OCTANE OF FUEL
I just came back from a trip to oregon. on the way, I stopped to refuel at different areas and I noticed gas octane ran from 91 to 93 octane. Is there any reason why gas isn't made the same. is this to save the refinerys money or is it done for emissions.also will the difference of just 1 to 2 octane have any effect on performance :chevy

Re: OCTANE OF FUEL (ROD BROWN)
One or two octane points will not make much difference, because the car can conpensate. If you run lower octane (like 87) you run the chance of problems and reduced power/timing,etc. I recently found 90 to be the highest in some parts of the Great Plains region. My daughter has a SunOCO station with 94!! Wish I did too.........

Re: OCTANE OF FUEL (ROD BROWN)
Octane Rating is primarily dependent on population density. ie. large metropolitan areas. It isnt prudent for a filling station to have a tank of 93 octane for instance in a town of 100,000 thousand. In Cities like Dallas, its everywhere, because the type of vehicles requiring it are much more prevalent.
So basically its a supply and demand issue.
