NOT 94 Octane.

oh trust me, even worse!!
read them again...
most of addtive says "up to 5 points", "up to 10 points", or "up to 20 points"
what does that mean?
it means it goes up anywhere from 0 to 20 points,
so u might get only 1 points after all....who knows?
87+0.1=87.1
wow....how sad~
From my experiences, add a bottle to a full tank.
u wouldn't feel any difference....
and it actually reduce the gas mileage for that tank of gas with booster.
what I mean is:
a reguler tank of gas: 36 mpg
tank of gas with oct boost: 30~32mpg
they do help clean up ur fuel injecters though,
so it's not bad to use it once a while.
anyway, I wouldn't recommand to use them on old cars,
cause the alcohol from the booster tend to destory or aging
fuel lines made of rubber, gaskets.....etc.
