Hi All,

Rember a few months ago we had an argument on difference of gasoline, brands and octane. Well, I have the results for 92 and 89 octane. All tests done on a 96 964 in warm temperatures, mostly highway driving. Max speed on FWY was 100 MPH

Chevron 92 High grade MI Traveled

Tank 1 <2.10/gal> 18.235 gal = 38.29 450.9 24.7 MPG {11.775 MPD}

Tank 2 <2.05/Gal> 17.953 gal = 36.80 429.8 23.9 MPG {11.679 MPD}

Tank 3 <2.03/Gal> 19.105 gal = 38.78 469.6 24.6 MPG {12.109 MPD}

Tank 4 <1.97/Gal> 18.756 gal = 36.95 459.7 25.4 MPG {12.441 MPD}

MPD= miles for each dollar spent

MPG= miles for every gallon

Chevron 89 Middle grade

Tank 1 <1.83/Gal> 17.532 gal = 32.08 392.7 22.4 MPG {12.241 MPD}

Tank 2 <1.95/gal> 17.353 gal = 33.83 374.8 21.6 MPG {11.078 MPD}

Tank 3 <1.90/Gal> 18.642 gal = 35.41 425.0 22.8 MPG {12.002 MPD}

Tank 4 <1.88/Gal> 19.203 gal = 36.15 399.4 20.8 MPG {11.049 MPD}

I did not start on the first tank, as I felt it necessary to flush out the cars system with the new fuel. For the second stage I did the same to ensure even results. When I did change fuels the MPG went down considerably because the lower octane has a harder time at High RPM’s. The MPD (Miles per dollar)changes with the price of gas and with the car’s gas mileage. The average for 92 octane is 12.001 miles per dollar spent and for 98 octane the average is 11.5925 miles per dollar. The average MPG (miles to the gallon) for 92 octane is 24.65, and the average for 89 is 21.9. Wel, Dave all your BS knowledge on gasoline proves that you are ignorant when it comes to gasoline. As I continue with my experiment I will post back in about two months or so with the results of Chevrons 87 octane, then with Arco’s 92,89,87 octane. Please feel free to post Questions and comments. If you want me to further explain a part of the experiment in detail l I will.
