Whats Your Octane?
 

Couple Questions:

Make of Car:
Octane of Fuel:
Do you notice a difference:
Is it worth the money:

For me,

99 Civic Si
Regular 87 Octane

Never tried anything else.
Dont have the extra money to waste on it either.

91 octane.
I don't know if theres a difference, I've only used 91 with this motor. With a full tank of gas I guess pretty good mileage tho, 530km's off a full tank. and a full tank of premium is usually 40 bucks for me.

Today, pull up to the 7-11 gas station, "SORRY, WE'RE OUT OF REGULAR''......... meaning........... yess... Premium for the price of regular. 35 bucks to fill it up I was tryna squeeze in as much as I cud. xmas doesn't usually come around more than once even tho this has happened to me twice and its great everytime it does

happnd last night to:D

what engine are you putting this 91 octane into:?

05 civic si
87 octane
honda recommends using 87 octane , + why would i pay more for gas when i dont have to lol

every one uses 95 here, and 97 high

Isn't this question a little too personal?

use whatever is the cheapest....

2002 F150

93 Del Sol SI

91-94 Octane

yep.. and using higher octance when it isnt required will just yeild ****ty fuel economy

SiR-Diesel.

my car has this new sick engine that allows a mild mix of pisss and water combined to create a new Fuel ...

99 SiR...supposed to use premium, so that's what I use. Costs more but whatever...wanna play, gotta pay!

2000 Civic SE - 87 octane.

Make of Car: 2001 Honda Prelude
Octane of Fuel: 94
Do you notice a difference: yes
Is it worth the money: yes

Prelude is premium only anyway. Only issue I have with 94 is that I burn it 25 km faster than 92.

Make of Car: 89 Hatch
Octane of Fuel: 87 octane
Do you notice a difference: no, I don't waste my money on what my car doesn't need, it doesn't have the compression to justify higher octane, thus it wouldn'd do anything (and why its not recomended)
Is it worth the money: I guess

that "do you notice a difference" question is stupid, it should be "I dynoed my car and there was a recordable difference"...that would be impressive, I'd be willing to bet that a lot of people who put in higher octane because they think they will get better performance will just say it will so they don't look stupid...

Make of Car: 2006 TSX
Octaine of Fuel: 91 octane
Do you notice a difference: 91 octane is where it's at, 94 octane results in decreased performance and decreased fuel efficiency...

if u have a stock civic from what i remember using higher octane gives you less performance and less fuel efficiency...

why bother? it's like throwing money down the drain...

Make of Car: 91 civic
Octaine of Fuel: 91 octane
Do you notice a difference: my B series is supposed to have 91 so it gets it!

Make of Car:97 civic hb
Octane of Fuel:94
Do you notice a difference:run's better
Is it worth the money: i donno?
