tier gas and you will do great. :mrgreen:
I dont worry too much about the price when it only costs 20-25 bucks to fill up lol.
87 octane burns "cleaner" than 93, the higher octane is its resistance to burn.
If you are running 93 octane it is not going to do anything to clean the system. If anything it will enlarge the possibility of dumping unburned fuel into the exhaust and ruin the O2 sensor and CAT.
The more cleaning additives in the higher octane are because they do not burn efficiently either, so since you want the fuel to delay igniting, you can add more cleaners etc to it.
I know there is a lot of "thought" on the topic. but the only reason anyone can even claim that the higher octane does anything to clean your engine is there is a measurable difference in the operating temperature of the engine when you run a higher octane gas. meaning you are sort of overheating your engine to clean it.

This article kind of restates what was said earlier, particularly number 3 but I figure it would add some credibility to the subject.
Screw it I won't ever burn anything over 87 octane, the way I see it why in the hell would I WANT to pay more for fuel.... that doesn't make sense. It's like saying.. ok kids we ran out of newspaper to start the furnace we're going to start using dollar bills now instead.
maybe dollar bills burn better...
who knows :lol:
They turn funny colors when they burn. It's great for the kids! :lol:Quote:

They do actually burn better than newspaper. The venting in the cloth makes for a cleaner more complete burn.Quote:

If the owner's manual does not specify that the car REQUIRES anything over 87 octane, then don't use anything above 87 octane.
'nuff said.
Some higher-end vehicles can only use premium ( like some Lexus's and Acura's), because they are designed for it. But any notion that premium gas will make an engine designed for 87 gas "run better" is simply psychological. ONLY use 87 octane! Don't waste your hard-earned money.
This may be an older topic, but i need to add my 2 cents LOL. When I run regular unleaded in my Aveo, I average 28mpg, (mostly city driving) when I run premium unleaded, I average 32mpg an extra 40 miles of driving to me is worth the $1.50 to $2.00 fill up difference. Back in the day, when I was a Lincoln Tech student, we had a homework assignment to go to a gas station and obtain a sample of gas, over the time frame of 2 weeks, everyones samples had a chance to settle. their were huge differences between Gas stations, most big names were better than smaller names. Im in Texas, we had several samples from multiple racetrac locations through out dallas and Fort Worth, from 6 or 7 racetrac samples, their were all about 35 percent water and all had debris floating in it.
Hey Paul I'm with you and going to throw a comment here on this ancient thread. I have noticed myself that even though premium is more expensive I do notice an increase of mpg. Typically my automatic gets 30 mpg with 87 octane. When I run 93 octane it increase to 33 mpg. I have done this several times just to make sure this wasnt a fluke.Quote:

You see those pumps that say up to 10%? well regular most likely has the 10%, where as premium might only have 8% Super might have 6% .(regional names? 87, 89, 91ish respectively). ethanol is not as fuel efficient as gas is. So if you run 100% true fuel, then the mpg wont change with octane changes. but the displacement of the ethanol will..
How ever at the same time you risk having unburned fuel into the exhaust, eventually clogging your cat and seizing the engine. You might pick up timing issues. The added octane does not burn the ethanol more efficiently.. its just there possibly is less there.
If you find a gas station that uses the same amount of ethanol in every grade of fuel. you will see the same fuel mileage.
The best thing to do would be find a filling station that does not add ethanol, and buy their 87 octane. It would probably provide the BEST fuel economy, but good luck with that i think when gas prices went over $3 a gallon, ethanol got put into everything.
