All of the gas stations in the Asheville, NC only have 87 octane gas.
What is the best way to boost the octane of regular?
Would an octane booster or some toluene do the trick or should I just put her up until the 93 octane is flowing again?

I'm almost out of gas and don't want to have to drive the old Ranger if I can avoid it.

Thanks in advance for the advice,
Jeff
