V V ers,
Of course Bob is correct! It was PUMP octane that I should have
referred to with my octane numbers. Pump octane (the octane number posted on the
gas pump) is actually the AVERAGE of the research number octane (RON) and the
motor octane number ((MON). The the pump number is = (RON + MON) / 2. This
comes from the two different methods used to measure octane, one is the
research number and the other is the motor number. So the number you see on the
pump is the average of those two methods.
Thanks Bob for giving me a much needed correction.

Let's get back to basics. In my area, Premium fuel (93-94 RON) costs
only 20 cents more than Regular gas (87 RON).
Hi Frank,
Just a question. Are you sure it's RON and not pump octane? I believe the
EPA requires all octane to now be stated as pump octane = (RON + MON) /2.
