Had some free time this afternoon, so I gave a call to Chardon Oil to get the rundown on their race gas offerings.
Here's the basic list:
cam2 purple, leaded, 110 octane (pump octane) **
cam2 blue, leaded, 112 octane
cam2 red, leaded, 116 octane
vp c12, leaded, 108 octane (motor)
vp c14, leaded, 114 octane
vp c16, leaded, 117 octane
vp u4.2, unleaded, 108 octane*
vp ms109, unleaded, 101 octane (motor)
sunoco 260gt, unleaded, 99 octane (motor)
sunoco 260gt+, unleaded, 95 octane
* New product, not yet available
** This is the only fuel sold from a pump. All others are sold in 5-gallon buckets, or by the 55-gallon drum.

He kept saying "xx motor octane" where as on the first cam2 listed, he said "pump octane". I'm guessing motor octane is the MON number.
