I know in the manual for my car it reads that gas over 91 oct is needed, however alot of people say that "oh in canada our regular gas is ok since its a higher value then in the US so its fine"
Though ive heard from other people that its just dealer bull shit and they dont want people thrown off from thier cars by the fact that you now need to spend a extra 6 bucks at the pump every time.
So has anyone here acctualy used normal gas and found a lack in performance or negative effects on a vehical that reads premium only? |

If your manual says 91 you need 91. Plain and simple. |

| 91 octane helps your car perform better. Dealers always say DOHC Vtec engines should use 91 octane. |

it's just that easy. Spend the extra 10 bucks a tank and get premium. I know that Honda very strongly states that there DOHC motors be run on premium. |

| Qoo |
my stupid theory is...
if you gonna shift under 2.5K
you are ok with 89.
:dunno:
it is base on a dream i had last year about I am inside the GT4 game where you have to fill up the gas to every lap.:thumbup: |

That is absolute bullshit at its finest.
In Canada the pump octane rating is the same system used in the US --> (RON+MON)/2 |

Your engine RPMs aren't going to alter your compression ratio. If your car asks for 91, run 91. It's only four or five bucks more a tank and the benefits are definitely worth it. If you run lower octane fuel your engine may adjust timing to accomodate for it and you may end up losing mileage and forfeiting the majority of the money saved anyhow.
For those people who say octane doesn't make a difference. I was able to run 87 octane in my Z so long as I turned the boost to stock 6psi, any higher and it would knock. By running 94 octane I was able to run 15psi on even the hottest days without detonation. That right there proved the benefits of higher octane fuel to me. |

Lower than what the manufacturer requires can and probably will damage your engine because the fuel will tend to detonate before it is ignited. Lower octane ignites easier.
Think of it like pouring your gasoline in your fireplace before lighting it. Putting lower than requiredoctane in your Acura is just as bad.
That problem is even more critical in an engine like Honda's VTEC.
So as said before do EXACTLY as the manual says. Simple as that. |

| Well, car builders have to set up a engine computer to be able to run on the worst possable gas they can find, for cars that run normal 87, higher octane will alow the computer to run the engine at its best if its designed for that. if it doesent ask for a type of fuel dont put whats not need in it. |

If a car is designed to run on 87, it wont run any better or give you any better performance on 91. |

AS said in my other post, higher octane will alow the computer to run the engine at its best IF ITS designed for that. if it doesent ask for a type of fuel dont put whats not need in it.
You have to be the worst ant not reading a post start to finish, i know my gramer is the best but its understandable., |

Perfect example of this is a dodge/Chrysler Neon R/T.. yes I know "EWWW a Neon" but the R/t is designed to run on 91/92, by using 87 or 89 the computer retards timing to adjust for this, and due to retarded timing the car looses power, not much mind you.
At 15cents difference between reg and premium, it's a $10-$11 diff per tank for me... I use mid/premium in the summer when my car appears to need it, in the winter 87 seems fine(no knock)

seemed like you were trying to say that the car was designed to run on 87 would perform better on 91. |

| Nope, not at all. a computer can idendifi when better gas is in it, but it cant run the engine better. |

THIS IS A LOAD!
If the octane is lower than it should be, the computer should have to advance the spark not retard it.
Lower octane will spontaneously combust in a high compressioin engine like that if the timing is retarded.
Fact is, using lower octane than required is like running your bbq on gasoline. Should never be done because it is not safe for your engine. |

Higher octane fuel is more difficultt to ignite, and burns more slowly, than lower octane fuel................
If you burn lower octane fuel in your engine than it requires, the biggest effect will be that it will tend to ignite prematurely in the cylinders, not waiting for the spark plug to ignite it. This causes “knocking” and “pinging”, with an accompanying loss of power, and, in extreme cases, can and most likely will damage your engine. |

think of it this way 91 octance is more potent then 87 octance.
think of it as 8:1 and 3:1
The rest should be obvious |

Ok... I know it changes the timing the help prevent detonation.
My R/T engine sounds the same with 87 as it does with 94 or 92 or 91 or 89....
The car is very lightly used now, it basically coasts down a hill 5km, parked the putts up the hill 5km and parked. Any actual trips it gets proper fuel.
I'm not spending the extra $7.50/tank for it to be idled away, last winter the wife got 60km/tank cause she idles it to damn much in the winter. |

| JonJonPoPong, you have 37 grand to buy a new car but you are worried about 5 bucks a week in gas? Something is really wrong there. Don't be so cheap and fill the car with what is recommended. And if 5 bucks a week is that much trouble for you apparently you bought the wrong car in the first place. What are you going to do when gas goes back up over a buck a liter? |
|
|
| JonJonPoPong |
| Dood, im cheap. But yea if usen regular will hurt the car, then yea ill put in premium, i just try to find ways to save money, if i dident i wouldent have the 36k it cost to get the car now would i? |
|

| Claw |
Oh jeebus... let the posty posts begin!
Anyhoo, if you can afford a nice car that drinks the best, why are you going cheap with the gas?
That's like "oh, I'm gonna buy me a Ferrari and feed it 87 octane." |

| Buy your groceries at safeway and get their 7cents of/litre coupons. Then poof.....your premium costs the same as regular |

| ya but safeway marks the prices up more dont they?? And where can you get 94 octane gas in the city i just want to know |

Husky.. St Albert, 153ave and like 78st... a couple more locations |
|
|
| Turbo_Civic92 |
| oic thanks alot i never knew where to get 94 octane and your saying the huskies sell it at the locations you said?? I'll have to see somewhere closer to the park |
|
|
| SilverNeonRacer |
I think there might be a location in the park, there's one on the south side, maybe two...
Newer or newly renovated places seem to have it. |

Thats bass ackwards... if you can manually control timing, you will run more advanced curve with a higher octane. If you are running a crappier fuel, you can dial back some timing to avoid detonation under load.
More octane is better because it can stave off detonation longer for higher levels of compression or timing or boost (which creates more power). But it actually creates less combustion energy, so if your vehicle is unable to sense which fuel its running, you will get more power out of 87 than 91. So all things being equal, you will get more power out of 87 than 91 if you aren't detonating from the lower octane :) |

no....they are the same price as everywhere else before the coupon discount.........and safeway uses Esso gas |

| Funny.. did they switch? cause the few times I used it my milage was horrible compared to esso. Mind you I used them when they where new. |

| hahahah ur a funny guy. 91 octane is 91 octane... doesnt matter which country it is in.... thats like saying i can eat 24oz rib eye steak in canada but only a 20oz in the africa. |

But it's not the same as buying a gallon of fuel in Canada and a gallon in the states :P
Not really sure who your comment was too though.. quite a few posts back I'm guessing... |
