yea i'm so jealous you have 94 down the road from you RT b/c thats how far it is from me. btw how much per gallon or on average if premium is usually 30 cents a gallon more than reg so is 94 another 30 cents ? Anything higher then 91 octane will not make a difference. |

We Used to Put Regular in ours From Brand New, But Just recently like last year WE started putting Regular in it Too Much $$$$$ For Premium, But When I get It I'm putting in Premium

Anything higher then 91 octane will not make a difference. Why? Our engines simply don't need anything higher then 91. Further reading from the Wikipedia article on octane rating: |

Oh yeah, because wikipedia said so.  Yes, I have read that before. Feels like it runs better to me, even if it's in my mind it's still running better. Your engine may not need it, but mine wants it!  |

Mine hasn't gotten a drop of anything less than 91 octane in its life, and I don't intend to start now! It's hard on the wallet, but she deserves it!

Octane rating is the average of Research and Motoring octane as measured in a single cylinder research engine. Ever notice the R+M/2 stickers on the gas pumps?
What you get for your higher Octane number is a higher resistance to detonation - actually a slower burn. In our cars, that allows the computer to dial in more advance, and generically, more advance tends to lead to more power output, but not necessarily better fuel economy.
On the Classics, the engine had more of a need for the higher octane, on the 2nd gen's - not so much.
So...which do you run? I have NEVER heard mine knock once in over 50,000 miles of driving, so either the computer senses the knock before it's become audible, or it has not ever knocked.
I can't discern a difference in fuel economy or performance in mine with either fuel, so until I go to the strip and generate some time slips, it gets regular if they have it.

It is in your mind. Your engine can't tell the difference. As long as it has an octane rating above 91 there will be no difference. You can't argue with facts. |

I run premium in my 95 always. If i add Lucas octane booster, i can tell a little difference, but i only use that when i wanna run her hard. I am ignorant bout the 2nd gens so i will only post my own findings.

If I ever go to a dragstrip, I'll try 91. |

Did you see a part in that wikipedia article about Northstar V8's? Well there isn't one. So you can stick your 89 octane in you gashole and keep putting around. I drive WOT constantly so I am going to keep using 94 octane. I can't even take off in second gear because it spins the tires so bad when it hits second. And I have new Coopers on the front so it's not the tires. |

Your not driving that 12 Cylinder Jag anymore that must have been really bad on gas You're telling me! She took premium as well. (The Jag LOVED high octane gas. VERY noticable difference.) V12 engine built in 1989 + high octane gas + teenage kid with a heavy foot = low gas mileage. It's as simple as that. I agree with Randy on this one. Shell and BP have a higher octane "premium" here than some of the other stations in the area, and I can tell a difference when I used to buy gas from other stations. |

And I have new Coopers on the front so it's not the tires. It has nothing to do with Northstars. This is about pre-detonation. As long as the fuel air mixture doesn't fire before the spark sets it off there will be no difference. A 91 octane rating is all that is needed in our engines to prevent this from happening. Anything higher is pointless. For the record, I use gas with an octane rating of at least 91. I never said anyone should use anything lower. |

Haven't got a 1/4 mile track around here, just an 1/8 mile track about 15 miles away. I have never been there before. Do you have to do anything special like wear a helmet or anything? I would like to go sometime. I have timed 0-60 several times, when I take off in second I lose about a second on my time. And I didn't say it burns the tires I said it spins the tires.  I will see if I can get a video up this week of the traction loss. |

I have never been there, I have never been to a dragstrip. Do you have to take anything special, like a helmet or anything, or do you just drive you car like it is. I did go outside just now and try to make a video of the traction loss. I did not have any traction loss in 2nd gear, so I take it back because I cannot prove it.  I usually leave my house around 11-12 pm to pick up my wife from work. And I know for a fact I have had major traction loss. So I guess it is from the cold tires and pavement when I leave at night. I am still going to run 94 octane, though, why not! |

Last i heard if you run faster than 12 seconds in a 1/4 mile than you need a helmet. But to run your car you wont, unless the track rules require a helmet no matter what. When i run my car when she hits second, she will chirp the tires but thats it. I have mine running strong and i 2 like WOT! Still get bout 20 mpg.

I found these from a couple months ago. Occasionally when I leave my house I record so I can time my 0-60. And sometimes when I take off the tires will spin when it hits second, it usually costs me a second when it does this. If you didn't believe me about the tires spinning, then here it is. I already know about my dummy lights also, so don't bother. www.youtube.com/watch?v=4TS1saC-pIowww.youtube.com/watch?v=ugwUGrYzPJ0 |

Just as a comparison and so that you guys get an idea, for those of you who frequent the tracks... Where i go, you can fill up with 104 octane at a bit over six bux a gallon... it smells sweet I have noticed an incredible difference on 104 octane fuel and have yet to try it on the Aurora... I may just drive up to great lakes dragway in the cheese state just to get a full tank... |

Well, i tank 95 octanes. This is regular in Poland. Premium gas has 98 or 100. But gas is very expensive. 1 galon costs about 5,50 bucks !

USA gas is rated as the average of Research and Motoring Octane - that's what the little R+M/2 sticker on the end of the pump means. Not sure about European standards. If your gas is only $5.50 per gallon, you live in one of the cheaper places in Europe for gas.....I remember putting $60 worth of regular in last year.....and that was in Ohio, USA... |

$60 !?
Well, 1 gallon = 3,78 liter, 1 USD = 2,90 PLN, 1liter costs 4,50 PLN / $1,55 ( today in Poland)
So, 1 gallon - 3,78 x 4,50 / 2,9 = 5,86 bucks.
Is calculate OK?

Calculations are OK. I paid $4.60/gallon last summer for regular and it REALLY hurt the pocketbook. With your fuel mileage, it's a double shot. Most of my miles are highway. My average economy is around 23 mpg (10.5l/100km). Best has been 28 mpg (8.4/100km)

Hahaha thats what we were paying a few months ago for regular (87)! Google can do the conversion for you (Much easier then doing the math:) ) Google Conversion |
