"Short Wave Sportfishing" wrote in message .. . My 'Vette is an entirely different story. When I took the blower off and downsized from twin 950 Holleys to single, put the rear end back to street legal and changed over from street drag slicks to street legal tires, the mileage went up marginally - from about 6 mpg to maybe 10. I went from 645 hp on a dyno to just south of 400 hp. Think it might help if I took the 3/4 cam and NOX out of it? :) The '67 GTO needs 91 octane or better and even then it will still "knock" a bit if you get on it. So, I don't. I thought about retarding the timing a little, but I drive the car very infrequently and baby it when I do. I'll just leave it alone. The '63 Galaxie with a 390 seems very happy on 91 octane. Again, I only drive it for a few hours per month, so it's 10 mpg isn't a big issue. Are the higher octanes 10% ethanol or is it just regular? |

If I remember correctly, around here 87 octane is "regular", 89 octane is "plus" or something, 91 octane is "high test" .... and then Sunoco sells 93 octane as "Ultra". I seem to remember that many years ago Sunoco used to sell a very high octane blend .... something like 97 ... for the muscle car crowd. Eisboch |

Ethanol is supposed to have a higher octane rating than gas, so the gas part of the mix has probably been lowered in terms of octane. I don't know. Eisboch |

Porsche really has nothing to do with them other than the fact that Fearless contracted the Porsche design group to come up with the "look". Eisboch |

I just filled it up and will check it the old fashioned way ..... mileage driven, gallons used. I think I'm getting a bit more in the X5, too. I'll have to try that. Have you ever run mid-grade in your German cars? I know the computers will adjust and the fuel economy can decrease. I never tried anything but "high test". When we had the BMW's, the price of gas wasn't an issue, so there was no reason. One downside of the Porsche is that it calls for 93 octane (minimum). The only place I can get it is at Sunoco, who still carries 93 "Ultra". I've often considered taking it over to the little Plymouth airport where I took flying lessons and see if I could buy half a tank of 100 octane aviation fuel to mix with the 93 octane. Problem is that I think aviation gas is still leaded, and it would probably screw something up. Mrs.E. had a good one the other day. Her Navigator calls for "high test" (91 octane). She was giving me a ride back from the Cape after I brought the boat down there and I noticed that her left directional was blinking twice as fast as the right. I mentioned to her that one of the blinker lights was probably out. Her response? "Oh .... is *that* what it is? I thought it was because I've been using "regular" gas instead of "high test" ever since the price of gas hit four dollars a gallon. Some people should stick to horses. Eisboch Keep it up and you will be mucking stalls forever. |

I see that sticker on their pumps and pass by. My gas sucking pig, 2001 F-150 5.4L, gets 20% less MPG when the fuel contains ethanol. |

There's a Sunoco station in Ashford that still sells it I think. |

It really is an amazing car, given 445hp, it's performance and it's fuel economy. I should drive it all the time. A car like that should be in a better climate. Let me store it for you here in Florida. :-) |
