They sell or at least used to sell Phillips B32 at RF. I think they call it 110, which is it's pump (R+M)/2 octane rating and Kath called it 114(it's research octane), when they used to sell it. But it's motor octane is 106, which is the important one. C16's motor octane is 117. Most "110"s you find around will have a motor octane in the 105-106 range.
