CAM2 = Generic name for Sunoco products where Sunoco brand name cannot be used.
Code:
VP C-16 MON = 117
Sunoco Maximal MON = 114 ( High rpm, sunoco's fastest burn rate)
Sunoco Maximal #5 MON = 113 Oxygenated
Sunoco Supreme N.O.S. MON = 113 ( high lead blend)
Sunoco MX-114 MON = 110
Sunoco Supreme MON = 110
Sunoco Stealth MON = 110
I'm guessing its one of the last 3 given as how folks like to brag about the RON octane even though MON is more useful for performance engines.
If you can get any literature on the fuel such as its color, oxygen content and specific gravity you could probably pin down what blend it is.
