[Spridgets] No LBC - Premium fuel

This is my experience exactly, There is an Arco a block from the Grange
(where I normally fill my tank).
At the Grange I get pure gas and the high grade stuff is currently $4.09 /
gallon.
The Arco has regular with 10% ethanol for $3.79 / gallon.
When I use the Arco gas I get about 25 mpg.
When I use the pure premium I get 30 mpg.
My fuel efficiency increases 20% and only costs me 8% more.
Driving with the Arco costs me 15.16 cents per mile.
Driving with the Grange's premium fuel costs me 13.63 cents per mile.

I think there are other benefits (seat of the pants) but purely financial
math says using the best gas is cheaper.

Hello Michael,

    I just checked and this car IS equipped with a knock sensor. It
    will automatically adjust the timing when it senses regular gas.


    a side note is that the fuel economy will most likely suffer by
    almost exactly the amount or MORE than the cost of putting in
    premium. .. that is if premium costs 5% more, the fuel economy
    will suffer by at least 5% by using regular gas...... do your own tests
 though

    YMMV
