Fuel for Gassers
Anyone run Premium fuel or Octane Boost? Improved performance/mileage or waste of $$.

Octane ratings are, at least in most areas, posted on the pumps. 87 octane is regular gas, 89 is mid range and 91 is premium.
Some areas in the plains states there is 85 octane. My 7.4 TBI doesn't like it.
