Just a question for everybody that uses, 94 octane fuel from Sunoco...I use 94oct all the time, since I've been the ower of my civic, that is all the car has seen. So with that in mind, why is it that about 20% of the time it seems that I go through it as if it were 87crap. I filled up on Wednesday, and already down to half a tank- no extra driving involved. (I can go for about a week on a tank). I'm aware of the effects of atmospheric pressure, temperature, and drivability.

I find myself driving to different gas stations to try out the quality of fuel from there! I don't know how you TCC members feel about this, but I'll tell you one thing when I'm paying as much as $0.90 / liter, I expect to get the best of the best...

Has anyone done a study, or heard of one where they can research the quality and octane rating off of normal pumps...How do you know that you are getting 94oct??? I've heard of Gas Stations "watering" down the pumps, maybe this is all it is, I dunno.

Some of you may think I've gone comepletly crazy for taking this to great unattainable lengths, but I was just curious to know what everyone here thought?

Are there more people out there like me???

I'd like to put my $0.02 towards quality of fuel!

I feel the same way, I always fill up on Sunoco 94. IMO it's the best fuel for my engine. Other people say it's the same no matter where you go. For example last Friday I put in Esso's 92 just b/c it was the cheapest station and I feel the car running like ****.

Does anyone in this club work at a gas station? Maybe we can get some inside info.

from what i've heard ESSO is the worst the have the highest water and sulfer content in the gas or something.

I use Sunoco because its good and for CAA

I've also heard the quality of fuel from Petro-Canada is very very good... and i don't know if anyone can confirm this, but i believe Canadian Tire gets its fuel from Petro-Canada.

the higher the octane you use the worse your fuel milage is going to be unless you have set up your timing for the higher octane....the engines in stock form are setup for 87 octane....

imported_cet_civic

I will have to disagree with this on the basis that higher octane fuels burn cleaner and more efficiently. 87 octane fuels have a tendency to pre-detonate proving to be less efficient than higher octane.

sorry gatherer...

imported_cet_civic

I do agree with the fact that advancing the timing and / or mods to run with the higher octane fuel, but my arguement is the fact that a higher octane fuel is a slower burning fuel, resulting in better fuel effieciently, right?

I realize that by using more octane than you need will not help power, the slower burn rate will actually cause you to lose some power. But because I'm running a stock engine with 230K on it I'm trying to prevent "pinging" as much as possible, until I can swap it.

imported_gatherer

yo the higher the octane number the slower the burn rate of the fuel ..... therefore the reason to advance your timing.... I know what I'm talking about

imported_cet_civic

Did you read my previous post....I said I agree with that.

imported_gatherer

sorry yes I agree with your posts.... I'm still wakeing up

I run 87 all day long!!! ALL DAY LONG **** 94, unless you drive a WRX or a Type R. Your computer is calibrated for 87, and that's what should be used. Once I get the turbo strapped on, then it'll be 94 (to-da-izzo) from Sunoco, but on a mostly stock motor that's not currently knocking, you guys are killing the cat, plugs, and contaminating the engine with carbon deposits. Higher ocatane means harder to light... so like gatherer said slower burn rate. This is why it stops pre-ignition (detonation). If you wanna be really safe against detonation, run some diesel in your car Just kidding, don't do that!

oh, and lower ocatane reduces emissions... if you're trying to pass an e-test, and high octane causes lower exhaust gas temps... so less power. The point is to get as violent an explosion in there as possible, while not blowing or melting anything

I have a tendancy to switch , I really believe that my car is a women . Some days she wants a steak dinner to perform other days she'll be happy with kraft dinner. Just find she has here go fast days and her no power days

imported_gatherer

bond by doing that your creating layers of octane gases in your tank...unless you run the tank empty first before filling up

Ever think the go fast days and the go slow days have to with air intake temperatures rather than fuel Like the fast days are frequently in the spring and fall, and the slow days are generally HOT summer days? Car's a woman huh? *cough*freak*cough*

Oh well ..... SHyTE happens

proud of it

gatherer, not true... what do you think 89 octaine is... they mix bronze and gold... and sell you the mixture. Gasoline won't seperate over the period of a month. I use STP stabilizer over the winter time to keep the gas good to go cuz draining a tank is no fun at all.

imported_gatherer

maybe I need to stop hanging out with a dumbass then ... I think it's rubbing off on me

imported_cet_civic

thanks for all the info everybody, sorry about the confusion bbarbulo. I just was wondering why, my car burns 94oct faster on other days, and slower on most days, I thought it was related to fuel pumps, and the "watering" down effect.

And I didn't know if there was a way to determine that you are getting what you pay for!
