> CanadaHi guys I started out running on the 87 octane in my 97 V8 but at about 6000 Km. I did a
test of my truck on a 500 mile trip to Edmonton and back on the 87 and then on the 97
and found about a 2 mpg. increase so thats all Ive been running since.Now I now this
could be just due to the motor breaking in but who am I to argue. bye for now Bruce
